Updating others' answers with the new syntax:

Maybe I will provoke a bunch of down-votes and negative comments, but... I cannot stand.

Disclaimer: what I write below is not really an answer to the original question, but rather my thoughts on the topic. And the only source for it is my thoughts and my experience (with Java and other languages).

First let's check, why would anyone like to use Optional at all?

For me the reason is simple: unlike other languages java does not have built-in capability to define variable (or type) as nullable or not. All "object"-variables are nullable and all primitive-types are not. For the sake of simplicity let't not consider primitive types in further discussion, so I will claim simply that all variables are nullable.

Why would one need to declare variables as nullable/non-nullable? Well, the reason for me is: explicit is always better, than implicit. Besides having explicit decoration (e.g. annotation or type) could help static analyzer (or compiler) to catch some null-pointer related issues.

Many people argue in the comments above, that functions do not need to have nullable arguments. Instead overloads should be used. But such statement is only good in a school-book. In real life there are different situations. Consider class, which represents settings of some system, or personal data of some user, or in fact any composite data-structure, which contains lots of fields - many of those with repeated types, and some of the fields are mandatory while others are optional. In such cases inheritance/constructor overloads do not really help.

Random example: Let's say, we need to collect data about people. But some people don't want to provide all the data. And of course this is POD, so basically type with value-semantics, so I want it to be more or less immutable (no setters).

class PersonalData {
    private final String name; // mandatory
    private final int age; // mandatory
    private final Address homeAddress; // optional
    private final PhoneNumber phoneNumber; // optional. Dedicated class to handle constraints
    private final BigDecimal income; // optional.
    // ... further fields

    // How many constructor- (or factory-) overloads do we need to handle all cases
    // without nullable arguments? If I am not mistaken, 8. And what if we have more optional
    // fields?

    // ...
}

So, IMO discussion above shows, that even though mostly we can survive without nullable arguments, but sometimes it is not really feasible.

Now we come to the problem: if some of the arguments are nullable and others are not, how do we know, which one?

Approach 1: All arguments are nullable (according to java standrd, except primitive types). So we check all of them.

Result: code explodes with checks, which are mostly unneeded, because as we discussed above almost all of the time we can go ahead with nullable variables, and only in some rare cases "nullables" are needed.

Approach 2: Use documentation and/or comments to describe, which arguments/fields are nullable and which not.

Result: It does not really work. People are lazy to write and read the docs. Besides lately the trend is, that we should avoid writing documentation in favor of making the code itself self-describing. Besides all the reasoning about modifying the code and forgeting to modify the documentation is still valid.

Approach 3: @Nullable @NonNull etc... I personally find them to be nice. But there are certain disadvantages : (e.g. they are only respected by external tools, not the compiler), the worst of which is that they are not standard, which means, that 1. I would need to add external dependency to my project to benefit from them, and 2. The way they are treated by different systems are not uniform. As far as I know, they were voted out of official Java standard (and I don't know if there are any plans to try again).

Approach 4: Optional<>. The disadvantages are already mentioned in other comments, the worst of which is (IMO) performance penalty. Also it adds a bit of boilerplate, even thoough I personally find, use of Optional.empty() and Optional.of() to be not so bad. The advantages are obvious:

1. It is part of the Java standard.
2. It makes obvious to the reader of the code (or to the user of API), that these arguments may be null. Moreover, it forces both: user of the API and developer of the method to aknolage this fact by explicitly wrapping/unwrapping the values (which is not the case, when annotations like @Nullable etc. are used).

So in my point, there is no black-and-white in regard of any methodology including this one. I personally ended up with the following guidelines and conventions (which are still not strict rules):

1. Inside my own code all the variables must be not-null (but probably Optional<>).
2. If I have a method with one or two optional arguments I try to redesign it using overloads, inheritance etc.
3. If I cannot find the solution in reasonable time, I start thinking, if the performance is critical (i.e. if there are millions of the objects to be processed). Usually it is not the case.
4. If not, I use Optional as argument types and/or field types.

There are still grey areas, where these conventions do not work:

• We need high performance (e.g. processing of huge amounts of data, so that total execution time is very large, or situations when throughput is critical). In this cases performance penalty introduced by Optional may be really unwanted.
• We are on the boundary of the code, which we write ourselves, e.g.: we read from the DB, Rest Endpoint, parse file etc.
• Or we just use some external libraries, which do not follow our conventions, so again, we should be careful...

By the way, the last two cases can also be the source of need in the optional fields/arguments. I.e. when the structure of the data is not developed by ourselves, but is imposed by some external interfaces, db-schemas etc...

At the end, I think, that one should think about the problem, which is being solved, and try to find the appropriate tools. If Optional<> is appropriate, then I see no reason not to use it.

Edit: Approach 5: I used this one recently, when I could not use Optional. The idea is simply to use naming convention for method arguments and class variables. I used "maybe"-prefix, so that if e.g. "url" argument is nullable, then it becomes maybeUrl. The advantage is that it slightly improves understandability of the intent (and does not have disadvantages of other approaches, like external dependencies or performance penalty). But there are also drawbacks, like: there is no tooling to support this convention (your IDE will not show you any warning, if you access "maybe"-variable without first checking it). Another problem is that it only helps, when applied consistently by all people working on the project.

For some projects it's easier to set your target to es6 in your tsconfig.json.

{
  "compilerOptions": {
    "target": "es6",
    ...

You're the victim of the classic deadlock. task.Wait() or task.Result is a blocking call in UI thread which causes the deadlock.

Don't block in the UI thread. Never do it. Just await it.

private async void Button_Click(object sender, RoutedEventArgs 
{
      var task = GetResponseAsync<MyObject>("my url");
      var items = await task;
}

Btw, why are you catching the WebException and throwing it back? It would be better if you simply don't catch it. Both are same.

Also I can see you're mixing the asynchronous code with synchronous code inside the GetResponse method. StreamReader.ReadToEnd is a blocking call --you should be using StreamReader.ReadToEndAsync.

Also use "Async" suffix to methods which returns a Task or asynchronous to follow the TAP("Task based Asynchronous Pattern") convention as Jon says.

Your method should look something like the following when you've addressed all the above concerns.

public static async Task<List<T>> GetResponseAsync<T>(string url)
{
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
    var response = (HttpWebResponse)await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);

    Stream stream = response.GetResponseStream();
    StreamReader strReader = new StreamReader(stream);
    string text = await strReader.ReadToEndAsync();

    return JsonConvert.DeserializeObject<List<T>>(text);
}

Just to clarify given the following object

$Object

With the following properties

type        : message
user        : [email protected]
text        : 
ts          : 11/21/2016 8:59:30 PM

The following are true

$Object.text -eq $NULL
$Object.NotPresent -eq $NULL

-not $Object.text
-not $Object.NotPresent

So the earlier answers that explicitly check for the property by name is the most correct way to verify that that property is not present.

This is what events are for.

HTMLInputElementObject.addEventListener('input', function (evt) {
    something(this.value);
});

Preface

Java is nothing like C++, contrary to hype. The Java hype machine would like you to believe that because Java has C++ like syntax, that the languages are similar. Nothing can be further from the truth. This misinformation is part of the reason why Java programmers go to C++ and use Java-like syntax without understanding the implications of their code.

Onwards we go

But I can't figure out why should we do it this way. I would assume it has to do with efficiency and speed since we get direct access to the memory address. Am I right?

To the contrary, actually. The heap is much slower than the stack, because the stack is very simple compared to the heap. Automatic storage variables (aka stack variables) have their destructors called once they go out of scope. For example:

{
    std::string s;
}
// s is destroyed here

On the other hand, if you use a pointer dynamically allocated, its destructor must be called manually. delete calls this destructor for you.

{
    std::string* s = new std::string;
}
delete s; // destructor called

This has nothing to do with the new syntax prevalent in C# and Java. They are used for completely different purposes.

Benefits of dynamic allocation

1. You don't have to know the size of the array in advance

One of the first problems many C++ programmers run into is that when they are accepting arbitrary input from users, you can only allocate a fixed size for a stack variable. You cannot change the size of arrays either. For example:

char buffer[100];
std::cin >> buffer;
// bad input = buffer overflow

Of course, if you used an std::string instead, std::string internally resizes itself so that shouldn't be a problem. But essentially the solution to this problem is dynamic allocation. You can allocate dynamic memory based on the input of the user, for example:

int * pointer;
std::cout << "How many items do you need?";
std::cin >> n;
pointer = new int[n];

Side note: One mistake many beginners make is the usage of variable length arrays. This is a GNU extension and also one in Clang because they mirror many of GCC's extensions. So the following int arr[n] should not be relied on.

Because the heap is much bigger than the stack, one can arbitrarily allocate/reallocate as much memory as he/she needs, whereas the stack has a limitation.

2. Arrays are not pointers

How is this a benefit you ask? The answer will become clear once you understand the confusion/myth behind arrays and pointers. It is commonly assumed that they are the same, but they are not. This myth comes from the fact that pointers can be subscripted just like arrays and because of arrays decay to pointers at the top level in a function declaration. However, once an array decays to a pointer, the pointer loses its sizeof information. So sizeof(pointer) will give the size of the pointer in bytes, which is usually 8 bytes on a 64-bit system.

You cannot assign to arrays, only initialize them. For example:

int arr[5] = {1, 2, 3, 4, 5}; // initialization 
int arr[] = {1, 2, 3, 4, 5}; // The standard dictates that the size of the array
                             // be given by the amount of members in the initializer  
arr = { 1, 2, 3, 4, 5 }; // ERROR

On the other hand, you can do whatever you want with pointers. Unfortunately, because the distinction between pointers and arrays are hand-waved in Java and C#, beginners don't understand the difference.

3. Polymorphism

Java and C# have facilities that allow you to treat objects as another, for example using the as keyword. So if somebody wanted to treat an Entity object as a Player object, one could do Player player = Entity as Player; This is very useful if you intend to call functions on a homogeneous container that should only apply to a specific type. The functionality can be achieved in a similar fashion below:

std::vector<Base*> vector;
vector.push_back(&square);
vector.push_back(&triangle);
for (auto& e : vector)
{
     auto test = dynamic_cast<Triangle*>(e); // I only care about triangles
     if (!test) // not a triangle
        e.GenericFunction();
     else
        e.TriangleOnlyMagic();
}

So say if only Triangles had a Rotate function, it would be a compiler error if you tried to call it on all objects of the class. Using dynamic_cast, you can simulate the as keyword. To be clear, if a cast fails, it returns an invalid pointer. So !test is essentially a shorthand for checking if test is NULL or an invalid pointer, which means the cast failed.

Benefits of automatic variables

After seeing all the great things dynamic allocation can do, you're probably wondering why wouldn't anyone NOT use dynamic allocation all the time? I already told you one reason, the heap is slow. And if you don't need all that memory, you shouldn't abuse it. So here are some disadvantages in no particular order:

• It is error-prone. Manual memory allocation is dangerous and you are prone to leaks. If you are not proficient at using the debugger or valgrind (a memory leak tool), you may pull your hair out of your head. Luckily RAII idioms and smart pointers alleviate this a bit, but you must be familiar with practices such as The Rule Of Three and The Rule Of Five. It is a lot of information to take in, and beginners who either don't know or don't care will fall into this trap.

• It is not necessary. Unlike Java and C# where it is idiomatic to use the new keyword everywhere, in C++, you should only use it if you need to. The common phrase goes, everything looks like a nail if you have a hammer. Whereas beginners who start with C++ are scared of pointers and learn to use stack variables by habit, Java and C# programmers start by using pointers without understanding it! That is literally stepping off on the wrong foot. You must abandon everything you know because the syntax is one thing, learning the language is another.

1. (N)RVO - Aka, (Named) Return Value Optimization

One optimization many compilers make are things called elision and return value optimization. These things can obviate unnecessary copys which is useful for objects that are very large, such as a vector containing many elements. Normally the common practice is to use pointers to transfer ownership rather than copying the large objects to move them around. This has lead to the inception of move semantics and smart pointers.

If you are using pointers, (N)RVO does NOT occur. It is more beneficial and less error-prone to take advantage of (N)RVO rather than returning or passing pointers if you are worried about optimization. Error leaks can happen if the caller of a function is responsible for deleteing a dynamically allocated object and such. It can be difficult to track the ownership of an object if pointers are being passed around like a hot potato. Just use stack variables because it is simpler and better.

You can definitely do this with vanilla JS like stecb has shown, but I think each is the best answer to the core question concerning how to do it with lodash.

_.each( myObject.options, ( val, key ) => { 
    console.log( key, val ); 
} );

Like JohnnyHK mentioned, there is also the has method which would be helpful for the use case, but from what is originally stated set may be more useful. Let's say you wanted to add something to this object dynamically as you've mentioned:

let dynamicKey = 'someCrazyProperty';
let dynamicValue = 'someCrazyValue';

_.set( myObject.options, dynamicKey, dynamicValue );

That's how I'd do it, based on the original description.

I'm a bit late to the party here i know but,

You could directly access the calls object, which can give you the variables for each call

expect(spy.calls.argsFor(0)[0].value).toBe(expectedValue)

There are two parts of this problem

1) using a parameter that would not alter an url (using params property):

$stateProvider
    .state('login', {
        params: [
            'toStateName',
            'toParamsJson'
        ],
        templateUrl: 'partials/login/Login.html'
    })

2) passing an object as parameter: Well, there is no direct way how to do it now, as every parameter is converted to string (EDIT: since 0.2.13, this is no longer true - you can use objects directly), but you can workaround it by creating the string on your own

toParamsJson = JSON.stringify(toStateParams);

and in target controller deserialize the object again

originalParams = JSON.parse($stateParams.toParamsJson);

Your class MyClass creates a new MyClassToBeTested, instead of using your mock. My article on the Mockito wiki describes two ways of dealing with this.

On a generic note, you can use a combination of ng-if and ng-style incorporate conditional changes with change in background image.

<span ng-if="selectedItem==item.id"
              ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_active.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>
        <span ng-if="selectedItem!=item.id"
              ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_deactivated.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>

You can do it in two different ways.

Option 1: The -eq operator

>$a = "is"
>$b = "fission"
>$c = "is"
>$a -eq $c
True
>$a -eq $b
False

Option 2: The .Equals() method of the string object. Because strings in PowerShell are .Net System.String objects, any method of that object can be called directly.

>$a.equals($b)
False
>$a.equals($c)
True
>$a|get-member -membertype method

List of System.String methods follows.

It looks like the string contains an array with a single MyStok object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:

MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));

You could also deserialize the array into a list of MyStok objects, and take the object at index zero.

var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];

For Maven based projects you need a dependency.

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.38</version>
</dependency>

I will add some short example from me.

The DTO class:

public class SearchDTO {
    private Long id[];

    public Long[] getId() {
        return id;
    }

    public void setId(Long[] id) {
        this.id = id;
    }
    // reflection toString from apache commons
    @Override
    public String toString() {
        return ReflectionToStringBuilder.toString(this, ToStringStyle.SHORT_PREFIX_STYLE);
    }
}

Request mapping inside controller class:

@RequestMapping(value="/handle", method=RequestMethod.GET)
@ResponseBody
public String handleRequest(SearchDTO search) {
    LOG.info("criteria: {}", search);
    return "OK";
}

Query:

http://localhost:8080/app/handle?id=353,234

Result:

[http-apr-8080-exec-7] INFO  c.g.g.r.f.w.ExampleController.handleRequest:59 - criteria: SearchDTO[id={353,234}]

I hope it helps :)

UPDATE / KOTLIN

Because currently I'm working a lot of with Kotlin if someone wants to define similar DTO the class in Kotlin should have the following form:

class SearchDTO {
    var id: Array<Long>? = arrayOf()

    override fun toString(): String {
        // to string implementation
    }
}

With the data class like this one:

data class SearchDTO(var id: Array<Long> = arrayOf())

the Spring (tested in Boot) returns the following error for request mentioned in answer:

"Failed to convert value of type 'java.lang.String[]' to required type 'java.lang.Long[]'; nested exception is java.lang.NumberFormatException: For input string: \"353,234\""

The data class will work only for the following request params form:

http://localhost:8080/handle?id=353&id=234

Be aware of this!

You can use MemberwiseClone

obj myobj2 = (obj)myobj.MemberwiseClone();

The copy is a shallow copy which means the reference properties in the clone are pointing to the same values as the original object but that shouldn't be an issue in your case as the properties in obj are of value types.

If you own the source code, you can also implement ICloneable

If you code in Android, there is SparseArray, mapping integer to object.

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

Minimal version (es6):

Object.entries(obj).reduce((a, [k, v]) => (a[k] = v * v, a), {})

myobj.A

------- or ----------

myobj['A']

will get you 'B'

The syntax you wrote as first is not valid. You can achieve something using the follow:

var map =  {"aaa": "rrr", "bbb": "ppp" /* etc */ };

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

Have a look at using something like

Enum.TryParse

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-sensitive. The return value indicates whether the conversion succeeded.

or

Enum.Parse

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.

I prefer using Hamcrest because it gives much better output in case of a failure

Assert.assertThat(listUnderTest, 
       IsIterableContainingInOrder.contains(expectedList.toArray()));

Instead of reporting

expected true, got false

it will report

expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."

IsIterableContainingInOrder.contain

Hamcrest

According to the Javadoc:

Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items

So the listUnderTest must have the same number of elements and each element must match the expected values in order.

Solution for JUnit 5 for Kotlin!

