Please advise. > You're not missing anything; the standard wire format for protocol buffers does not include the names of anything, only the fields and types. Your communication protocol will need some higher level coordination to handle what types of message should be sent. One possible way of encoding this sort of information into a protocol buffer is to use a container message, such as message OuterMessage { oneof messages { Msg1 msg1 = 1; Msg2 msg2 = 2; } } Where each possible message is specified in the oneof group. Then in your C++ code handling the received outer message, you can switch on the result of messages_case() to know which inner message was actually sent. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
