13  * This utility class adapts a <code>MultiplexSocketConnector</code> to a
14  * <code>java.net.ServerSocket<code>. That means that a socket connector, that
15  * was previously created with a multiplex server socket, can be used as
16  * a traditionnal server socket. This adapter can be useful when integrating
17  * the multiplex module into existing code that rely on the <code>java.net.ServerSocket<code>
18  * object.<p>
19  *
20  * Note that the following methods are not supported:
21  * <ul>
22  * <li>bind(SocketAddress endpoint)</li>
23  * <li>bind(SocketAddress endpoint, int backlog)</li>
24  * <li>setSoTimeout(int timeout)</li>
25  * <li>setReuseAddress(boolean on)</li>
26  * <li>setReceiveBufferSize(int size)</li>
27  * </ul><p>
28  *
29  * Calling any of these methods will result in an <code>UnsupportedOperationException</code>
30  * beign thrown.