Example for Hamcrest:

import org.hamcrest.CoreMatchers
import org.hamcrest.MatcherAssert
import org.junit.jupiter.api.Test

class HamcrestAssertionDemo {

    @Test
    fun assertWithHamcrestMatcher() {
        val subClass = SubClass()
        MatcherAssert.assertThat(subClass, CoreMatchers.instanceOf<Any>(BaseClass::class.java))
    }

}

Example for AssertJ:

import org.assertj.core.api.Assertions.assertThat
import org.junit.jupiter.api.Test

class AssertJDemo {

    @Test
    fun assertWithAssertJ() {
        val subClass = SubClass()
        assertThat(subClass).isInstanceOf(BaseClass::class.java)
    }

}

You probably do not want an explicit implementation of IEnumerable<T> (which is what you've shown).

The usual pattern is to use IEnumerable<T>'s GetEnumerator in the explicit implementation of IEnumerable:

class FooCollection : IEnumerable<Foo>, IEnumerable
{
    SomeCollection<Foo> foos;

    // Explicit for IEnumerable because weakly typed collections are Bad
    System.Collections.IEnumerator IEnumerable.GetEnumerator()
    {
        // uses the strongly typed IEnumerable<T> implementation
        return this.GetEnumerator();
    }

    // Normal implementation for IEnumerable<T>
    IEnumerator<Foo> GetEnumerator()
    {
        foreach (Foo foo in this.foos)
        {
            yield return foo;
            //nb: if SomeCollection is not strongly-typed use a cast:
            // yield return (Foo)foo;
            // Or better yet, switch to an internal collection which is
            // strongly-typed. Such as List<T> or T[], your choice.
        }

        // or, as pointed out: return this.foos.GetEnumerator();
    }
}

var myProp = 'prop';
if(myObj.hasOwnProperty(myProp)){
    alert("yes, i have that property");
}

Or

var myProp = 'prop';
if(myProp in myObj){
    alert("yes, i have that property");
}

Or

if('prop' in myObj){
    alert("yes, i have that property");
}

Note that hasOwnProperty doesn't check for inherited properties, whereas in does. For example 'constructor' in myObj is true, but myObj.hasOwnProperty('constructor') is not.

perhaps console.dir is all you need.

http://nodejs.org/api/console.html#console_console_dir_obj

Uses util.inspect on obj and prints resulting string to stdout.

use util option if you need more control.

Dir seems to be very fast.

Sub LoopThroughFiles()
    Dim MyObj As Object, MySource As Object, file As Variant
   file = Dir("c:\testfolder\")
   While (file <> "")
      If InStr(file, "test") > 0 Then
         MsgBox "found " & file
         Exit Sub
      End If
     file = Dir
  Wend
End Sub

Example:

function Foo () { console.log('Foo function'); }_x000D_
var Bar = function () { console.log('Bar function'); };_x000D_
var Abc = function Xyz() { console.log('Abc function'); };_x000D_
_x000D_
var f = new Foo();_x000D_
var b = new Bar();_x000D_
var a = new Abc();_x000D_
_x000D_
console.log('f', f.constructor.name); // -> "Foo"_x000D_
console.log('b', b.constructor.name); // -> "Function"_x000D_
console.log('a', a.constructor.name); // -> "Xyz"

Check out Google's Gson: http://code.google.com/p/google-gson/

From their website:

Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2

You would just need to make a MyType class (renamed, of course) with all the fields in the json string. It might get a little more complicated when you're doing the arrays, if you prefer to do all of the parsing manually (also pretty easy) check out http://www.json.org/ and download the Java source for the Json parser objects.

If you want a copy of the HashMap you need to construct a new one with.

myobjectListB = new HashMap<Integer,myObject>(myobjectListA);

This will create a (shallow) copy of the map.

public class Class1
    {

        private void btn_click(object sender, EventArgs e)
        {
            ServerRequest sr = new ServerRequest();
            sr.Callback += new ServerRequest.CallbackEventHandler(sr_Callback);
            sr.DoRequest("myrequest");
        }

        void sr_Callback(string something)
        {

        }


    }

    public class ServerRequest
    {
        public delegate void CallbackEventHandler(string something);
        public event CallbackEventHandler Callback;   

        public void DoRequest(string request)
        {
            // do stuff....
            if (Callback != null)
                Callback("bla");
        }
    }

Declare the class containing the event:

class MyClass {
    public event EventHandler MyEvent;

    public void Method() {
        OnEvent();
    }

    private void OnEvent() {
        if (MyEvent != null) {
            MyEvent(this, EventArgs.Empty);
        }
    }
}

Use it like this:

MyClass myObject = new MyClass();
myObject.MyEvent += new EventHandler(myObject_MyEvent);
myObject.Method();

It happened that I needed to link a data model of a person with a form, what I did was a direct mapping of the data with the form.

For example if the model had something like:

$scope.model.people.name

The control input of the form:

<input type="text" name="namePeople" model="model.people.name">

That way if you modify the value of the object controller, this will be reflected automatically in the view.

An example where I passed the model is updated from server data is when you ask for a zip code and zip code based on written loads a list of colonies and cities associated with that view, and by default set the first value with the user. And this I worked very well, what does happen, is that angularJS sometimes takes a few seconds to refresh the model, to do this you can put a spinner while displaying the data.

There is no issue in passing back a struct. It will be passed by value

But, what if the struct contains any member which has a address of a local variable

struct emp {
    int id;
    char *name;
};

struct emp get() {
    char *name = "John";

    struct emp e1 = {100, name};

    return (e1);
}

int main() {

    struct emp e2 = get();

    printf("%s\n", e2.name);
}

Now, here e1.name contains a memory address local to the function get(). Once get() returns, the local address for name would have been freed up. SO, in the caller if we try to access that address, it may cause segmentation fault, as we are trying a freed address. That is bad..

Where as the e1.id will be perfectly valid as its value will be copied to e2.id

So, we should always try to avoid returning local memory addresses of a function.

Anything malloced can be returned as and when wanted

.NET already supports basic Json serialization through the System.Runtime.Serialization.Json namespace and the DataContractJsonSerializer class since version 3.5. As the name implies, DataContractJsonSerializer takes into account any data annotations you add to your objects to create the final Json output.

That can be handy if you already have annotated data classes that you want to serialize Json to a stream, as described in How To: Serialize and Deserialize JSON Data. There are limitations but it's good enough and fast enough if you have basic needs and don't want to add Yet Another Library to your project.

The following code serializea a list to the console output stream. As you see it is a bit more verbose than Json.NET and not type-safe (ie no generics)

        var list = new List<string> {"a", "b", "c", "d"};

        using(var output = Console.OpenStandardOutput())                
        {                
            var writer = new DataContractJsonSerializer(typeof (List<string>));
            writer.WriteObject(output,list);
        }

On the other hand, Json.NET provides much better control over how you generate Json. This will come in VERY handy when you have to map javascript-friendly names names to .NET classes, format dates to json etc.

Another option is ServiceStack.Text, part of the ServicStack ... stack, which provides a set of very fast serializers for Json, JSV and CSV.

Well, it is maybe not a really beautiful solution in the code, but it is really beautiful in the interface of your function. And it is also very efficient. It is ideal if the second is more important for you (for example, you are developing a library).

The trick is this:

1. A line A a = b.make(); is internally converted to a constructor of A, i.e. as if you had written A a(b.make());.
2. Now b.make() should result a new class, with a callback function.
3. This whole thing can be fine handled only by classes, without any template.

Here is my minimal example. Check only the main(), as you can see it is simple. The internals aren't.

From the viewpoint of the speed: the size of a Factory::Mediator class is only 2 pointers, which is more that 1 but not more. And this is the only object in the whole thing which is transferred by value.

#include <stdio.h>

class Factory {
  public:
    class Mediator;

    class Result {
      public:
        Result() {
          printf ("Factory::Result::Result()\n");
        };

        Result(Mediator fm) {
          printf ("Factory::Result::Result(Mediator)\n");
          fm.call(this);
        };
    };

    typedef void (*MakeMethod)(Factory* factory, Result* result);

    class Mediator {
      private:
        Factory* factory;
        MakeMethod makeMethod;

      public:
        Mediator(Factory* factory, MakeMethod makeMethod) {
          printf ("Factory::Mediator::Mediator(Factory*, MakeMethod)\n");
          this->factory = factory;
          this->makeMethod = makeMethod;
        };

        void call(Result* result) {
          printf ("Factory::Mediator::call(Result*)\n");
          (*makeMethod)(factory, result);
        };
    };
};

class A;

class B : private Factory {
  private:
    int v;

  public:
    B(int v) {
      printf ("B::B()\n");
      this->v = v;
    };

    int getV() const {
      printf ("B::getV()\n");
      return v;
    };

    static void makeCb(Factory* f, Factory::Result* a);

    Factory::Mediator make() {
      printf ("Factory::Mediator B::make()\n");
      return Factory::Mediator(static_cast<Factory*>(this), &B::makeCb);
    };
};

class A : private Factory::Result {
  friend class B;

  private:
    int v;

  public:
    A() {
      printf ("A::A()\n");
      v = 0;
    };

    A(Factory::Mediator fm) : Factory::Result(fm) {
      printf ("A::A(Factory::Mediator)\n");
    };

    int getV() const {
      printf ("A::getV()\n");
      return v;
    };

    void setV(int v) {
      printf ("A::setV(%i)\n", v);
      this->v = v;
    };
};

void B::makeCb(Factory* f, Factory::Result* r) {
      printf ("B::makeCb(Factory*, Factory::Result*)\n");
      B* b = static_cast<B*>(f);
      A* a = static_cast<A*>(r);
      a->setV(b->getV()+1);
    };

int main(int argc, char **argv) {
  B b(42);
  A a = b.make();
  printf ("a.v = %i\n", a.getV());
  return 0;
}

It could be used as a wrapper function for returning a reference to a private constant data type. For example in a linked list you have the constants tail and head, and if you want to determine if a node is a tail or head node, then you can compare it with the value returned by that function.

Though any optimizer would most likely optimize it out anyway...

You can use such trick:

myObject = new ArrayList<Object>(myTempObject);

or use

myObject = (ArrayList<Object>)myTempObject.clone();

You can get some information about clone() method here

But you should remember, that all these ways will give you a copy of your List, not all of its elements. So if you change one of the elements in your copied List, it will also be changed in your original List.

The normal solution to this is to pass an instance of the context to the class as you create it, or after it is first created but before you need to use the context.

Another solution is to create an Application object with a static method to access the application context although that couples the Droid object fairly tightly into the code.

Edit, examples added

Either modify the Droid class to be something like this

 public Droid(Context context,int x, int y) {
    this.bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.birdpic);
    this.x = x;
    this.y = y;
    }   

Or create an Application something like this:

public class App extends android.app.Application
{
    private static App mApp = null;
    /* (non-Javadoc)
     * @see android.app.Application#onCreate()
     */
    @Override
    public void onCreate()
    {
        super.onCreate();
        mApp = this;
    }
    public static Context context()
    {
        return mApp.getApplicationContext();
    }
}

And call App.context() wherever you need a context - note however that not all functions are available on an application context, some are only available on an activity context but it will certainly do with your need for getResources().

Please note that you'll need to add android:name to your application definition in your manifest, something like this:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:name=".App" >

    function ArrayToObject( arr ) {
    var obj = {};
    for (var i = 0; i < arr.length; ++i){
        var name = arr[i].name;
        var value = arr[i].value;
        obj[name] = arr[i].value;
    }
    return obj;
    }

      var form_data = $('#my_form').serializeArray();
            form_data = ArrayToObject( form_data );
            form_data.action = event.target.id;
            form_data.target = event.target.dataset.event;
            console.log( form_data );
            $.post("/api/v1/control/", form_data, function( response ){
                console.log(response);
            }).done(function( response ) {
                $('#message_box').html('SUCCESS');
            })
            .fail(function(  ) { $('#message_box').html('FAIL'); })
            .always(function(  ) { /*$('#message_box').html('SUCCESS');*/ });

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

Actually all answers are wrong

Easy: foo.[0]filename

x = [];
for( var i in myObj ) {
    x[i] = myObj[i];
}

I modified rushidesai1's answer to include a working example.

You could override the equals() method, with title, author, url and description. (and the hashCode() since if you override one you should override the other). Then use a HashSet of type <blog>.

The answer from @edutesoy points to the documentation of PowerMockito and mentions constructor mocking as a hint but doesn't mention how to apply that to the current problem in the question.

Here is a solution based on that. Taking the code from the question:

public class MyClass {
    void method1 {
        MyObject obj1 = new MyObject();
        obj1.method1();
    }
}

The following test will create a mock of the MyObject instance class via preparing the class that instantiates it (in this example I am calling it MyClass) with PowerMock and letting PowerMockito to stub the constructor of MyObject class, then letting you stub the MyObject instance method1() call:

@RunWith(PowerMockRunner.class)
@PrepareForTest(MyClass.class)
public class MyClassTest {
    @Test
    public void testMethod1() {      
        MyObject myObjectMock = mock(MyObject.class);
        when(myObjectMock.method1()).thenReturn(<whatever you want to return>);   
        PowerMockito.whenNew(MyObject.class).withNoArguments().thenReturn(myObjectMock);
        
        MyClass objectTested = new MyClass();
        objectTested.method1();
        
        ... // your assertions or verification here 
    }
}

With that your internal method1() call will return what you want.

If you like the one-liners you can make the code shorter by creating the mock and the stub inline:

MyObject myObjectMock = when(mock(MyObject.class).method1()).thenReturn(<whatever you want>).getMock();   

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

myObj[prop] = value;

That should work. You mixed up the name of the variable and its value. But indexing an object with strings to get at its properties works fine in JavaScript.

If you are using WebApi, HttpResponseMessage is a more elegant way to do it

public HttpResponseMessage Get()
{
    return Request.CreateResponse(HttpStatusCode.OK, ListOfMyObject);
}

I had this problem inconsistently between different platforms, as I got JSON as String from Mapper and did the writing myself. Sometimes it went into file as ansi and other times correctly as UTF8. I switched to

mapper.writeValue(file, data);

letting Mapper do the file operations, and it started working fine.

It isn't quite out of the box but CXF does support JSON bindings to rest services. See cxf jax-rs json docs here. You'll still need to do some minimal configuration to have the provider available and you need to be familiar with jettison if you want to have more control over how the JSON is formed.

EDIT: Per comment request, here is some code. I don't have a lot of experience with this but the following code worked as an example in a quick test system.

//TestApi parts
@GET
@Path ( "test" )
@Produces ( "application/json" )
public Demo getDemo () {
    Demo d = new Demo ();
    d.id = 1;
    d.name = "test";
    return d;
}

//client config for a TestApi interface
List providers = new ArrayList ();
JSONProvider jsonProvider = new JSONProvider ();
Map<String, String> map = new HashMap<String, String> ();
map.put ( "http://www.myserviceapi.com", "myapi" );
jsonProvider.setNamespaceMap ( map );
providers.add ( jsonProvider );
TestApi proxy = JAXRSClientFactory.create ( url, TestApi.class, 
    providers, true );

Demo d = proxy.getDemo ();
if ( d != null ) {
    System.out.println ( d.id + ":" + d.name );
}

//the Demo class
@XmlRootElement ( name = "demo", namespace = "http://www.myserviceapi.com" )
@XmlType ( name = "demo", namespace = "http://www.myserviceapi.com", 
    propOrder = { "name", "id" } )
@XmlAccessorType ( XmlAccessType.FIELD )
public class Demo {

    public String name;
    public int id;
}

Notes:

1. The providers list is where you code configure the JSON provider on the client. In particular, you see the namespace mapping. This needs to match what is on your server side configuration. I don't know much about Jettison options so I'm not much help on manipulating all of the various knobs for controlling the marshalling process.
2. Jettison in CXF works by marshalling XML from a JAXB provider into JSON. So you have to ensure that the payload objects are all marked up (or otherwise configured) to marshall as application/xml before you can have them marshall as JSON. If you know of a way around this (other than writing your own message body writer), I'd love to hear about it.
3. I use spring on the server so my configuration there is all xml stuff. Essentially, you need to go through the same process to add the JSONProvider to the service with the same namespace configuration. Don't have code for that handy but I imagine it will mirror the client side fairly well.

This is a bit dirty as an example but will hopefully get you going.

Edit2: An example of a message body writer that is based on xstream to avoid jaxb.

@Produces ( "application/json" )
@Consumes ( "application/json" )
@Provider
public class XstreamJsonProvider implements MessageBodyReader<Object>,
    MessageBodyWriter<Object> {

@Override
public boolean isWriteable ( Class<?> type, Type genericType, 
    Annotation[] annotations, MediaType mediaType ) {
    return MediaType.APPLICATION_JSON_TYPE.equals ( mediaType ) 
        && type.equals ( Demo.class );
}

@Override
public long getSize ( Object t, Class<?> type, Type genericType, 
    Annotation[] annotations, MediaType mediaType ) {
    // I'm being lazy - should compute the actual size
    return -1;
}

@Override
public void writeTo ( Object t, Class<?> type, Type genericType, 
    Annotation[] annotations, MediaType mediaType, 
    MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream ) 
    throws IOException, WebApplicationException {
    // deal with thread safe use of xstream, etc.
    XStream xstream = new XStream ( new JettisonMappedXmlDriver () );
    xstream.setMode ( XStream.NO_REFERENCES );
    // add safer encoding, error handling, etc.
    xstream.toXML ( t, entityStream );
}

@Override
public boolean isReadable ( Class<?> type, Type genericType, 
    Annotation[] annotations, MediaType mediaType ) {
    return MediaType.APPLICATION_JSON_TYPE.equals ( mediaType ) 
        && type.equals ( Demo.class );
}

@Override
public Object readFrom ( Class<Object> type, Type genericType, 
    Annotation[] annotations, MediaType mediaType, 
    MultivaluedMap<String, String> httpHeaders, InputStream entityStream ) 
    throws IOException, WebApplicationException {
    // add error handling, etc.
    XStream xstream = new XStream ( new JettisonMappedXmlDriver () );
    return xstream.fromXML ( entityStream );
}
}

//now your client just needs this
List providers = new ArrayList ();
XstreamJsonProvider jsonProvider = new XstreamJsonProvider ();
providers.add ( jsonProvider );
TestApi proxy = JAXRSClientFactory.create ( url, TestApi.class, 
    providers, true );

Demo d = proxy.getDemo ();
if ( d != null ) {
    System.out.println ( d.id + ":" + d.name );
}

The sample code is missing the parts for robust media type support, error handling, thread safety, etc. But, it ought to get you around the jaxb issue with minimal code.

