google.com/p/protobuf/">Google Protocol Buffers {@link Message} and {@link MessageLite} into a{@link ChannelBuffer}. A typical setup for TCP/IP would be:

 {@link ChannelPipeline} pipeline = ...;// Decoders pipeline.addLast("frameDecoder", new  {@link LengthFieldBasedFrameDecoder}(1048576, 0, 4, 0, 4)); pipeline.addLast("protobufDecoder", new  {@link ProtobufDecoder}(MyMessage.getDefaultInstance())); // Encoder pipeline.addLast("frameEncoder", new  {@link LengthFieldPrepender}(4)); pipeline.addLast("protobufEncoder", new  {@link ProtobufEncoder}());

and then you can use a {@code MyMessage} instead of a {@link ChannelBuffer}as a message:

 void messageReceived( {@link ChannelHandlerContext} ctx, {@link MessageEvent} e) {MyMessage req = (MyMessage) e.getMessage(); MyMessage res = MyMessage.newBuilder().setText( "Did you say '" + req.getText() + "'?").build(); ch.write(res); }
