Only one.



How can I define a service which will accept both arguments:


Create a union message, or define two RPCs. Unions:

http://code.google.com/apis/protocolbuffers/docs/techniques.html#union

Two RPCs:

service Service {
  rpc sendObject1(Object1) returns (Result1);
  rpc sendObject2(Object2) returns (Result2);
}

Hope this helps,

Evan