EDIT 3 - sample server side configuration As I said before, my server side is spring configured. Here is a sample configuration that works to wire in the provider:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/jaxrs"
xmlns:cxf="http://cxf.apache.org/core"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
    http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

<import resource="classpath:META-INF/cxf/cxf.xml" />

<jaxrs:server id="TestApi">
    <jaxrs:serviceBeans>
        <ref bean="testApi" />
    </jaxrs:serviceBeans>
    <jaxrs:providers>
        <bean id="xstreamJsonProvider" class="webtests.rest.XstreamJsonProvider" />
    </jaxrs:providers>
</jaxrs:server>

<bean id="testApi" class="webtests.rest.TestApi">
</bean>

</beans>

I have also noted that in the latest rev of cxf that I'm using there is a difference in the media types, so the example above on the xstream message body reader/writer needs a quick modification where isWritable/isReadable change to:

return MediaType.APPLICATION_JSON_TYPE.getType ().equals ( mediaType.getType () )
    && MediaType.APPLICATION_JSON_TYPE.getSubtype ().equals ( mediaType.getSubtype () )
    && type.equals ( Demo.class );

EDIT 4 - non-spring configuration Using your servlet container of choice, configure

org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet

with at least 2 init params of:

jaxrs.serviceClasses
jaxrs.providers

where the serviceClasses is a space separated list of the service implementations you want bound, such as the TestApi mentioned above and the providers is a space separated list of message body providers, such as the XstreamJsonProvider mentioned above. In tomcat you might add the following to web.xml:

<servlet>
    <servlet-name>cxfservlet</servlet-name>
    <servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
    <init-param>
        <param-name>jaxrs.serviceClasses</param-name>

    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

That is pretty much the quickest way to run it without spring. If you are not using a servlet container, you would need to configure the JAXRSServerFactoryBean.setProviders with an instance of XstreamJsonProvider and set the service implementation via the JAXRSServerFactoryBean.setResourceProvider method. Check the CXFNonSpringJaxrsServlet.init method to see how they do it when setup in a servlet container.

That ought to get you going no matter your scenario.

This question has already been answered perfectly by other people, if you want to do it on your own.

If you prefer to encapsulate or hide away most of the low-level parceling code, you might consider using some of the code I wrote some time ago for simplifying handling of parcelables.

Writing to a parcel is as easy as:

parcelValues(dest, name, maxSpeed, weight, wheels, color, isDriving);

where color is an enum and isDriving is a boolean, for example.

Reading from a parcel is also not much harder:

color = (CarColor)unparcelValue(CarColor.class.getClassLoader());
isDriving = (Boolean)unparcelValue();

Just take a look at the "ParceldroidExample" I added to the project.

Finally, it also keeps the CREATOR initializer short:

public static final Parcelable.Creator<Car> CREATOR =
    Parceldroid.getCreatorForClass(Car.class);

If you had two Strings and compared them using == by calling the getClass() method on them, it would return true. What you get is a reference on the same object.

This is because they are both references on the same class object. This is true for all classes in a java application. Java only loads the class once, so you have only one instance of a given class at a given time.

String hello  = "Hello";
String world = "world";

if (hello.getClass() == world.getClass()) {
    System.out.println("true");
} // prints true

If using Newtonsoft.Json:

using Newtonsoft.Json;
using System.Net.Http;
using System.Text;

public static class Extensions
{
    public static StringContent AsJson(this object o)
        => new StringContent(JsonConvert.SerializeObject(o), Encoding.UTF8, "application/json");
}

Example:

var httpClient = new HttpClient();
var url = "https://www.duolingo.com/2016-04-13/login?fields=";
var data = new { identifier = "username", password = "password" };
var result = await httpClient.PostAsync(url, data.AsJson())

One of the challenges I had with the answers is that it assumed that the object was a single level. For example,

const testObj = { testKey: 'testValue' }
const refString = 'testKey';
const refObj = testObj[refString];

works fine, but

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testKey.level2Key';
const refObj = testObj[refString];

does not work.

What I ended up doing was building a function to access multi-level objects:

objVar(str) {
    let obj = this;
    const parts = str.split('.');
    for (let p of parts) {
        obj = obj[p];
    }
    return obj;
}

In the second scenario, then, I can pass the string to this function to get back the object I'm looking for:

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testObj.testKey.level2Key';
const refObj = objVar[refString];

What Ed Guiness suggested is really a performance booster , I had a query like this

select * from table where id in (id1,id2.........long list)

what i did :

DECLARE @temp table(
            ID  int
            )
insert into @temp 
select * from dbo.fnSplitter('#idlist#')

Then inner joined the temp with main table :

select * from table inner join temp on temp.id = table.id

And performance improved drastically.

Maybe not the most efficient way. But you could convert the list into a vector.

#include <list>
#include <vector>

list<Object> myList;

vector<Object> myVector(myList.begin(), myList.end());

Then access the vector using the [x] operator.

auto x = MyVector[0];

You could put that in a helper function:

#include <memory>
#include <vector>
#include <list>

template<class T>
shared_ptr<vector<T>> 
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
        new vector<string>(List.begin(), List.end()) }
return Vector;
}

Then use the helper funciton like this:

auto MyVector = ListToVector(Object);
auto x = MyVector[0];

The current object is explicitly passed to the method as the first parameter. self is the conventional name. You can call it anything you want but it is strongly advised that you stick with this convention to avoid confusion.

I needeed to solve very similar problem, which is configuring Jackson Mapper to "Do not serialize null values for Christ's sake!!!".

I didn't want to leave fancy mvc:annotation-driven tag, so I found, how to configure Jackson's ObjectMapper without removing mvc:annotation-driven and adding not really fancy ContentNegotiatingViewResolver.

The beautiful thing is that you don't have to write any Java code yourself!

And here is the XML configuration (don't be confused with different namespaces of Jackson classes, I simply used new Jakson 2.x library ... the same should also work with Jackson 1.x libraries):

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">
                <bean class="com.fasterxml.jackson.databind.ObjectMapper">
                    <property name="serializationInclusion">
                        <value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</value>
                    </property>
                </bean>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

Update: This got fixed in C# 7.0 with pattern matching

switch (MyObj)
    case Type1 t1: 
    case Type2 t2:
    case Type3 t3:

Old answer:

It is a hole in C#'s game, no silver bullet yet.

You should google on the 'visitor pattern' but it might be a little heavy for you but still something you should know about.

Here's another take on the matter using Linq: http://community.bartdesmet.net/blogs/bart/archive/2008/03/30/a-functional-c-type-switch.aspx

Otherwise something along these lines could help

// nasty..
switch(MyObj.GetType.ToString()){
  case "Type1": etc
}

// clumsy...
if myObj  is Type1 then
if myObj is Type2 then

etc.

I am the original poster and I accepted the above answer by DGH without having first used it in the code.

Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).

I thought it was worth posting the tweak here for the benefit of others:

    try:
        a = Application("abcdef", "")
    except pySourceAidExceptions.PathIsNotAValidOne:
        pass
    except:
        self.assertTrue(False)

What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.

I believe that using the above code (based heavily on DGH's answer) will do that.

These solutions work too.

// Solution One
function removeProperty(obj, prop) {
  var bool;
  var keys = Object.keys(obj);
  for (var i = 0; i < keys.length; i++) {
    if (keys[i] === prop) {
      delete obj[prop];
      bool = true;
    } 
  }
  return Boolean(bool);
}


//Solution two
function removeProperty(obj, prop) {
  var bool;
  if (obj.hasOwnProperty(prop)) {
      bool = true;
      delete obj[prop];
  }
  return Boolean(bool);
}

Just use plain objects:

var map = { key1: "value1", key2: "value2" }
function get(k){
  return map[k];
}

The following function can be copied to any object to add an XML save function using the System.Xml namespace.

/// <summary>
/// Saves to an xml file
/// </summary>
/// <param name="FileName">File path of the new xml file</param>
public void Save(string FileName)
{
    using (var writer = new System.IO.StreamWriter(FileName))
    {
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();
    }
}

To create the object from the saved file, add the following function and replace [ObjectType] with the object type to be created.

/// <summary>
/// Load an object from an xml file
/// </summary>
/// <param name="FileName">Xml file name</param>
/// <returns>The object created from the xml file</returns>
public static [ObjectType] Load(string FileName)
{
    using (var stream = System.IO.File.OpenRead(FileName))
    {
        var serializer = new XmlSerializer(typeof([ObjectType]));
        return serializer.Deserialize(stream) as [ObjectType];
    }
}

I might get beat up for my answer but here goes anyway:

I would simply write

string s = ""
if (myObj != null) {
   x = myObj.toString();
}

Is there a payoff in terms of performance for using the ternary operator? I don't know off the top of my head.

And clearly, as someone above mentioned, you can put this behavior into a method such as safeString(myObj) that allows for reuse.

Not sure if I am late to the party but I found this nice example that overrides the JSONObject constructor and makes sure that the JSON data are output in the same way as they are added. Behind the scenes JSONObject uses the MAP and MAP does not guarantee the order hence we need to override it to make sure we are receiving our JSON as per our order.

If you add this to your JSONObject then the resulting JSON would be in the same order as you have created it.

import java.io.IOException;
import java.lang.reflect.Field;
import java.util.LinkedHashMap;
import org.json.JSONObject;
import lombok.extern.java.Log;

@Log
public class JSONOrder {

    public static void main(String[] args) throws IOException {

        JSONObject jsontest = new JSONObject();
        try {
            Field changeMap = jsonEvent.getClass().getDeclaredField("map");
            changeMap.setAccessible(true);
            changeMap.set(jsonEvent, new LinkedHashMap<>());
            changeMap.setAccessible(false);
        } catch (IllegalAccessException | NoSuchFieldException e) {
            log.info(e.getMessage());
        }
        jsontest.put("one", "I should be first");
        jsonEvent.put("two", "I should be second");
        jsonEvent.put("third", "I should be third");
        System.out.println(jsonEvent);
    }
}

This is very good discussion. I had one of those moments when I wished or lets say hoped (successfully that I might add) to reinvent the wheel be it a square one. Any ways above is good discussion, so any one coming here looking for what is the difference between Element property and attribute. here is my penny worth and I did have to find it out hard way. I would keep it simple so no extraordinary tech jargon.

suppose we have a variable calls 'A'. what we are used to is as following.

Below will throw an error because simply it put its is kind of object that can only have one property and that is singular left hand side = singular right hand side object. Every thing else is ignored and tossed out in bin.

let A = 'f';
A.b =2;
console.log(A.b);

who has decided that it has to be singular = singular. People who make JavaScript and html standards and thats how engines work.

Lets change the example.

let A = {};
A.b =2;
console.log(A.b);

This time it works ..... because we have explicitly told it so and who decided we can tell it in this case but not in previous case. Again people who make JavaScript and html standards.

I hope we are on this lets complicate it further

let A = {};
A.attribute ={};
A.attribute.b=5;
console.log(A.attribute.b); // will work

console.log(A.b); // will not work

What we have done is tree of sorts level 1 then sub levels of non-singular object. Unless you know what is where and and call it so it will work else no.

This is what goes on with HTMLDOM when its parsed and painted a DOm tree is created for each and every HTML ELEMENT. Each has level of properties per say. Some are predefined and some are not. This is where ID and VALUE bits come on. Behind the scene they are mapped on 1:1 between level 1 property and sun level property aka attributes. Thus changing one changes the other. This is were object getter ans setter scheme of things plays role.

let A = {
attribute :{
id:'',
value:''
},
getAttributes: function (n) {
    return this.attribute[n];
  },
setAttributes: function (n,nn){
this.attribute[n] = nn;
if(this[n]) this[n] = nn;
},
id:'',
value:''
};



A.id = 5;
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('id',7)
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('ids',7)
console.log(A.ids);
console.log(A.getAttributes('ids'));

A.idsss=7;
console.log(A.idsss);
console.log(A.getAttributes('idsss'));

This is the point as shown above ELEMENTS has another set of so called property list attributes and it has its own main properties. there some predefined properties between the two and are mapped as 1:1 e.g. ID is common to every one but value is not nor is src. when the parser reaches that point it simply pulls up dictionary as to what to when such and such are present.

All elements have properties and attributes and some of the items between them are common. What is common in one is not common in another.

In old days of HTML3 and what not we worked with html first then on to JS. Now days its other way around and so has using inline onlclick become such an abomination. Things have moved forward in HTML5 where there are many property lists accessible as collection e.g. class, style. In old days color was a property now that is moved to css for handling is no longer valid attribute.

Element.attributes is sub property list with in Element property.

Unless you could change the getter and setter of Element property which is almost high unlikely as it would break hell on all functionality is usually not writable off the bat just because we defined something as A.item does not necessarily mean Js engine will also run another line of function to add it into Element.attributes.item.

I hope this gives some headway clarification as to what is what. Just for the sake of this I tried Element.prototype.setAttribute with custom function it just broke loose whole thing all together, as it overrode native bunch of functions that set attribute function was playing behind the scene.

Here is a thing I made for myself to clear out how things work. I guess others too can find this concrete example useful:

doit().then(function() { log('Now finally done!') });_x000D_
log('---- But notice where this ends up!');_x000D_
_x000D_
// For pedagogical reasons I originally wrote the following doit()-function so that _x000D_
// it was clear that it is a promise. That way wasn't really a normal way to do _x000D_
// it though, and therefore Slikts edited my answer. I therefore now want to remind _x000D_
// you here that the return value of the following function is a promise, because _x000D_
// it is an async function (every async function returns a promise). _x000D_
async function doit() {_x000D_
  log('Calling someTimeConsumingThing');_x000D_
  await someTimeConsumingThing();_x000D_
  log('Ready with someTimeConsumingThing');_x000D_
}_x000D_
_x000D_
function someTimeConsumingThing() {_x000D_
  return new Promise(function(resolve,reject) {_x000D_
    setTimeout(resolve, 2000);_x000D_
  })_x000D_
}_x000D_
_x000D_
function log(txt) {_x000D_
  document.getElementById('msg').innerHTML += txt + '<br>'_x000D_
}

<div id='msg'></div>

If you're not sure whether the object has been disposed or not, you should call the Dispose method itself rather than methods such as Close. While the framework doesn't guarantee that the Dispose method must run without exceptions even if the object had previously been disposed, it's a common pattern and to my knowledge implemented on all disposable objects in the framework.

The typical pattern for Dispose, as per Microsoft:

public void Dispose() 
{
    Dispose(true);

    // Use SupressFinalize in case a subclass
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);      
}

protected virtual void Dispose(bool disposing)
{
    // If you need thread safety, use a lock around these 
    // operations, as well as in your methods that use the resource.
    if (!_disposed)
    {
        if (disposing) {
            if (_resource != null)
                _resource.Dispose();
                Console.WriteLine("Object disposed.");
        }

        // Indicate that the instance has been disposed.
        _resource = null;
        _disposed = true;   
    }
}

Notice the check on _disposed. If you were to call a Dispose method implementing this pattern, you could call Dispose as many times as you wanted without hitting exceptions.

Edit: I had first said:

What's inelegant about the dictionary solution. It seems perfectly elegant to me, esp since you only need to set the comparator in creation of the dictionary.

Of course though, it is inelegant to use something as a key when it's also the value.

Therefore I would use a HashSet. If later operations required indexing, I'd create a list from it when the Adding was done, otherwise, just use the hashset.

What do you mean by an "anonymous object?" myObj is not anonymous since you've assigned an object literal to a variable. You can just test this:

if (typeof myObj.prop2 === 'function')
{
    // do whatever
}

Just stumble upon this old post and thought of adding my two cents. Generally, if I am in doubt, I quickly use the GetHashCode() method on any object to check the identities. So for above -

    public class MyObject
{
    public int SimpleInt { get; set; }
}


class Program
{

    public static void RunChangeList()
    {
        var objs = new List<MyObject>() { new MyObject() { SimpleInt = 0 } };
        Console.WriteLine("objs: {0}", objs.GetHashCode());
        Console.WriteLine("objs[0]: {0}", objs[0].GetHashCode());
        var whatInt = ChangeToList(objs);
        Console.WriteLine("whatInt: {0}", whatInt.GetHashCode());
    }

    public static int ChangeToList(List<MyObject> objects)
    {
        Console.WriteLine("objects: {0}", objects.GetHashCode());
        Console.WriteLine("objects[0]: {0}", objects[0].GetHashCode());
        var objectList = objects.ToList();
        Console.WriteLine("objectList: {0}", objectList.GetHashCode());
        Console.WriteLine("objectList[0]: {0}", objectList[0].GetHashCode());
        objectList[0].SimpleInt = 5;
        return objects[0].SimpleInt;

    }

    private static void Main(string[] args)
    {
        RunChangeList();
        Console.ReadLine();
    }

And answer on my machine -

• objs: 45653674
• objs[0]: 41149443
• objects: 45653674
• objects[0]: 41149443
• objectList: 39785641
• objectList[0]: 41149443
• whatInt: 5

So essentially the object that list carries remain the same in above code. Hope the approach helps.

