@Override
    protected Object getSourceDelegate( MessageConnection source ) {
        return delegate;
    }
Creates a MessageListener that will forward mapped message types
 to methods of the specified object.
 If automap is true then all methods with the proper signature will
 be mapped.
 <p>Methods of the following signatures are allowed:
 <ul>
 <li>void someName(S conn, SomeMessage msg)
 <li>void someName(Message msg)
 </ul>
 Where S is the type of MessageConnection and SomeMessage is some
 specific concrete Message subclass.
