Is it possible to use external enums (outside message definitions) with protocol buffers?

Question

I need to store enumns inside a PB message that are defined outside the PB message definitions. Is it possible at all & how?

Answer 1

It's possible. Look at this thread for more info. I like the suggestion to define enums in a seperate .proto file. like

enums.proto

enum A
{ 
   FIRST = 1;
   SECOND = 2;
}

enum B { ... }

other.proto

import "enums.proto";

message SOMEMESSAGE
{
  required A myenum = 1;
}