This is one of the tricky parts of Javascript, but also one of its core features. A variable declared with var "begins its life" right where you declare it. If you leave out the var, it's like you're talking about a variable that you have used before.

var foo = 'first time use';
foo = 'second time use';

With regards to scope, it is not true that variables automatically become global. Rather, Javascript will traverse up the scope chain to see if you have used the variable before. If it finds an instance of a variable of the same name used before, it'll use that and whatever scope it was declared in. If it doesn't encounter the variable anywhere it'll eventually hit the global object (window in a browser) and will attach the variable to it.

var foo = "I'm global";
var bar = "So am I";

function () {
    var foo = "I'm local, the previous 'foo' didn't notice a thing";
    var baz = "I'm local, too";

    function () {
        var foo = "I'm even more local, all three 'foos' have different values";
        baz = "I just changed 'baz' one scope higher, but it's still not global";
        bar = "I just changed the global 'bar' variable";
        xyz = "I just created a new global variable";
    }
}

This behavior is really powerful when used with nested functions and callbacks. Learning about what functions are and how scope works is the most important thing in Javascript.

public class MyObject implements Cloneable, Serializable{   

    @Override
    @SuppressWarnings(value = "unchecked")
    protected MyObject clone(){
        ObjectOutputStream oos = null;
        ObjectInputStream ois = null;
        try {
            ByteArrayOutputStream bOs = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(bOs);
            oos.writeObject(this);
            ois = new ObjectInputStream(new ByteArrayInputStream(bOs.toByteArray()));
            return  (MyObject)ois.readObject();

        } catch (Exception e) {
            //Some seriouse error :< //
            return null;
        }finally {
            if (oos != null)
                try {
                    oos.close();
                } catch (IOException e) {

                }
            if (ois != null)
                try {
                    ois.close();
                } catch (IOException e) {

                }
        }
    }
}

Oneliner:

obj = (function(attr, val){ var a = {}; a[attr]=val; return a; })('hash', 5);

Or:

attr = 'hash';
val = 5;
var obj = (obj={}, obj[attr]=val, obj);

Anything shorter?

The debugger is making it simpler, because you don't want to step through the actual code that the compiler creates.

If the switch contains more than five items, it's implemented using a lookup table or hash table, otherwise it's implemeneted using an if..else.

See the closely related question is “else if” faster than “switch() case” ?.

Other languages than C# will of course implement it more or less differently, but a switch is generally more efficient.

Kinda late to the party but I asked myself this question and saw this then thought of an answer. I don't know if someone already posted this. But essentially, I've noticed that all iterable types have __getitem__() in their dict. This is how you would check if an object was an iterable without even trying. (Pun intended)

def is_attr(arg):
    return '__getitem__' in dir(arg)

When serialising an XML document to a .NET string, the encoding must be set to UTF-16. Strings are stored as UTF-16 internally, so this is the only encoding that makes sense. If you want to store data in a different encoding, you use a byte array instead.

SQL Server works on a similar principle; any string passed into an xml column must be encoded as UTF-16. SQL Server will reject any string where the XML declaration does not specify UTF-16. If the XML declaration is not present, then the XML standard requires that it default to UTF-8, so SQL Server will reject that as well.

Bearing this in mind, here are some utility methods for doing the conversion.

public static string Serialize<T>(T value) {

    if(value == null) {
        return null;
    }

    XmlSerializer serializer = new XmlSerializer(typeof(T));

    XmlWriterSettings settings = new XmlWriterSettings()
    {
        Encoding = new UnicodeEncoding(false, false), // no BOM in a .NET string
        Indent = false,
        OmitXmlDeclaration = false
    };

    using(StringWriter textWriter = new StringWriter()) {
        using(XmlWriter xmlWriter = XmlWriter.Create(textWriter, settings)) {
            serializer.Serialize(xmlWriter, value);
        }
        return textWriter.ToString();
    }
}

public static T Deserialize<T>(string xml) {

    if(string.IsNullOrEmpty(xml)) {
        return default(T);
    }

    XmlSerializer serializer = new XmlSerializer(typeof(T));

    XmlReaderSettings settings = new XmlReaderSettings();
    // No settings need modifying here

    using(StringReader textReader = new StringReader(xml)) {
        using(XmlReader xmlReader = XmlReader.Create(textReader, settings)) {
            return (T) serializer.Deserialize(xmlReader);
        }
    }
}

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

If you want the serialized data to be really compact, you can write serialization methods yourself. That way you will have a minimum of overhead.

Example:

public class MyClass {

   public int Id { get; set; }
   public string Name { get; set; }

   public byte[] Serialize() {
      using (MemoryStream m = new MemoryStream()) {

There's a fantastic blogpost that covers this here: Comparing Dates and Datetimes in the Django ORM

The best solution posted for Django>1.7,<1.9 is to register a transform:

from django.db import models

class MySQLDatetimeDate(models.Transform):
    """
    This implements a custom SQL lookup when using `__date` with datetimes.
    To enable filtering on datetimes that fall on a given date, import
    this transform and register it with the DateTimeField.
    """
    lookup_name = 'date'

    def as_sql(self, compiler, connection):
        lhs, params = compiler.compile(self.lhs)
        return 'DATE({})'.format(lhs), params

    @property
    def output_field(self):
        return models.DateField()

Then you can use it in your filters like this:

Foo.objects.filter(created_on__date=date)

EDIT

This solution is definitely back end dependent. From the article:

Of course, this implementation relies on your particular flavor of SQL having a DATE() function. MySQL does. So does SQLite. On the other hand, I haven’t worked with PostgreSQL personally, but some googling leads me to believe that it does not have a DATE() function. So an implementation this simple seems like it will necessarily be somewhat backend-dependent.

Simple:

delete myObj.test.key1;

Try this

ifnull(X,Y)  

e.g

select ifnull(InfoDetail,'') InfoDetail; -- this will replace null with ''
select ifnull(NULL,'THIS IS NULL');-- More clearly....

The ifnull() function returns a copy of its first non-NULL argument, or NULL if both arguments are NULL. Ifnull() must have exactly 2 arguments. The ifnull() function is equivalent to coalesce() with two arguments.

This is pretty old, but I ran across this question via Google, so perhaps this solution might be useful to others.

function GetObjectName(myObject){
    var objectName=JSON.stringify(myObject).match(/"(.*?)"/)[1];
    return objectName;
}

It just uses the browser's JSON parser and regex without cluttering up the DOM or your object too much.

I am listing the difference in each of the casting ways. What a particular type of casting handles and it doesn't?

    // object to int
    // does not handle null
    // does not handle NAN ("102art54")
    // convert value to integar
    int intObj = (int)obj;

    // handles only null or number
    int? nullableIntObj = (int?)obj; // null
    Nullable<int> nullableIntObj1 = (Nullable<int>)obj; // null

   // best way for casting from object to nullable int
   // handles null 
   // handles other datatypes gives null("sadfsdf") // result null
    int? nullableIntObj2 = obj as int?; 

    // string to int 
    // does not handle null( throws exception)
    // does not string NAN ("102art54") (throws exception)
    // converts string to int ("26236")
    // accepts string value
    int iVal3 = int.Parse("10120"); // throws exception value cannot be null;

    // handles null converts null to 0
    // does not handle NAN ("102art54") (throws exception)
    // converts obj to int ("26236")
    int val4 = Convert.ToInt32("10120"); 

    // handle null converts null to 0
    // handle NAN ("101art54") converts null to 0
    // convert string to int ("26236")
    int number;

    bool result = int.TryParse(value, out number);

    if (result)
    {
        // converted value
    }
    else
    {
        // number o/p = 0
    }

There are a bunch of reasons here: http://macresearch.org/difference-between-alloc-init-and-new

Some selected ones are:

• new doesn't support custom initializers (like initWithString)
• alloc-init is more explicit than new

General opinion seems to be that you should use whatever you're comfortable with.

I had this problem with a ComboBox displaying a list of colors ( List<Brush> ).
Selecting a color was possible but it wasnt displayed when the selection closed (although the property was changed!)

The fix was overwriting the Equals(object obj) method for the type selected in the ComboBox (Brush), which wasnt simple because Brush is sealed. So i wrote a class EqualityBrush containing a Brush and implementing Equals:

public class EqualityBrush
{
    public SolidColorBrush Brush { get; set; }

    public override bool Equals(object o)
    {
        if (o is EqualityBrush)
        {
            SolidColorBrush b = ((EqualityBrush)o).Brush;
            return b.Color.R == this.Brush.Color.R && b.Color.G == this.Brush.Color.G && b.Color.B == this.Brush.Color.B;
        }
        else
            return false;
    }
}

Using a List of my new EqualityBrush class instead of normal Brush class fixed the problem!

My Combobox XAML looks like this:

<ComboBox ItemsSource="{Binding BuerkertBrushes}" SelectedItem="{Binding Brush, Mode=TwoWay}" Width="40">
    <ComboBox.Resources>
        <DataTemplate DataType="{x:Type tree:EqualityBrush}">
            <Rectangle Width="20" Height="12" Fill="{Binding Brush}"/>
        </DataTemplate>
    </ComboBox.Resources>
</ComboBox>

Remember that my "Brush"-Property in the ViewModel now has to be of Type EqualityBrush!

As long as your vector remains in global scope you can return:

&(*iterator)

I'll caution you that this is pretty dangerous in general. If your vector is ever moved out of global scope and is destructed, any pointers to myObject become invalid. If you're writing these functions as part of a larger project, returning a non-const pointer could lead someone to delete the return value. This will have undefined, and catastrophic, effects on the application.

I'd rewrite this as:

myObject myFunction(const vector<myObject>& objects)
{
    // find the object in question and return a copy
    return *iterator;
}

If you need to modify the returned myObject, store your values as pointers and allocate them on the heap:

myObject* myFunction(const vector<myObject*>& objects)
{
    return *iterator;
}

That way you have control over when they're destructed.

Something like this will break your app:

g_vector<tmpClass> myVector;

    tmpClass t;
    t.i = 30;
    myVector.push_back(t);

    // my function returns a pointer to a value in myVector
    std::auto_ptr<tmpClass> t2(myFunction());

Problem is, you're trying to upcast to a richer object. You simply need to add the items to a new list:

if (myObject is IEnumerable)
{
   List<object> list = new List<object>();
   var enumerator = ((IEnumerable) myObject).GetEnumerator();
   while (enumerator.MoveNext())
   {
      list.Add(enumerator.Current);
   }
}

Yes, using System.Reflection:

using System.Reflection;

...

    string prop = "name";
    PropertyInfo pi = myObject.GetType().GetProperty(prop);
    pi.SetValue(myObject, "Bob", null);

Consider the following keyValueStore object :

var keyValueStore = (function() {
    var count = 0;
    var kvs = function() {
        count++;
        this.data = {};
        this.get = function(key) { return this.data[key]; };
        this.set = function(key, value) { this.data[key] = value; };
        this.delete = function(key) { delete this.data[key]; };
        this.getLength = function() {
            var l = 0;
            for (p in this.data) l++;
            return l;
        }
    };

    return  { // Singleton public properties
        'create' : function() { return new kvs(); },
        'count' : function() { return count; }
    };
})();

I can create a new instance of this object by doing this :

kvs = keyValueStore.create();

Each instance of this object would have the following public properties :

• data
• get
• set
• delete
• getLength

Now, suppose we create 100 instances of this keyValueStore object. Even though get, set, delete, getLength will do the exact same thing for each of these 100 instances, every instance has its own copy of this function.

Now, imagine if you could have just a single get, set, delete and getLength copy, and each instance would reference that same function. This would be better for performance and require less memory.

That's where prototypes come in. A prototype is a "blueprint" of properties that is inherited but not copied by instances. So this means that it exists only once in memory for all instances of an object and is shared by all of those instances.

Now, consider the keyValueStore object again. I could rewrite it like this :

var keyValueStore = (function() {
    var count = 0;
    var kvs = function() {
        count++;
        this.data = {};
    };

    kvs.prototype = {
        'get' : function(key) { return this.data[key]; },
        'set' : function(key, value) { this.data[key] = value; },
        'delete' : function(key) { delete this.data[key]; },
        'getLength' : function() {
            var l = 0;
            for (p in this.data) l++;
            return l;
        }
    };

    return  {
        'create' : function() { return new kvs(); },
        'count' : function() { return count; }
    };
})();

This does EXACTLY the same as the previous version of the keyValueStore object, except that all of its methods are now put in a prototype. What this means, is that all of the 100 instances now share these four methods instead of each having their own copy.

String interpolation to the rescue.

let imageUrl = 'imageurl.png';
$('myOjbect').css('background-image', `url(${imageUrl})`);

To prevent duplication in memory, resharper is suggesting this:

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myList as List<string>() ?? myEnumerable.ToList();

.ToList() returns a new immutable list. So changes to listAgain does not effect myList in @Tamas Czinege answer. This is correct in most instances for least two reasons: This helps prevent changes in one area effecting the other area (loose coupling), and it is very readable, since we shouldn't be designing code with compiler concerns.

But there are certain instances, like being in a tight loop or working on an embedded or low memory system, where compiler considerations should be taken into consideration.

Try the JavaScript in operator.

if ('key' in myObj)

And the inverse.

if (!('key' in myObj))

Be careful! The in operator matches all object keys, including those in the object's prototype chain.

Use myObj.hasOwnProperty('key') to check an object's own keys and will only return true if key is available on myObj directly:

myObj.hasOwnProperty('key')

Unless you have a specific reason to use the in operator, using myObj.hasOwnProperty('key') produces the result most code is looking for.

Just adding to this that in ES6 because of arrow functions you shouldn't need to do this because they capture the this value.

Objects in JavaScript can be thought of as maps between keys and values. The delete operator is used to remove these keys, more commonly known as object properties, one at a time.

var obj = {_x000D_
  myProperty: 1    _x000D_
}_x000D_
console.log(obj.hasOwnProperty('myProperty')) // true_x000D_
delete obj.myProperty_x000D_
console.log(obj.hasOwnProperty('myProperty')) // false

The delete operator does not directly free memory, and it differs from simply assigning the value of null or undefined to a property, in that the property itself is removed from the object. Note that if the value of a deleted property was a reference type (an object), and another part of your program still holds a reference to that object, then that object will, of course, not be garbage collected until all references to it have disappeared.

delete will only work on properties whose descriptor marks them as configurable.

Could do it with jQuery as follows:

var objectKeys = $.map(object, function(value, key) {
  return key;
});

To do this in any ES5-compatible environment, such as Node, Chrome, IE 9+, Firefox 4+, or Safari 5+:

Object.keys(obj).length

• Browser compatibility
• Object.keys documentation (includes a method you can add to non-ES5 browsers)

This will copy all readable and writable properties of an object to another.

 public class PropertyCopy<TSource, TTarget> 
                        where TSource: class, new()
                        where TTarget: class, new()
        {
            public static TTarget Copy(TSource src, TTarget trg, params string[] properties)
            {
                if (src==null) return trg;
                if (trg == null) trg = new TTarget();
                var fulllist = src.GetType().GetProperties().Where(c => c.CanWrite && c.CanRead).ToList();
                if (properties != null && properties.Count() > 0)
                    fulllist = fulllist.Where(c => properties.Contains(c.Name)).ToList();
                if (fulllist == null || fulllist.Count() == 0) return trg;

                fulllist.ForEach(c =>
                    {
                        c.SetValue(trg, c.GetValue(src));
                    });

                return trg;
            }
        }

and this is how you use it:

 var cloned = Utils.PropertyCopy<TKTicket, TKTicket>.Copy(_tmp, dbsave,
                                                            "Creation",
                                                            "Description",
                                                            "IdTicketStatus",
                                                            "IdUserCreated",
                                                            "IdUserInCharge",
                                                            "IdUserRequested",
                                                            "IsUniqueTicketGenerated",
                                                            "LastEdit",
                                                            "Subject",
                                                            "UniqeTicketRequestId",
                                                            "Visibility");

or to copy everything:

var cloned = Utils.PropertyCopy<TKTicket, TKTicket>.Copy(_tmp, dbsave);

Here's the most cross-browser solution.

This is better than the accepted answer because it uses native Object.keys if exists. Thus, it is the fastest for all modern browsers.

if (!Object.keys) {
    Object.keys = function (obj) {
        var arr = [],
            key;
        for (key in obj) {
            if (obj.hasOwnProperty(key)) {
                arr.push(key);
            }
        }
        return arr;
    };
}

Object.keys(obj).length;

An inner class cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?".

as u said here inner class cannot be static... i found the below code which is being given static....reason? or which is correct....

Yes, there is nothing in the semantics of a static nested type that would stop you from doing that. This snippet runs fine.

    public class MultipleInner {
        static class Inner {
        }   
    public static void main(String[] args) {
        for (int i = 0; i < 100; i++) {
            new Inner();
        }
    }
}

this is a code posted in this website...

for the question---> Can a Static Nested Class be Instantiated Multiple Times?

answer was--->

Now, of course the nested type can do its own instance control (e.g. private constructors, singleton pattern, etc) but that has nothing to do with the fact that it's a nested type. Also, if the nested type is a static enum, of course you can't instantiate it at all.

But in general, yes, a static nested type can be instantiated multiple times.

Note that technically, a static nested type is not an "inner" type.

