[grpc-io] Re: How to Pass a a list of data like array or vector (using repeated in protobuf file) from server to client using stream data.

[rohit nv]

Thanks for the reply..

I have one more doubt. Can we use a repeated (vector or map ) to send data 
for a streamed communication.

e.g 


syntax = "proto3";

import "google/protobuf/empty.proto";

message Dummy {
  string foo = 1;
  repeated int bar = 2;
}

message DummyList {
  Dummy dummy = 1;
}

service DummyService {
  rpc getDummyListWithRepeated(google.protobuf.Empty) returns (DummyList) {}
}

Want to know how can I use the DummyList in a c++ project  to copy the 
value from a  vector of integer values into bar field of Dummy message.



Thank you..!

Hi, 

It seems like you are looking for help with usage of protobuf for repeated 
fields. 

protobuf has pretty good documentations for such stuff - 
https://developers.google.com/protocol-buffers/docs/reference/cpp-generated#repeatedmessage
 
Hope that helps. Cheers!
