public class DelegatingOutputStream
extends java.io.OutputStream
The class DelegatingOutputStream itself simply overrides all methods of OutputStream with
versions that pass all requests to the underlying output stream. Subclasses of DelegatingOutputStream
may further override some of these methods as well as provide additional methods and fields.
Note: The only difference to FilterOutputStream is that DelegatingOutputStream
does not override OutputStream.write(byte[]) or OutputStream.write(byte[], int, int) but rather exposes the original
implementations of InputStream which call write(int) instead of their delegate counterparts.

public DelegatingOutputStream(java.io.OutputStream out)
out - the underlying output stream to be assigned to the field this.out for later use, or
null if this instance is to be created without an underlying stream.public java.io.OutputStream getDelegate()
public void write(int b)
throws java.io.IOException
byte to this output stream.
The write method of DelegatingOutputStream calls the write method of its
underlying output stream, that is, it performs out.write(b).
Implements the abstract write method of OutputStream.

The flush method of DelegatingOutputStream calls the flush method of its
underlying output stream.

The close method of DelegatingOutputStream calls its flush method, and then
calls the close method of its underlying output stream.