With Markdown-2.5.2, you can use this:

[link](url){:target="_blank"}

Try this:

var body = document.getElementsByTagName('BODY')[0];
// CONDITION DOES NOT WORK
if ((body && body.readyState == 'loaded') || (body &&  body.readyState == 'complete') ) {
    DoStuffFunction();
} else {
    // CODE BELOW WORKS
    if (window.addEventListener) {
        window.addEventListener('load', DoStuffFunction, false);
    } else {
        window.attachEvent('onload',DoStuffFunction);
    }
}

In my opinion, some of the node.js examples are quite contrived.

You might expect to see something more like this in the real world

// square.js
function Square(width) {

  if (!(this instanceof Square)) {
    return new Square(width);
  }

  this.width = width;
};

Square.prototype.area = function area() {
  return Math.pow(this.width, 2);
};

module.exports = Square;

Usage

var Square = require("./square");

// you can use `new` keyword
var s = new Square(5);
s.area(); // 25

// or you can skip it!
var s2 = Square(10);
s2.area(); // 100

For the ES6 people

class Square {
  constructor(width) {
    this.width = width;
  }
  area() {
    return Math.pow(this.width, 2);
  }
}

export default Square;

Using it in ES6

import Square from "./square";
// ...

When using a class, you must use the new keyword to instatiate it. Everything else stays the same.

BEGIN;
INSERT INTO test_b (price_sum)
  SELECT price
  FROM   test_a;
INSERT INTO test_c (price_summ) 
  SELECT price
FROM   test_a;
COMMIT;

        <dd>Sub-Item 2.2</dd>
        <dd>Sub-Item 2.3</dd>
      <dt>List Item 3</dt>
        <dd>Sub-Item 3.1</dd>
    </dl>

You can use Map.

• A new data structure introduced in JavaScript ES6.
• Alternative to JavaScript Object for storing key/value pairs.
• Has useful methods for iteration over the key/value pairs.

var map = new Map();
map.set('name', 'John');
map.set('id', 11);

// Get the full content of the Map
console.log(map); // Map { 'name' => 'John', 'id' => 11 }

Get value of the Map using key

console.log(map.get('name')); // John 
console.log(map.get('id')); // 11

Get size of the Map

console.log(map.size); // 2

Check key exists in Map

console.log(map.has('name')); // true
console.log(map.has('age')); // false

Get keys

console.log(map.keys()); // MapIterator { 'name', 'id' }

Get values

console.log(map.values()); // MapIterator { 'John', 11 }

Get elements of the Map

for (let element of map) {
  console.log(element);
}

// Output:
// [ 'name', 'John' ]
// [ 'id', 11 ]

Print key value pairs

for (let [key, value] of map) {
  console.log(key + " - " + value);
}

// Output: 
// name - John
// id - 11

Print only keys of the Map

for (let key of map.keys()) {
  console.log(key);
}

// Output:
// name
// id

Print only values of the Map

for (let value of map.values()) {
  console.log(value);
}

// Output:
// John
// 11

if you are opening page on JavaScript popup then

 Response.Write("<script>javascript:window.close();</script>");

   if (i % 3 == 0)
   {

}

Q: Is this ok?
A: yes

Q: Is this expected?
Yes, this is expected (if you are using react-redux).

Q: Is this an anti-pattern?
A: No, this is not an anti-pattern.

It's called "connecting" your component or "making it smart". It's by design.

It allows you to decouple your component from your state an additional time which increases the modularity of your code. It also allows you to simplify your component state as a subset of your application state which, in fact, helps you comply with the Redux pattern.

Think about it this way: a store is supposed to contain the entire state of your application.
For large applications, this could contain dozens of properties nested many layers deep.
You don't want to haul all that around on each call (expensive).

Without mapStateToProps or some analog thereof, you would be tempted to carve up your state another way to improve performance/simplify.

Have a look at the example in this link :

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

matlab function:

function [lineAngle] = getLineAngle(x1, y1, x2, y2) 
    deltaY = y2 - y1;
    deltaX = x2 - x1;

    lineAngle = rad2deg(atan2(deltaY, deltaX));

    if deltaY < 0
        lineAngle = lineAngle + 360;
    end
end

See this answer for a a clean & simple 'class' solution with a private and public interface and support for composition

from the commandline:

chkdsk l: (wait for the scan to finish)

sizdir32 http://www.ltr-data.se/opencode.html/

var link = $(element);
var offset = link.offset();

var top = offset.top;
var left = offset.left;

var bottom = top + link.outerHeight();
var right = left + link.outerWidth();

(Assuming C, C++, Java, JavaScript)

| and & are bitwise operators while || and && are logical operators. Usually you'd want to use || and && for if statements and loops and such (i.e. for your examples above). The bitwise operators are for setting and checking bits within bitmasks.

You can add the image into a comment.

Right-click cell > Insert Comment > right-click on shaded (grey area) on outside of comment box > Format Comment > Colors and Lines > Fill > Color > Fill Effects > Picture > (Browse to picture) > Click OK

Microsoft Office 365 (2019) introduced new things called comments and renamed the old comments as "notes". Therefore in the steps above do New Note instead of Insert Comment. All other steps remain the same and the functionality still exists.

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

In about:config add content.cors.disable (empty string).

For impatient:

Same

Without passing argument, persist() and cache() are the same, with default settings:

• when RDD: MEMORY_ONLY
• when Dataset: MEMORY_AND_DISK

Difference:

Unlike cache(), persist() allows you to pass argument inside the bracket, in order to specify the level:

• persist(MEMORY_ONLY)
• persist(MEMORY_ONLY_SER)
• persist(MEMORY_AND_DISK)
• persist(MEMORY_AND_DISK_SER )
• persist(DISK_ONLY )

Voilà!

-O3 option turns on more expensive optimizations, such as function inlining, in addition to all the optimizations of the lower levels ‘-O2’ and ‘-O1’. The ‘-O3’ optimization level may increase the speed of the resulting executable, but can also increase its size. Under some circumstances where these optimizations are not favorable, this option might actually make a program slower.

SSH

If you are trying it with SSH, then the Host key Verification error can come due to several reasons.Follow these steps to overcome all the reasons.

1. Set the Environment variable as HOME and provide the address as the root directory of .ssh folder. e.g:- If your .ssh is kept inside Name folder. C:/Users/Name.
2. Now make sure that the public SSH key is being provided in the repository link also. Either it is github or bitbucket or any other.
3. Open git bash. And try cloning the project from the repository. This will help in adding your repository URL in the known_host file, which is being auto created in the .ssh folder.
4. Now open jenkins and create a new job. Then click on configure.
5. provide the cloning URL in Source code management under Git. The URL should be start with [email protected]/......... or ssh://proje........
6. Under the Credential you need to add the username and password of your repository form which you are cloning the project. Select that credential.
7. And now apply and save the configuration.
8. Bingo! Start building the project. I hope now you will not get any Host Key verification error!

I am used to having multiple .js files on my web site that depend one on another. To load them and ensure that the dependencies are evaluated in the right order, I have written a function that loads all the files and then, once they are all received, eval() them. The main drawback is that since this does not work with CDN. For such libraries (e.g., jQuery) it is better to include them statically. Note that inserting script nodes in the HTML dynamically won't guarantee that scripts are evaluated in the right order, at least not in Chrome (this was the major reason for writing this function).

function xhrs(reqs) {
  var requests = [] , count = [] , callback ;

  callback = function (r,c,i) {
    return function () {
      if  ( this.readyState == 4 ) {
        if (this.status != 200 ) {
          r[i]['resp']="" ;
        } 
        else {
          r[i]['resp']= this.responseText ;
        }
        c[0] = c[0] - 1 ;
        if ( c[0] == 0 ) {
          for ( var j = 0 ; j < r.length ; j++ ) {
            eval(r[j]['resp']) ;
          }
        }
      }
    }
  } ;
  if ( Object.prototype.toString.call( reqs ) === '[object Array]' ) {
    requests.length = reqs.length ;
  }
  else {
    requests.length = 1 ;
    reqs = [].concat(reqs);
  }
  count[0] = requests.length ;
  for ( var i = 0 ; i < requests.length ; i++ ) {
    requests[i] = {} ;
    requests[i]['xhr'] = new XMLHttpRequest () ;
    requests[i]['xhr'].open('GET', reqs[i]) ;
    requests[i]['xhr'].onreadystatechange = callback(requests,count,i) ;
    requests[i]['xhr'].send(null);
  }
}

I haven't figured out how to make references to the same value without creating an array (for count). Otherwise I think it is self-explanatory (when everything is loaded, eval() every file in the order given, otherwise just store the response).

Usage example:

xhrs( [
       root + '/global.js' ,
       window.location.href + 'config.js' ,
       root + '/js/lib/details.polyfill.min.js',
       root + '/js/scripts/address.js' ,
       root + '/js/scripts/tableofcontents.js' 
]) ;

The golden rule is to NOT under ANY circumstances lock your users browser. After that, I usually look at execution time, followed by memory usage (unless you're doing something crazy, in which case it could be a higher priority).

Sometimes you get broken code, when using dex2jar/apktool, most notably in loops. To avoid this, use jadx, which decompiles dalvik bytecode into java source code, without creating a .jar/.class file first as dex2jar does (apktool uses dex2jar I think). It is also open-source and in active development. It even has a GUI, for GUI-fanatics. Try it!

In case anyone wants it, you can also make the timer async and await it:

export const delay = (ms) => new Promise((res) => setTimeout(res, ms));

Usage:

// do something
await delay(500); // wait 0.5 seconds
// do something else

If the worksheet you want to retrieve exists at compile-time in ThisWorkbook (i.e. the workbook that contains the VBA code you're looking at), then the simplest and most consistently reliable way to refer to that Worksheet object is to use its code name:

Debug.Print Sheet1.Range("A1").Value

You can set the code name to anything you need (as long as it's a valid VBA identifier), independently of its "tab name" (which the user can modify at any time), by changing the (Name) property in the Properties toolwindow (F4):

The Name property refers to the "tab name" that the user can change on a whim; the (Name) property refers to the code name of the worksheet, and the user can't change it without accessing the Visual Basic Editor.

VBA uses this code name to automatically declare a global-scope Worksheet object variable that your code gets to use anywhere to refer to that sheet, for free.

In other words, if the sheet exists in ThisWorkbook at compile-time, there's never a need to declare a variable for it - the variable is already there!

If the worksheet is created at run-time (inside ThisWorkbook or not), then you need to declare & assign a Worksheet variable for it.

Use the Worksheets property of a Workbook object to retrieve it:

Dim wb As Workbook
Set wb = Application.Workbooks.Open(path)

Dim ws As Worksheet
Set ws = wb.Worksheets(nameOrIndex)

Important notes...

• Both the name and index of a worksheet can easily be modified by the user (accidentally or not), unless workbook structure is protected. If workbook isn't protected, you simply cannot assume that the name or index alone will give you the specific worksheet you're after - it's always a good idea to validate the format of the sheet (e.g. verify that cell A1 contains some specific text, or that there's a table with a specific name, that contains some specific column headings).

• Using the Sheets collection contains Worksheet objects, but can also contain Chart instances, and a half-dozen more legacy sheet types that are not worksheets. Assigning a Worksheet reference from whatever Sheets(nameOrIndex) returns, risks throwing a type mismatch run-time error for that reason.

• Not qualifying the Worksheets collection is an implicit ActiveWorkbook reference - meaning the Worksheets collection is pulling from whatever workbook is active at the moment the instruction is executing. Such implicit references make the code frail and bug-prone, especially if the user can navigate and interact with the Excel UI while code is running.

• Unless you mean to activate a specific sheet, you never need to call ws.Activate in order to do 99% of what you want to do with a worksheet. Just use your ws variable instead.

It's just a matter of personal preference. There is no difference between these two ways, other than a few bytes saved with the second form if you strip out the white space.

You can use a structure like the following:

 while ((line = bufferedReader.readLine()) != null) {
            System.out.println(line);
        }

This was OK for me:

this.conn = (Connection)DriverManager
    .getConnection(url + dbName + "?useSSL=false", userName, password);

Before you begin: You must know that every object in memory needs to be deallocated from memory for a new writer to happen. You can't just simply write on top of something as you do on paper. You must first erase (dealloc) it and then you can write onto it. If at the moment that the erase is done (or half done) and nothing has yet been wrote (or half wrote) and you try to read it could be very problematic! Atomic and nonatomic help you treat this problem in different ways.

First read this question and then read Bbum's answer. In addition, then read my summary.

atomic will ALWAYS guarantee

• If two different people want to read and write at the same time, your paper won't just burn! --> Your application will never crash, even in a race condition.
• If one person is trying to write and has only written 4 of the 8 letters to write, then no can read in the middle, the reading can only be done when all 8 letters is written --> No read(get) will happen on 'a thread that is still writing', i.e. if there are 8 bytes to bytes to be written, and only 4 bytes are written——up to that moment, you are not allowed to read from it. But since I said it won't crash then it would read from the value of an autoreleased object.
• If before writing you have erased that which was previously written on paper and then someone wants to read you can still read. How? You will be reading from something similar to Mac OS Trash bin ( as Trash bin is not still 100% erased...it's in a limbo) ---> If ThreadA is to read while ThreadB has already deallocated to write, you would get a value from either the final fully written value by ThreadB or get something from autorelease pool.

Retain counts are the way in which memory is managed in Objective-C. When you create an object, it has a retain count of 1. When you send an object a retain message, its retain count is incremented by 1. When you send an object a release message, its retain count is decremented by 1. When you send an object an autorelease message, its retain count is decremented by 1 at some stage in the future. If an object's retain count is reduced to 0, it is deallocated.

• Atomic doesn't guarantee thread safety, though it's useful for achieving thread safety. Thread Safety is relative to how you write your code/ which thread queue you are reading/writing from. It only guarantees non-crashable multithreading.

What?! Are multithreading and thread safety different?

Yes. Multithreading means: multiple threads can read a shared piece of data at the same time and we will not crash, yet it doesn't guarantee that you aren't reading from a non-autoreleased value. With thread safety, it's guaranteed that what you read is not auto-released. The reason that we don't make everything atomic by default is, that there is a performance cost and for most things don't really need thread safety. A few parts of our code need it and for those few parts, we need to write our code in a thread-safe way using locks, mutex or synchronization.

nonatomic

• Since there is no such thing like Mac OS Trash Bin, then nobody cares whether or not you always get a value (<-- This could potentially lead to a crash), nor anybody cares if someone tries to read halfway through your writing (although halfway writing in memory is very different from halfway writing on paper, on memory it could give you a crazy stupid value from before, while on paper you only see half of what's been written) --> Doesn't guarantee to not crash, because it doesn't use autorelease mechanism.
• Doesn't guarantee full written values to be read!
• Is faster than atomic

Overall they are different in 2 aspects:

• Crashing or not because of having or not having an autorelease pool.

• Allowing to be read right in the middle of a 'not yet finished write or empty value' or not allowing and only allowing to read when the value is fully written.

The error is clear, isn't it?

You've not added the path where sqljdbc_auth.dll is present. Find out in the system where the DLL is and add that to your classpath.

And if that also doesn't work, add the folder where the DLL is present (I'm assuming \Microsoft SQL Server JDBC Driver 3.0\sqljdbc_3.0\enu\auth\x86) to your PATH variable.

Again if you're going via ant or cmd you have to explicitly mention the path using -Djava.library.path=[path to MS_SQL_AUTH_DLL]

less typing way:

func fprint(format: String, _ args: CVarArgType...) {
    print(NSString(format: format, arguments: getVaList(args)))
}

Yes, you can connect the raspberry direct to your PC without router. For this is necessary that the raspberry and your computer are on the same subnet, and they both have a static ip configured (And an Ethernet cable connected between the two devices).

An ideal configuration would be the following:

Raspberry on eth0: IP: 192.168.1.10 SubNet: 255.255.255.0

Your PC: IP: 192.168.1.11 SubNet 255.255.255.0

To set a manual IP on raspberry you can follow this guide

In your PC you can set a manual IP in the network adapter settings,and the procedure depends on your operating system.

When you have configured the two static IP, you can connect to the raspberry via SSH using the IP set (192.168.1.10).

Another simpler method is to attach on GPIO a button to turn off the raspberry! Take a look here!

As everybody else has said, there is no difference. (As a sanity check I did some tests, but it was a waste of time, of course they work the same.)

But there are actually FOUR types of inequality operators: !=, ^=, <>, and ¬=. See this page in the Oracle SQL reference. On the website the fourth operator shows up as ÿ= but in the PDF it shows as ¬=. According to the documentation some of them are unavailable on some platforms. Which really means that ¬= almost never works.

Just out of curiosity, I'd really like to know what environment ¬= works on.

Refer to the ASP.NET page lifecycle to help find the right event to override. It really depends what you want to do. But yes, there is an unload event.

    protected override void OnUnload(EventArgs e)
    {
        base.OnUnload(e);

        // your code
    }

But just remember (from the above link): During the unload stage, the page and its controls have been rendered, so you cannot make further changes to the response stream. If you attempt to call a method such as the Response.Write method, the page will throw an exception.

If it's not a literal, you have to use \\\\ so that you get \\ which means an escaped backslash.

That's because there are two representations. In the string representation of your regex, you have "\\\\", Which is what gets sent to the parser. The parser will see \\ which it interprets as a valid escaped-backslash (which matches a single backslash).

As Fermin said, a variable in the global scope should be accessible to all scripts loaded after it is declared. You could also use a property of window or (in the global scope) this to get the same effect.

// first.js
var colorCodes = {

  back  : "#fff",
  front : "#888",
  side  : "#369"

};

... in another file ...

