Protocol buffers implement their own serialization routines: the writeTo(OutputStream output) method will write the binary format to the OutputStream. From a socket, just do:
MyProtoBuf pb = new MyProtoBuf; ... pb.writeTo(socket.getOutputStream()); On Wed, Dec 2, 2009 at 7:47 AM, Nigel Pickard <pickard.ni...@gmail.com>wrote: > OK, so far I like GPB.
