Examples of OutputRepresentation

org.restlet.representation.OutputRepresentation
Representation based on a BIO output stream. This class is a good basis to write your own representations, especially for the dynamic and large ones.

For this you just need to create a subclass and override the abstract Representation.write(OutputStream) method. This method will later be called back by the connectors when the actual representation's content is needed. @author Jerome Louvel