// second.js
alert (colorCodes.back); // alerts `#fff`

... in your html file ...

<script type="text/javascript" src="first.js"></script> 
<script type="text/javascript" src="second.js"></script> 

find is also printing the directory itself:

$ find .vim/ -maxdepth 1 -type d
.vim/
.vim/indent
.vim/colors
.vim/doc
.vim/after
.vim/autoload
.vim/compiler
.vim/plugin
.vim/syntax
.vim/ftplugin
.vim/bundle
.vim/ftdetect

You can instead test the directory's children and do not descend into them at all:

$ find .vim/* -maxdepth 0 -type d
.vim/after
.vim/autoload
.vim/bundle
.vim/colors
.vim/compiler
.vim/doc
.vim/ftdetect
.vim/ftplugin
.vim/indent
.vim/plugin
.vim/syntax

$ find .vim/* -maxdepth 0 -type d | wc -l
11
$ find .vim/ -maxdepth 1 -type d | wc -l
12

You can also use ls:

$ ls -l .vim | grep -c ^d
11


$ ls -l .vim

Python lists have the index() method, which you can use to find the position of the first occurrence of an item in a list. Note that list.index() raises ValueError when the item is not present in the list, so you may need to wrap it in try/except:

try:
    idx = lst.index(value)
except ValueError:
    idx = None

To find the position of the last occurrence of an item in a list efficiently (i.e. without creating a reversed intermediate list) you can use this function:

def rindex(lst, value):
    for i, v in enumerate(reversed(lst)):
        if v == value:
            return len(lst) - i - 1  # return the index in the original list
    return None    

print(rindex([1, 2, 3], 3))     # 2
print(rindex([3, 2, 1, 3], 3))  # 3
print(rindex([3, 2, 1, 3], 4))  # None

Create a file called config inside ~/.ssh. Inside the file you can add:

Host *
    User buck

Or add

Host example
    HostName example.net
    User buck

The second example will set a username and is hostname specific, while the first example sets a username only. And when you use the second one you don't need to use ssh example.net; ssh example will be enough.

Assuming you're running on a Windows machine...

1. Hit the F12 key
2. Select the Scripts, or Sources, tab in the developer tools
3. Click the little folder icon in the top level
4. Select your JavaScript file
5. Add a breakpoint by clicking on the line number on the left (adds a little blue marker)
6. Execute your JavaScript

Then during execution debugging you can do a handful of stepping motions...

• F8 Continue: Will continue until the next breakpoint
• F10 Step over: Steps over next function call (won't enter the library)
• F11 Step into: Steps into the next function call (will enter the library)
• Shift + F11 Step out: Steps out of the current function

Update

After reading your updated post; to debug your code I would recommend temporarily using the jQuery Development Source Code. Although this doesn't directly solve your problem, it will allow you to debug more easily. For what you're trying to achieve I believe you'll need to step-in to the library, so hopefully the production code should help you decipher what's happening.

Bootstrap 2.3.x and later supports the dropdown-submenu..

<ul class="dropdown-menu">

            <li class="dropdown-submenu">
                <a tabindex="-1" href="#">More options</a>
                <ul class="dropdown-menu">

Working demo on Bootply.com

Use index=False.

df.to_csv('your.csv', index=False)

I had the same issue, but I just wrapped the arguments like this and it works now.

    $args = array();
    $args['Header'] = array(
        'CustomerCode' => 'dsadsad',
        'Language' => 'fdsfasdf'
    );
    $args['RequestObject'] = $whatever;

    // this was the catch, double array with "Request"
    $response = $this->client->__soapCall($name, array(array( 'Request' => $args )));

Using this function:

 print_r($this->client->__getLastRequest());

You can see the Request XML whether it's changing or not depending on your arguments.

Use [ trace = 1, exceptions = 0 ] in SoapClient options.

Try this. Works on both windows or linux server..

Try this..

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

It seems the doc evolved.

One should now use : $("#datetimepicker1").data("DateTimePicker").date().

NB : Doing so return a Moment object, not a Date object

import numpy as np
import pandas as pd
import scipy.sparse as sparse

df = pd.DataFrame(np.arange(1,10).reshape(3,3))
arr = sparse.coo_matrix(([1,1,1], ([0,1,2], [1,2,0])), shape=(3,3))
df['newcol'] = arr.toarray().tolist()
print(df)

yields

   0  1  2     newcol
0  1  2  3  [0, 1, 0]
1  4  5  6  [0, 0, 1]
2  7  8  9  [1, 0, 0]

" is valid in both HTML5 and HTML4.

' is valid in HTML5, but not HTML4. However, most browsers support ' for HTML4 anyway.

You no longer need {this.props.children}. Now you can wrap your child component using render in Route and pass your props as usual:

<BrowserRouter>
  <div>
    <ul>
      <li><Link to="/">Home</Link></li>
      <li><Link to="/posts">Posts</Link></li>
      <li><Link to="/about">About</Link></li>
    </ul>

    <hr/>

    <Route path="/" exact component={Home} />
    <Route path="/posts" render={() => (
      <Posts
        value1={1}
        value2={2}
        data={this.state.data}
      />
    )} />
    <Route path="/about" component={About} />
  </div>
</BrowserRouter>

If you want to have a behavior similar to JMP, creating column titles that keep all info from the multi index you can use:

newidx = []
for (n1,n2) in df.columns.ravel():
    newidx.append("%s-%s" % (n1,n2))
df.columns=newidx

It will change your dataframe from:

    I                       V
    mean        std         first
V
4200.0  25.499536   31.557133   4200.0

4500.0  26.786458   32.811633   4500.0

to

    I-mean      I-std       V-first
V
4200.0  25.499536   31.557133   4200.0

4500.0  26.786458   32.811633   4500.0

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

Regarding to all your answers, I have created a solution that works perfectly for me.

If you are running in Windows you can use the following command.

Drive:

cd "Script location"
schtasks /run /tn "TASK1"
schtasks /run /tn "TASK2"
schtasks /run /tn "TASK3"
exit

var element = $("#parentDiv .myClassNameOfInterest")

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()

Have you tried using @JsonProperty?

@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}

I have a simpler and elegant solution that doesn't mess up with classes, styles, opacities and stuff.

For the draggable element - you add 'start' event which will execute every time you try to move the element somewhere. You will have a condition which move is not legal. For the moves that are illegal - prevent them with 'e.preventDefault();' like in the code below.

    $(".disc").draggable({
        revert: "invalid", 
        cursor: "move",
        start: function(e, ui){                
            console.log("element is moving");

            if(SOME_CONDITION_FOR_ILLEGAL_MOVE){
                console.log("illegal move");
                //This will prevent moving the element from it's position
                e.preventDefault();
            }    

        }
    });

You are welcome :)

For sake of completeness, as of PHP 5.1 this works, too:

<?php
function title($title, $name) {
    return sprintf("%s. %s\r\n", $title, $name);
}
$function = new ReflectionFunction('title');
$myArray = array('Dr', 'Phil');
echo $function->invokeArgs($myArray);  // prints "Dr. Phil"
?>

See: http://php.net/reflectionfunction.invokeargs

For methods you use ReflectionMethod::invokeArgs instead and pass the object as first parameter.

When you are working with a Gitlab or Github you can run in trouble in this way. You squash your commits with one of the above method. My preferite one is:

git rebase -i HEAD~4
or
git rebase -i origin/master

select squash or fixup for yours commit. At this point you would check with git status. And the message could be:

    On branch ABC-1916-remote
    Your branch and 'origin/ABC-1916' have diverged,
    and have 1 and 7 different commits each, respectively.
      (use "git pull" to merge the remote branch into yours)

And you can be tempted to pull it. DO NOT DO THAT or you will be in the same situation as before.

Instead push to your origin with:

git push origin +ABC-1916-remote:ABC-1916

The + allow to force push only to one branch.

For Hp-UX only below command worked for me:

TZ=aaa24 date +%Y%m%d

you can use it as :

ydate=`TZ=aaa24 date +%Y%m%d`

echo $ydate

You can use bc (calculator). Assuming your file with #s is called "n":

$ cat n
1
2
3
$ (cat n | tr "\012" "+" ; echo "0") | bc 
6

The tr changes all newlines to "+"; then we append 0 after the last plus, then we pipe the expression (1+2+3+0) to the calculator

Or, if you are OK with using awk or perl, here's a Perl one-liner:

$perl -nle '$sum += $_ } END { print $sum' n
6

I think using !important is not a very wise option. It may cause for many other issues specially when making the site responsive. So, my understanding is that, the best way to do this to use custom button CSS class with .btn bootstrap class. .btn is the base style class for bootstrap button. So, keep that as the layout, we can change other styles using our custom css class. One more extra thing I want to mention here. Some people are trying to remove blue outline from the buttons. It's not a good idea because that accessibility issue when using keyboard. Change it's color using outline-color: instead.

I think a correct approach would be by means of Regex:

String fileContent = <text from file>;    
String[] words = Pattern.compile("\\s+").split(fileContent);
System.out.println("File has " + words.length + " words");

Hope it helps. The "\s+" meaning is in Pattern javadoc

Suggest the correct permission, if for Apache,

sudo chown -R apache:apache apppath/app/storage

I am going to use this one. Very similar to third one shown by @Marin.

Similar to most-liked answer, but works slightly faster:

WITH upsert AS (UPDATE spider_count SET tally=1 WHERE date='today' RETURNING *)
INSERT INTO spider_count (spider, tally) SELECT 'Googlebot', 1 WHERE NOT EXISTS (SELECT * FROM upsert)

You could set your _JAVA_OPTIONS environmental variable. For example in bash this would do the trick:

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

I put that into my bash login script and it seems to do the trick.

Many ways to skin this cat. I put a simple function in each table's package...

function exists( id_in in yourTable.id%type ) return boolean is
  res boolean := false;
begin
  for c1 in ( select 1 from yourTable where id = id_in and rownum = 1 ) loop
    res := true;
    exit; -- only care about one record, so exit.
  end loop;
  return( res );
end exists;

Makes your checks really clean...

IF pkg.exists(someId) THEN
...
ELSE
...
END IF;

You need to turn on dbms_output. In Oracle SQL Developer:

1. Show the DBMS Output window (View->DBMS Output).
2. Press the "+" button at the top of the Dbms Output window and then select an open database connection in the dialog that opens.

In SQL*Plus:

 SET SERVEROUTPUT ON

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

Use the pull request builder plugin: https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin

It's really straightforward. You can then setup GitHub webhooks to trigger builds.

Try adding the other two non COUNT columns to the GROUP BY:

select CURRENT_DATE-1 AS day, 
model.name, 
attempt.type, 
CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END, 
count(*) 
from attempt attempt, prod_hw_id prod_hw_id, model model
where time >= '2013-11-06 00:00:00'  
AND time < '2013-11-07 00:00:00'
AND attempt.hard_id = prod_hw_id.hard_id
AND prod_hw_id.model_id = model.model_id
group by 1,2,3,4
order by model.name, attempt.type, attempt.result;

Just add your text between the font tags:

for blue color

<string name="hello_world"><font color='blue'>Hello world!</font></string>

or for red color

<string name="hello_world"><font color='red'>Hello world!</font></string>

The Pair class from Commons Lang might help:

Pair<String, String> keyValue = new ImmutablePair("key", "value");

Of course, you would need to include commons-lang.

Both tools are meant to work with text and there are tasks both tools can be used for.

For me the rule to separate them is: Use sed to automate tasks you would do otherwise in a text editor manually. That's why it is called stream editor. (You can use the same commands to edit text in vim). Use awk if you want to analyze text, meaning counting fields, calculate totals, extract and reorganize structures etc.

Also you should not forget about grep. Use grep if you only want to search/extract something in a text (file)

Without you providing any specific error message, it's hard to give specific suggestions.

However, I was using the same example and was getting a permissions exception on File.OpenWrite - using the localFileName variable, because using Path.GetFile was pointing to a location that obviously would not have permissions for opening a file > C:\ProgramFiles\IIS(Express)\filename.doc

I found that using System.IO.Path.GetFileName is not correct, use System.IO.Path.GetFullPath instead, point to your file starting with "C:\..."

Also open your solution in FileExplorer and grant permissions to asp.net for the file or any folders holding the file. I was able to download my file at that point.

You can get port info via

@Value("${local.server.port}")
private String serverPort;

A few comments:

1. Since the search position is important you should specify where you start the search. I use ws.[a1] and xlNext below so my search starts in A2 of the specified sheet.
2. Some of Finds arguments - including lookat use the prior search settings. So you should always specify xlWhole or xlPart to match all or part a string respectively.
3. You can do all you want - including inserting a row, and prompting the user for a new value (my code will suggest 20 if the prior value was 19) without using Select or Activate

suggested code

Sub FindEm()
Dim Wb As Workbook
Dim ws As Worksheet
Dim rng1 As Range
Set Wb = ThisWorkbook
Set ws = Wb.Sheets("ECM Overview")
Set rng1 = ws.Range("A:A").Find("ProjTemp", ws.[a1], xlValues, xlWhole, , xlNext)
If Not rng1 Is Nothing Then
rng1.EntireRow.Insert
rng1.Offset(-1, 0).Value = Application.InputBox("Please enter data", "User Data Entry", rng1.Offset(-2, 0) + 1, , , , , 1)
Else
MsgBox "ProjTemp not found", vbCritical
End If
End Sub

It can be done via https and oauth or ssh.

https and oauth: create an access token that has "repo" scope and then use this syntax:

"package-name": "git+https://<github_token>:[email protected]/<user>/<repo>.git"

or

ssh: setup ssh and then use this syntax:

"package-name": "git+ssh://[email protected]:<user>/<repo>.git"

(note the use of colon instead of slash before user)

I found another solution to get the data. according to the documentation Please check documentation link

In service file add following.

import { Injectable } from '@angular/core';
import { AngularFireDatabase } from 'angularfire2/database';

@Injectable()
export class MoviesService {

  constructor(private db: AngularFireDatabase) {}
  getMovies() {
    this.db.list('/movies').valueChanges();
  }
}

In Component add following.

import { Component, OnInit } from '@angular/core';
import { MoviesService } from './movies.service';

@Component({
  selector: 'app-movies',
  templateUrl: './movies.component.html',
  styleUrls: ['./movies.component.css']
})
export class MoviesComponent implements OnInit {
  movies$;

  constructor(private moviesDb: MoviesService) { 
   this.movies$ = moviesDb.getMovies();
 }

In your html file add following.

<li  *ngFor="let m of movies$ | async">{{ m.name }} </li>

Disclosure: I wrote FieldVal.

Here is a solution using FieldVal. By using FieldVal UI to build a form and then FieldVal to validate the input, you can pass the error straight back into the form.

You can even run the validation code on the backend (if you're using Node.js) and show the error in the form without wiring all of the fields up manually.

Live demo: http://codepen.io/MarcusLongmuir/pen/WbOydx

function validate_form(data) {
    // This would work on the back end too (if you're using Node)

    // Validate the provided data
    var validator = new FieldVal(data);
    validator.get("email", BasicVal.email(true));
    validator.get("title", BasicVal.string(true));
    validator.get("url", BasicVal.url(true));
    return validator.end();
}


$(document).ready(function(){

    // Create a form and add some fields
    var form = new FVForm()
    .add_field("email", new FVTextField("Email"))
    .add_field("title", new FVTextField("Title"))
    .add_field("url", new FVTextField("URL"))
    .on_submit(function(value){

        // Clear the existing errors
        form.clear_errors();

        // Use the function above to validate the input
        var error = validate_form(value);

        if (error) {
            // Pass the error into the form
            form.error(error);
        } else {
            // Use the data here
            alert(JSON.stringify(value));
        }
    })

    form.element.append(
        $("<button/>").text("Submit")
    ).appendTo("body");

    //Pre-populate the form
    form.val({
        "email": "[email protected]",
        "title": "Your Title",
        "url": "http://www.example.com"
    })
});

If you don't have a mac, on windows you can open Paint and save as PNG with correct dimensions 1024x1024

I believe that echo outputs a trailing newline. Try using -n as a parameter to echo to skip the newline.

Hey I just had this problem and found that I wasn't looking at the folder location closely enough:

I had

require_once /vagrant/public/liberate/**APP**/vendor/autoload.php

What worked was:

require_once /vagrant/public/liberate/vendor/autoload.php

It was very easy (as a beginner) to overlook this very unnoticeable issue. Yes I do realize that the require issue being logged points directly to the issue at hand, but if you are a beginner, like me, these things can be easily overlooked.

FIX:

Have a good look at the debug of ( __ Dir __ '/etc/etc/etc/file.php') then have your file system open in a different window, and map the two directly. If there is even the slightest difference this require will not work and the above error will be spat out.

If You have got this error while running composer install command, don't worry. Steps to be followed and requirements:

• Step1: Go to server folder such as xampp(or) wampp etc.
  
• Step2: open php folder inside that and go to ext folder.
  
• Step3: If you find a file named as php_intl.dll no problem.

Just go to php.ini file and uncomment the line

From:

;extension=php_intl.dll

To:

extension=php_intl.dll

• Step4: restart xampp, thats it

Note: If you don't find any of the file named as php_intl.dll, then you need to upgrade the PHP version.

i assume you are working with nullable datatypes, you can do something like this:

var t = things.Where(x => x!=null && x.Value.ID == long.Parse(options.ID)).FirstOrDefault();
var res = t == null ? "" : t.Value;

I like Gromer's answer, but it leaves me with a question: What if I have multiple 'btnAwesome's in different controls?

