This worked nicely
OutputStream output = new OutputStream() {
private StringBuilder string = new StringBuilder();
@Override
public void write(int b) throws IOException {
this.string.append((char) b );
}
//Netbeans IDE automatically overrides this toString()
public String toString() {
return this.string.toString();
}
};
method call =>> marshaller.marshal( (Object) toWrite , (OutputStream) output);
then to print the string or get it just reference the "output" stream itself
As an example, to print the string out to console =>> System.out.println(output);
FYI: my method call marshaller.marshal(Object,Outputstream) is for working with XML. It is irrelevant to this topic.
This is highly wasteful for productional use, there is a way too many conversion and it is a bit loose. This was just coded to prove to you that it is totally possible to create a custom OuputStream and output a string. But just go Horcrux7 way and all is good with merely two method calls.
And the world lives on another day....
