+{ 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 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:
+
+      TSocket transport = new TSocket("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());
+
+}