To cater for that possibility, I would do the following:

$(document).ready(function() {
  $('#<%=myButton.ClientID %>').click(function() {
    // Do client side button click stuff here.
  });
});

It's not a regex match, but in my opinion, a regex match isn't what's needed here. If you're referencing a particular button, you want a precise text match such as this.

If, however, you want to do the same action for every btnAwesome, then go with Gromer's answer.

print array.sum / array.count is how i've done it

Just import AVFoundation and use AVMakeRectWithAspectRatioInsideRect(CGRectCurrentSize, CGRectMake(0, 0, YOUR_WIDTH, CGFLOAT_MAX)

copy tablename from 'filepath\filename' DELIMITERS '=' ENCODING 'WIN1252';

you can try this to handle UTF8 encoding.

You can apply any one approach:

$("#Input_Id").change(function(){   // 1st
    // do your code here
    // When your element is already rendered
});


$("#Input_Id").on('change', function(){    // 2nd (A)
    // do your code here
    // It will specifically called on change of your element
});

$("body").on('change', '#Input_Id', function(){    // 2nd (B)
    // do your code here
    // It will filter the element "Input_Id" from the "body" and apply "onChange effect" on it
});

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

If you want to unstage all the changes use below command,

git reset --soft HEAD

In the case you want to unstage changes and revert them from the working directory,

git reset --hard HEAD

Add Content-length header describing size of zip file in bytes.

header("Content-type: application/zip"); 
header("Content-Disposition: attachment; filename=$archive_file_name");
header("Content-length: " . filesize($archive_file_name));
header("Pragma: no-cache"); 
header("Expires: 0"); 
readfile("$archive_file_name");

Also make sure that there is absolutely no white space before <? and after ?>. I see a space here:

?

 <?php
$file_names = array('iMUST Operating Manual V1.3a.pdf','iMUST Product Information Sheet.pdf');

To create a test case template:

"New" -> "JUnit Test Case" -> Select "Class under test" -> Select "Available methods". I think the wizard is quite easy for you.

As Tasnim Fabiha mentioned, it is possible to change font for TextBox in order to show only dots/asterisks. But I wasn't able to find his font...so I give you my working example:

<TextBox Text="{Binding Password}" 
     FontFamily="pack://application:,,,/Resources/#password" />

Just copy-paste won't work. Firstly you have to download mentioned font "password.ttf" link: https://github.com/davidagraf/passwd/blob/master/public/ttf/password.ttf Then copy that to your project Resources folder (Project->Properties->Resources->Add resource->Add existing file). Then set it's Build Action to: Resource.

After this you will see just dots, but you can still copy text from that, so it is needed to disable CTRL+C shortcut like this:

<TextBox Text="{Binding Password}" 
     FontFamily="pack://application:,,,/Resources/#password" > 
    <TextBox.InputBindings>
        <!--Disable CTRL+C -->
        <KeyBinding Command="ApplicationCommands.NotACommand"
            Key="C"
            Modifiers="Control" />
    </TextBox.InputBindings>
</TextBox>

The Reverse Proxy method

• Method type: Ajax

Setting up a simple reverse proxy on the server, will allow the browser to use relative paths for the Ajax requests, while the server would be acting as a proxy to any remote location.

If using mod_proxy in Apache, the fundamental configuration directive to set up a reverse proxy is the ProxyPass. It is typically used as follows:

ProxyPass     /ajax/     http://other-domain.com/ajax/

In this case, the browser would be able to request /ajax/web_service.xml as a relative URL, but the server would serve this by acting as a proxy to http://other-domain.com/ajax/web_service.xml.

One interesting feature of the this method is that the reverse proxy can easily distribute requests towards multiple back-ends, thus acting as a load balancer.

Type this:

mysql --help 

Then look at the output. There is a block of text about 3/4 the way down describing what files it finds its defaults .my.cnf from. Here is an example from XAMPP v3.2.1:

Default options are read from the following files in the given order:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf

Your setup may differ. You will have to run the command to check the actual paths on your particular system.

This is not possible in modern browsers, and for good reason. Modern browsers offer password managers, which enable users to use stronger passwords than they would usually.

As explained by MDN: How to Turn Off Form Autocompletion:

Modern browsers implement integrated password management: when the user enters a username and password for a site, the browser offers to remember it for the user. When the user visits the site again, the browser autofills the login fields with the stored values.

Additionally, the browser enables the user to choose a master password that the browser will use to encrypt stored login details.

Even without a master password, in-browser password management is generally seen as a net gain for security. Since users do not have to remember passwords that the browser stores for them, they are able to choose stronger passwords than they would otherwise.

For this reason, many modern browsers do not support autocomplete="off" for login fields:

• If a site sets autocomplete="off" for a form, and the form includes username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page.

• If a site sets autocomplete="off" for username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page.

This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).

If an author would like to prevent the autofilling of password fields in user management pages where a user can specify a new password for someone other than themself, autocomplete="new-password" should be specified, though support for this has not been implemented in all browsers yet.

Before, this could be downloaded with streamlink but YouTube changed HLS rewinding with DASH. Therefore the way to do it below (that Prashant Adlinge commented) no longer works for YouTube:

In case you need both max and min from same table:

    select * from (
(select city, length(city) as maxlen from station
order by maxlen desc limit 1)
union
(select city, length(city) as minlen from station
order by minlen,city limit 1))a;

The following snippet will return the public ip of the remote machine and also default ip(i.e: LAN)

This will print ip's in quotes also to avoid confusion in using config files.

In my case, it was because of exception inside the constructor of my injected dependency (in your example - inside DashboardRepository constructor). The exception was caught somewhere inside MVC infrastructure. I found this after I added logs in relevant places.

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

and, for completeness and with regards to this question asking about changing string columns only, there's mutate_if:

data <- cbind(stringVar = sample(c("foo","bar"),10,replace=TRUE),
              data.frame(matrix(sample(1:40), 10, 10, dimnames = list(1:10, LETTERS[1:10]))),stringsAsFactors=FALSE)     

factoredData = data %>% mutate_if(is.character,funs(factor(.)))

What I believe user2087510 meant was:

name = 'something'
name = name.replace("'", "\\'")

I have also used this with success.

Here's a link which provides two other solutions without using any visited flags.

https://leetcode.com/problems/binary-tree-postorder-traversal/

This is obviously a stack-based solution due to the lack of parent pointer in the tree. (We wouldn't need a stack if there's parent pointer).

We would push the root node to the stack first. While the stack is not empty, we keep pushing the left child of the node from top of stack. If the left child does not exist, we push its right child. If it's a leaf node, we process the node and pop it off the stack.

We also use a variable to keep track of a previously-traversed node. The purpose is to determine if the traversal is descending/ascending the tree, and we can also know if it ascend from the left/right.

If we ascend the tree from the left, we wouldn't want to push its left child again to the stack and should continue ascend down the tree if its right child exists. If we ascend the tree from the right, we should process it and pop it off the stack.

We would process the node and pop it off the stack in these 3 cases:

1. The node is a leaf node (no children)
2. We just traverse up the tree from the left and no right child exist.
3. We just traverse up the tree from the right.

I have found that urllib has some really good code to pick up the system's proxy settings and they happen to be in the correct form to use directly. You can use this like:

import urllib

...
r = requests.get('http://example.org', proxies=urllib.request.getproxies())

It works really well and urllib knows about getting Mac OS X and Windows settings as well.

To use quotes just for completeness.

Try changing your headers to this:

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1" . "\r\n";
$headers .= "From: [email protected]" . "\r\n" .
"Reply-To: [email protected]" . "\r\n" .
"X-Mailer: PHP/" . phpversion();

For a few reasons.

• One of which is the need of a Reply-To and,

• The use of apostrophes instead of double-quotes. Those two things in my experience with forms, is usually what triggers a message ending up in the Spam box.

You could also try changing the $from to:

$from = "[email protected]";

EDIT:

See these links I found on the subject https://stackoverflow.com/a/9988544/1415724 and https://stackoverflow.com/a/16717647/1415724 and https://stackoverflow.com/a/9899837/1415724

Just change the mime type to: type="audio/mpeg", this way chrome will honor the autostart="false" parameter.

What about

scope = _.extend(scope, ParentScope);

Where ParentScope is an injected service?

My solution:

let isEmpty = (val) => {
    let typeOfVal = typeof val;
    switch(typeOfVal){
        case 'object':
            return (val.length == 0) || !Object.keys(val).length;
            break;
        case 'string':
            let str = val.trim();
            return str == '' || str == undefined;
            break;
        case 'number':
            return val == '';
            break;
        default:
            return val == '' || val == undefined;
    }
};
console.log(isEmpty([1,2,4,5])); // false
console.log(isEmpty({id: 1, name: "Trung",age: 29})); // false
console.log(isEmpty('TrunvNV')); // false
console.log(isEmpty(8)); // false
console.log(isEmpty('')); // true
console.log(isEmpty('   ')); // true
console.log(isEmpty([])); // true
console.log(isEmpty({})); // true

StringUtils.substringAfterLast("abcd: efg: 1006746", ": ") = "1006746";

As long as the format of the string is fixed you can use substringAfterLast.

I guess the issues happens at the encode strings. I solved same issues. Please try adding trim() at last of the encode string.

I know, I am late to this party, however I think it could be helpful for others.

Already posted answers are for csv and other one is by Interop dll where you need to install excel over the server, every approach has its own pros and cons. Here is an option which will give you

1. Perfect excel output [not csv]
2. With perfect excel and your data type match
3. Without excel installation
4. Pass list and get Excel output :)

you can achieve this by using NPOI DLL, available for both .net as well as for .net core

Steps :

1. Import NPOI DLL
2. Add Section 1 and 2 code provided below
3. Good to go

Section 1

This code performs below task :

1. Creating New Excel object - _workbook = new XSSFWorkbook();
2. Creating New Excel Sheet object - _sheet =_workbook.CreateSheet(_sheetName);
3. Invokes WriteData() - explained later Finally, creating and
4. returning MemoryStream object

Now you just need to call WriteData() function by passing your list, and it will provide you your excel.

I have tested it in WEB API and WEB API Core, works like a charm.

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

$("#selectsearch").change(function() {
  var action = $(this).val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + action);
});

Use PaulGuo's jSQL, a SQL like database using javascript. For example:

var db = new jSQL();
db.create('dbname', testListData).use('dbname');
var data = db.select('*').where(function(o) {
    return o.name == 'Jacking';
}).listAll();

=Join(Parameters!Product.Label, vbcrfl) for new line

You don't give a reproducible example but your warning message tells you exactly what the problem is.

memb only has a length of 10. I'm guessing the length of dih_y2$MemberID isn't a multiple of 10. When using ==, R spits out a warning if it isn't a multiple to let you know that it's probably not doing what you're expecting it to do. == does element-wise checking for equality. I suspect what you want to do is find which of the elements of dih_y2$MemberID are also in the vector memb. To do this you would want to use the %in% operator.

dih_col <- which(dih_y2$MemeberID %in% memb)

You can use jQuery UI and do something like this

Html:

<button id="callConfirm">Confirm!</button>

<div id="dialog" title="Confirmation Required">
  Are you sure about this?
</div>?

Javascript:

$("#dialog").dialog({
   autoOpen: false,
   modal: true,
   buttons : {
        "Confirm" : function() {
            alert("You have confirmed!");            
        },
        "Cancel" : function() {
          $(this).dialog("close");
        }
      }
    });

$("#callConfirm").on("click", function(e) {
    e.preventDefault();
    $("#dialog").dialog("open");
});

?

Why don't you add the objects to be removed to another NSMutableArray. When you are finished iterating, you can remove the objects that you have collected.

I have not seen this approach anywhere:

int nbits(unsigned char v) {
    return ((((v - ((v >> 1) & 0x55)) * 0x1010101) & 0x30c00c03) * 0x10040041) >> 0x1c;
}

It works per byte, so it would have to be called 4 times for a 32-bit integer. It is derived from the sideways addition but uses two 32-bit multiplications to reduce the number of instructions to only 7.

Most current C compilers will optimize this function using SIMD (SSE2) instructions when it is clear that the number of requests is a multiple of 4, and it becomes quite competitive. It is portable, can be defined as a macro or inline function and does not need data tables.

This approach can be extended to work on 16 bits at a time, using 64-bit multiplications. However, it fails when all 16 bits are set, returning zero, so it can be used only when the 0xffff input value is not present. It is also slower due to the 64-bit operations and does not optimize well.

If you set the implicit wait of the driver, then call the findElement method on an element you expect to be on the loaded page, the WebDriver will poll for that element until it finds the element or reaches the time out value.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

For future search, you can change the sort statement:

>>> df.sort_values(by='Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A

I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering.

An object with a unencoded dataUri might have also fit your need if it was only to load a portion of data text:

The HTML <object> element represents an external resource, which can be treated as an image, a nested browsing context, or a resource to be handled by a plugin.

body {display:flex;min-height:25em;}
p {margin:auto;}
object {margin:0 auto;background:lightgray;}

<p>here My uploaded content: </p>
<object data='data:text/html,
  <style>

.table {
  display: table;
  text-align:center;
  width:100%;
  height:100%;
}

.table > * {
  display: table-row;
}

.table > main {
  display: table-cell;
  height: 100%;
  vertical-align: middle;
}
</style>


<div class="table">
  <header>
    <h1>Title</h1>
    <p>subTitle</p>
  </header>

  <main>
    <p>Collection</p>
    <p>Version</p>
    <p>Id</p>
  </main>

  <footer>
    <p>Edition</p>
  </footer>'>

</object>

But keeping your Iframe idea, You could also load your HTML inside your iframe tag and set it as the srcdoc value.You should not have to mind about quotes nor turning it into a dataUri but only mind to fire onload once.

The HTML Inline Frame element (<iframe>) represents a nested browsing context, embedding another HTML page into the current one.

Both iframe below will render the same, one require extra javascript.

example loading a full document :

body {
  display: flex;
  min-height: 25em;
}

p {
  margin: auto;
}

iframe {
  margin: 0 auto;
  min-height: 100%;
  background:lightgray;
}

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

also see:

CustomErrors mode="Off"

You can solve this error by adding an argumentless constructor to the base class (as shown below).

Cheers.

 abstract public class BaseClass {
        // ADD AN ARGUMENTLESS CONSTRUCTOR TO THE BASE CLASS
        public BaseClass(){
        }

        String someString;
        public BaseClass(String someString) {
            this.someString = someString;
        }
        abstract public String getName();
    }

public class ACSubClass extends BaseClass {
    public ASubClass(String someString) {
        super(someString);
    }
    public String getName() {
        return "name value for ASubClass";
    }
}

embed interop types visual studio should be set to false

I'm pretty sure this isn't a recommended practice anywhere in the sane world, but I like to line system includes up by filename length, sorted lexically within the same length. Like so:

#include <set>
#include <vector>
#include <algorithm>
#include <functional>

I think it's a good idea to include your own headers before other peoples, to avoid the shame of include-order dependency.

This worked for me using python 3.

It gets a list of URLs from the csv file and starts downloading them into a folder. In case the content or image does not exist it takes that exception and continues making its magic.

import urllib.request
import csv
import os

errorCount=0

file_list = "/Users/$USER/Desktop/YOUR-FILE-TO-DOWNLOAD-IMAGES/image_{0}.jpg"

# CSV file must separate by commas
# urls.csv is set to your current working directory make sure your cd into or add the corresponding path
with open ('urls.csv') as images:
    images = csv.reader(images)
    img_count = 1
    print("Please Wait.. it will take some time")
    for image in images:
        try:
            urllib.request.urlretrieve(image[0],
            file_list.format(img_count))
            img_count += 1
        except IOError:
            errorCount+=1
            # Stop in case you reach 100 errors downloading images
            if errorCount>100:
                break
            else:
                print ("File does not exist")

print ("Done!")

You can use a jQuery plugin (breedjs) that provides sort, filter and pagination:

HTML:

<table>
  <thead>
    <tr>
      <th sort='name'>Name</th>
      <th>Phone</th>
      <th sort='city'>City</th>
      <th>Speciality</th>
    </tr>
  </thead>
  <tbody>
    <tr b-scope="people" b-loop="person in people">
      <td b-sort="name">{{person.name}}</td>
      <td>{{person.phone}}</td>
      <td b-sort="city">{{person.city}}</td>
      <td>{{person.speciality}}</td>
    </tr>
  </tbody>
</table>

JS:

$(function(){
  var data = {
    people: [
      {name: 'c', phone: 123, city: 'b', speciality: 'a'},
      {name: 'b', phone: 345, city: 'a', speciality: 'c'},
      {name: 'a', phone: 234, city: 'c', speciality: 'b'},
    ]
  };
  breed.run({
    scope: 'people',
    input: data
  });
  $("th[sort]").click(function(){
    breed.sort({
      scope: 'people',
      selector: $(this).attr('sort')
    });
  });
});

Working example on fiddle

You can use e.g. this API if you would like to see bitString presentation of your numbers. Uncommons Math

Example (in jruby)

bitString = org.uncommons.maths.binary.BitString.new(java.math.BigInteger.new("12").toString(2))
bitString.setBit(1, true)
bitString.toNumber => 14

edit: Changed api link and add a little example

You can change time() to now() for it to work

from datetime import datetime, timedelta
datetime.now() + timedelta(hours=1)

try

npm install --force
npm install --legacy-peer-deps

Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).

$.each(json, function(arrayID,group) {
            console.log('<a href="'+group.GROUP_ID+'">');
    $.each(group.EVENTS, function(eventID,eventData) {
            console.log('<p>'+eventData.SHORT_DESC+'</p>');
     });
});

Should print out everything you were trying in your question.

http://jsfiddle.net/niklasvh/hZsQS/

edit renamed the variables to make it bit easier to understand what is what.

