Question

I have the following protoc file:

message DataChunk{
    required bool isHash=1;
    required int64 hash=2;
    required string data=3;
}

message responseBody{
    repeated DataChunk dataChunk=1;
}

And I have the following C++ function:

void eamorr(string data){   //data is a protocol buffer stream converted to a string
    responseBody rb;

    rb=some_function_of(data);   //what to do here?
}

The string “data” was created using:

...
std::ostringstream stream;
rb.SerializeToOstream(&stream);
string protobufStream = stream.str();
...

My question is: how do I convert a string to a protoc object so I can access the member elements? Please bear in mind that I’m very new to C++.

You can use

rb.ParseFromString(data)
