/**
 * An <code>RMISocketFactory</code> instance is used by the RMI runtime
 * in order to obtain client and server sockets for RMI calls.  An
 * application may use the <code>setSocketFactory</code> method to
 * request that the RMI runtime use its socket factory instance
 * instead of the default implementation.
 *
 * <p>The default socket factory implementation creates a direct
 * socket connection to the remote host.
 *
 * <p>The default socket factory implementation creates server sockets that
 * are bound to the wildcard address, which accepts requests from all network
 * interfaces.
 *
 * @implNote
 * <p>You can use the {@code RMISocketFactory} class to create a server socket that
 * is bound to a specific address, restricting the origin of requests. For example,
 * the following code implements a socket factory that binds server sockets to an IPv4
 * loopback address. This restricts RMI to processing requests only from the local host.
 *
 * <pre>{@code
 *     class LoopbackSocketFactory extends RMISocketFactory {
 *         public ServerSocket createServerSocket(int port) throws IOException {
 *             return new ServerSocket(port, 5, InetAddress.getByName("127.0.0.1"));
 *         }
 *
 *         public Socket createSocket(String host, int port) throws IOException {
 *             // just call the default client socket factory
 *             return RMISocketFactory.getDefaultSocketFactory()
 *                                    .createSocket(host, port);
 *         }
 *     }
 *
 *     // ...
 *
 *     RMISocketFactory.setSocketFactory(new LoopbackSocketFactory());
 * }</pre>
 *
 * Set the {@code java.rmi.server.hostname} system property
 * to {@code 127.0.0.1} to ensure that the generated stubs connect to the right
 * network interface.