Keep it simple.

footer {
  bottom: 0;
  position: absolute;
}

You may need to also offset the height of the footer by adding a margin-bottom equivalent to the footer height to the body.

GPL-compiled ffmpeg can be used from non-GPL program (commercial project) only if it is invoked in the separate process as command line utility; all wrappers that are linked with ffmpeg library (including Microsoft's FFMpegInterop) can use only LGPL build of ffmpeg.

You may try my .NET wrapper for FFMpeg: Video Converter for .NET (I'm an author of this library). It embeds FFMpeg.exe into the DLL for easy deployment and doesn't break GPL rules (FFMpeg is NOT linked and wrapper invokes it in the separate process with System.Diagnostics.Process).

Download this JAR and add it to your libraries: http://java.net/projects/javamail/downloads/download/javax.mail.jar

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

ex: url/:id

var sample= app.controller('sample', function ($scope, $routeParams) {
  $scope.init = function () {
    var qa_id = $routeParams.qa_id;
  }
});

Here is one of the most efficient way, it works smoothly:

https://github.com/MikeOrtiz/TouchImageView

Place TouchImageView.java in your project. It can then be used the same as ImageView.

Example:

TouchImageView img = (TouchImageView) findViewById(R.id.img);

If you are using TouchImageView in xml, then you must provide the full package name, because it is a custom view.

Example:

    <com.example.touch.TouchImageView
            android:id="@+id/img”
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

All notifications (even other app notifications) can be removed via listening to 'NotificationListenerService' as mentioned in NotificationListenerService Implementation

In the service you have to call cancelAllNotifications().

The service has to be enabled for your application via:

‘Apps & notifications’ -> ‘Special app access’ -> ‘Notifications access’.

I added it for all fieldsets with

fieldset {
        border: 1px solid lightgray;
    }

I didnt work if I set it separately using for example

border-color : red

. Then a black line was drawn next to the red line.

1. Select all line you want comments

2. CTRL + /

The unix 'date' command is surprisingly versatile.

date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s"

Takes the output of date, which will be in the format defined by -f, and then prints it out (-j says don't attempt to set the date) in the form +%s, seconds since epoch.

((cd src-path && tar --remove-files -cf - files-to-move) | ( cd dst-path && tar -xf -))

Try this ...

  someArray = new Array();
  someArray[0] = 't5';
  someArray[1] = 'z12';
  someArray[2] = 'b88';
  someArray[3] = 's55';
  someArray[4] = 'e51';
  someArray[5] = 'o322';
  someArray[6] = 'i22';
  someArray[7] = 'k954';  

  var test =  findXX('o322'); 
  console.log(test);



function findXX(word)
{  
  for(var i in someArray){


    if(someArray[i] == word)
    {
      return someArray[i]; //<---  stop the loop!
    }   
  }
}

I wanted to do the same thing as, but I wanted to do it in the one file.

So the logic would be:

• if a script with my name is running, kill it, then exit
• if a script with my name is not running, do stuff

I modified the answer by Bakuriu and came up with this:

from os import getpid
from sys import argv, exit
import psutil  ## pip install psutil

myname = argv[0]
mypid = getpid()
for process in psutil.process_iter():
    if process.pid != mypid:
        for path in process.cmdline():
            if myname in path:
                print "process found"
                process.terminate()
                exit()

## your program starts here...

Running the script will do whatever the script does. Running another instance of the script will kill any existing instance of the script.

I use this to display a little PyGTK calendar widget which runs when I click the clock. If I click and the calendar is not up, the calendar displays. If the calendar is running and I click the clock, the calendar disappears.

There are several methods which can help, but this is one is using for loop.

import java.util.Arrays;

public class one_dimensional_for {

private static void count(int[] arr) {

    Arrays.sort(arr);

    int sum = 0, counter = 0;

    for (int i = 0; i < arr.length; i++) {
        if (arr[0] == arr[arr.length - 1]) {
            System.out.println(arr[0] + ": " + counter + " times");
            break;
        } else {
            if (i == (arr.length - 1)) {
                sum += arr[arr.length - 1];
                counter++;
                System.out.println((sum / counter) + " : " + counter
                        + " times");
                break;
            } else {
                if (arr[i] == arr[i + 1]) {
                    sum += arr[i];
                    counter++;
                } else if (arr[i] != arr[i + 1]) {
                    sum += arr[i];
                    counter++;
                    System.out.println((sum / counter) + " : " + counter
                            + " times");
                    sum = 0;
                    counter = 0;
                }
            }
        }
    }
}

public static void main(String[] args) {
    int nums[] = { 1, 1, 1, 1, 2, 2, 2, 3, 3, 4, 5, 5, 5, 5, 6 };
    count(nums);
}

This problem started when I did 'Remove Unused References'. The website still worked on my local machine, but did not worked on the server after publishing.

I fixed this problem by doing the following,

1. Open 'Package Manager Console' in Visual Studio
2. Uninstall-Package Microsoft.AspNet.Mvc
3. Install-Package Microsoft.AspNet.Mvc

Tested with PyCharm 4.0.6 (OSX 10.10.3) following this steps:

1. Click PyCharm menu.
2. Select Project Interpreter.
3. Select Gear icon.
4. Select More button.
5. Select Project Interpreter you are in.
6. Select Directory Tree button.
7. Select Reload list of paths.

Problem solved!

I like to know where does we use Native Methods

Ideally, not at all. In reality some functionality is not available in Java and you have to call some C code.

The methods are implemented in C code.

have you tried something like this:

if [ $# -eq 0 ] || [ $# -gt 1 ] 
then
 echo "$#"
fi

In Notepad++ v. 6.4.1 is this possibility in:Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input.

For auto-complete in code press Ctrl + Enter.

Here is my approach for importing .sql files to MS SQL:

1. Export table from MySQL with --compatible=mssql and --extended-insert=FALSE options:

   mysqldump -u [username] -p --compatible=mssql --extended-insert=FALSE db_name table_name > table_backup.sql

2. Split the exported file with PowerShell by 300000 lines per file:

   $i=0; Get-Content exported.sql -ReadCount 300000 | %{$i++; $_ | Out-File out_$i.sql}

3. Run each file in MS SQL Server Management Studio

There are few tips how to speed up the inserts.

Other approach is to use mysqldump –where option. By using this option you can split your table on any condition which is supported by where sql clause.

I alway do it like this:

$(document).ready(function(){
var maxChars = $("#sessionNum");
var max_length = maxChars.attr('maxlength');
if (max_length > 0) {
    maxChars.on('keyup', function(e){
        length = new Number(maxChars.val().length);
        counter = max_length-length;
        $("#sessionNum_counter").text(counter);
    });
}
});

Input:

<input name="sessionNum" id="sessionNum" maxlength="5" type="text">
Number of chars: <span id="sessionNum_counter">5</span>

I had the same problem with the package "tidyverse". I solved the problem with 1. uninstalling the package "Rcpp" and "tidyverse" 2. reinstalling "Rcpp" and answering the following questions during the installation process:

Do you want to install from sources the package which needs compilation? (Yes/no/cancel)

with

no

3. reinstalling "tidyverse".

Take a look at this article: Mapping Object Relationships

There are two categories of object relationships that you need to be concerned with when mapping. The first category is based on multiplicity and it includes three types:

*One-to-one relationships.  This is a relationship where the maximums of each of its multiplicities is one, an example of which is holds relationship between Employee and Position in Figure 11.  An employee holds one and only one position and a position may be held by one employee (some positions go unfilled).
*One-to-many relationships. Also known as a many-to-one relationship, this occurs when the maximum of one multiplicity is one and the other is greater than one.  An example is the works in relationship between Employee and Division.  An employee works in one division and any given division has one or more employees working in it.
*Many-to-many relationships. This is a relationship where the maximum of both multiplicities is greater than one, an example of which is the assigned relationship between Employee and Task.  An employee is assigned one or more tasks and each task is assigned to zero or more employees. 

The second category is based on directionality and it contains two types, uni-directional relationships and bi-directional relationships.

*Uni-directional relationships.  A uni-directional relationship when an object knows about the object(s) it is related to but the other object(s) do not know of the original object.  An example of which is the holds relationship between Employee and Position in Figure 11, indicated by the line with an open arrowhead on it.  Employee objects know about the position that they hold, but Position objects do not know which employee holds it (there was no requirement to do so).  As you will soon see, uni-directional relationships are easier to implement than bi-directional relationships.
*Bi-directional relationships.  A bi-directional relationship exists when the objects on both end of the relationship know of each other, an example of which is the works in relationship between Employee and Division.  Employee objects know what division they work in and Division objects know what employees work in them. 

Try this it will work --

if($('#EventStartTimeMin').val() === " ") {

    alert("Please enter start time!");

}

OK, as others note, the best thing to do is to use java.util.concurrent package. I highly recommend "Java Concurrency in Practice". It's a great book that covers almost everything you need to know.

As for your particular implementation, as I noted in the comments, don't start Threads from Constructors -- it can be unsafe.

Leaving that aside, the second implementation seem better. You don't want to put queues in static fields. You are probably just loosing flexibility for nothing.

If you want to go ahead with your own implementation (for learning purpose I guess?), supply a start() method at least. You should construct the object (you can instantiate the Thread object), and then call start() to start the thread.

Edit: ExecutorService have their own queue so this can be confusing.. Here's something to get you started.

public class Main {
    public static void main(String[] args) {
        //The numbers are just silly tune parameters. Refer to the API.
        //The important thing is, we are passing a bounded queue.
        ExecutorService consumer = new ThreadPoolExecutor(1,4,30,TimeUnit.SECONDS,new LinkedBlockingQueue<Runnable>(100));

        //No need to bound the queue for this executor.
        //Use utility method instead of the complicated Constructor.
        ExecutorService producer = Executors.newSingleThreadExecutor();

        Runnable produce = new Produce(consumer);
        producer.submit(produce);   
    }
}

class Produce implements Runnable {
    private final ExecutorService consumer;

    public Produce(ExecutorService consumer) {
        this.consumer = consumer;
    }

    @Override
    public void run() {
        Pancake cake = Pan.cook();
        Runnable consume = new Consume(cake);
        consumer.submit(consume);
    }
}

class Consume implements Runnable {
    private final Pancake cake;

    public Consume(Pancake cake){
        this.cake = cake;
    }

    @Override
    public void run() {
        cake.eat();
    }
}

Further EDIT: For producer, instead of while(true), you can do something like:

@Override
public void run(){
    while(!Thread.currentThread().isInterrupted()){
        //do stuff
    }
}

This way you can shutdown the executor by calling .shutdownNow(). If you'd use while(true), it won't shutdown.

Also note that the Producer is still vulnerable to RuntimeExceptions (i.e. one RuntimeException will halt the processing)

Here is how you can add an icon while creating an exe file from a Python file

• open command prompt at the place where Python file exist

• type:

  pyinstaller --onefile -i"path of icon"  path of python file
  

Example-

pyinstaller --onefile -i"C:\icon\Robot.ico" C:\Users\Jarvis.py

This is the easiest way to add an icon.

Your problem is the typo in the function CreateDectionary().You should change it to CreateDictionary(). collect2: error: ld returned 1 exit status is the same problem in both C and C++, usually it means that you have unresolved symbols. In your case is the typo that i mentioned before.

There is no specific method to read number of lines exposed by file object.

I guess the easiest way would be following:

lines =[]
with open(file_name) as f:
    lines.extend(f.readline() for i in xrange(N))

You can use Object.getOwnPropertyNames() to get all properties that belong to an object, whether enumerable or not. For example:

console.log(Object.getOwnPropertyNames(Math));
//-> ["E", "LN10", "LN2", "LOG2E", "LOG10E", "PI", ...etc ]

You can then use filter() to obtain only the methods:

console.log(Object.getOwnPropertyNames(Math).filter(function (p) {
    return typeof Math[p] === 'function';
}));
//-> ["random", "abs", "acos", "asin", "atan", "ceil", "cos", "exp", ...etc ]

In ES3 browsers (IE 8 and lower), the properties of built-in objects aren't enumerable. Objects like window and document aren't built-in, they're defined by the browser and most likely enumerable by design.

From ECMA-262 Edition 3:

Global Object
There is a unique global object (15.1), which is created before control enters any execution context. Initially the global object has the following properties:

• Built-in objects such as Math, String, Date, parseInt, etc. These have attributes { DontEnum }.
• Additional host defined properties. This may include a property whose value is the global object itself; for example, in the HTML document object model the window property of the global object is the global object itself.

As control enters execution contexts, and as ECMAScript code is executed, additional properties may be added to the global object and the initial properties may be changed.

I should point out that this means those objects aren't enumerable properties of the Global object. If you look through the rest of the specification document, you will see most of the built-in properties and methods of these objects have the { DontEnum } attribute set on them.

Update: a fellow SO user, CMS, brought an IE bug regarding { DontEnum } to my attention.

Instead of checking the DontEnum attribute, [Microsoft] JScript will skip over any property in any object where there is a same-named property in the object's prototype chain that has the attribute DontEnum.

In short, beware when naming your object properties. If there is a built-in prototype property or method with the same name then IE will skip over it when using a for...in loop.

In Python 3 this is the default behavior, but if you aren't using that you can import division like so:

>>> from __future__ import division
>>> 144/314
0.4585987261146497

Alternatively you can cast one of the variables to a float when doing your division which will do the same thing

sum = 144
women_onboard = 314
proportion_womenclass3_survived = sum / float(np.size(women_onboard))

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

You can think of reshaping that the new shape is filled row by row (last dimension varies fastest) from the flattened original list/array.

An easy solution is to shape the list into a (100, 28) array and then transpose it:

x = np.reshape(list_data, (100, 28)).T

Update regarding the updated example:

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (4, 2)).T
# array([[0, 1, 2, 3],
#        [0, 1, 2, 3]])

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (2, 4))
# array([[0, 0, 1, 1],
#        [2, 2, 3, 3]])

Final working solution using @Arrigo response and @Samitha Chathuranga comment, I'll put all together to build a full response for this question:

1. Suppose you have your project folder on PC;

2. Create a new repository on bitbucket:

3. Press on I have an existing project:

4. Open Git CMD console and type command 1 from second picture(go to your project folder on your PC)

5. Type command git init

6. Type command git add --all

7. Type command 2 from second picture (git remote add origin YOUR_LINK_TO_REPO)

8. Type command git commit -m "my first commit"

9. Type command git push -u origin master

Note: if you get error unable to detect email or name, just type following commands after 5th step:

 git config --global user.email "yourEmail"  #your email at Bitbucket
 git config --global user.name "yourName"  #your name at Bitbucket

Introduction

For reference I'd like to include my variation on VonC's answer. Keep in mind that I am using the MSys version of Git (1.6.0.2 at this time) with modified PATH, and running Git itself from Powershell (or cmd.exe), not the Bash shell.

I introduced a new command, gitdiff. Running this command temporarily redirects git diff to use a visual diff program of your choice (as opposed to VonC's solution that does it permanently). This allows me to have both the default Git diff functionality (git diff) as well as visual diff functionality (gitdiff). Both commands take the same parameters, so for example to visually diff changes in a particular file you can type

gitdiff path/file.txt

Setup

Note that $GitInstall is used as a placeholder for the directory where Git is installed.

1. Create a new file, $GitInstall\cmd\gitdiff.cmd

   @echo off
   setlocal
   for /F "delims=" %%I in ("%~dp0..") do @set path=%%~fI\bin;%%~fI\mingw\bin;%PATH%
   if "%HOME%"=="" @set HOME=%USERPROFILE%
   set GIT_EXTERNAL_DIFF=git-diff-visual.cmd
   set GIT_PAGER=cat
   git diff %*
   endlocal
   

2. Create a new file, $GitInstall\bin\git-diff-visual.cmd (replacing [visual_diff_exe] placeholder with full path to the diff program of your choice)

   @echo off
   rem diff is called by git with 7 parameters:
   rem path old-file old-hex old-mode new-file new-hex new-mode
   echo Diffing "%5"
   "[visual_diff_exe]" "%2" "%5"
   exit 0
   

3. You're now done. Running gitdiff from within a Git repository should now invoke your visual diff program for every file that was changed.

Daniel's answer was good except I had to change this code...

    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

to this code...

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
    SchemeRegistry registry = ccm.getShemeRegistry()
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

to get it to work.

I prefer putting a curly brace. But sometimes, ternary operator helps.

In stead of :

int x = 0;
if (condition) {
    x = 30;
} else {
    x = 10;
}

One should simply do : int x = condition ? 30 : 20;

Also imagine a case :

if (condition)
    x = 30;
else if (condition1)
    x = 10;
else if (condition2)
    x = 20;

It would be much better if you put the curly brace in.

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

Apparently the information is available using the Google Directions API in its professional edition Maps for work. According to the API's documentation:

Note: Maps for Work users must include client and signature parameters with their requests instead of a key.
[...]
duration_in_traffic indicates the total duration of this leg, taking into account current traffic conditions. The duration in traffic will only be returned if all of the following are true:

• The directions request includes a departure_time parameter set to a value within a few minutes of the current time.
• The request includes a valid Google Maps API for Work client and signature parameter.
• Traffic conditions are available for the requested route.
• The directions request does not include stopover waypoints.

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

A little piece of PHP to get the server to populate a JavaScript variable is quick and easy:

var my_javascript_variable = <?php echo json_encode($_POST['my_post'] ?? null) ?>;

Then just access the JavaScript variable in the normal way.
