+ * TMultiplexedProtocol is a protocol-independent concrete decorator that allows a Thrift
+ * client to communicate with a multiplexing Thrift server, by prepending the service name
+ * to the function name during function calls.
+ *
+ * NOTE: THIS IS NOT TO BE USED BY SERVERS.
+ * On the server, use TMultiplexedProcessor to handle requests from a multiplexing client.
+ *
+ * This example uses a single socket transport to invoke two services:
+ *
+ * TSocketTransport transport = new TSocketTransport("localhost", 9090);
+ * transport.open();
+ *
+ * TBinaryProtocol protocol = new TBinaryProtocol(transport);
+ *
+ * TMultiplexedProtocol mp = new TMultiplexedProtocol(protocol, "Calculator");
+ * Calculator.Client service = new Calculator.Client(mp);
+ *
+ * TMultiplexedProtocol mp2 = new TMultiplexedProtocol(protocol, "WeatherReport");
+ * WeatherReport.Client service2 = new WeatherReport.Client(mp2);
+ *
+ * System.out.println(service.add(2,2));
+ * System.out.println(service2.getTemperature());
