Hello folks,

I have a 2D array emulation in my proto file.

In C++, after generating the protobuf files,  I see I have methods declared 
for adding "columns" (add_columns) in the pb.h  without any parameters. 
 Also there is another method declared to add "records" (add_records) in 
the pb.h without any parameters.  

In Java the generated functions accept message builder as a parameter and 
it is easy to construct the request.

In C++ for fields in proto file with standard datatypes like string and int 
I have setters that accept the string and int as parameters.  For type 
google.protobuf.Value or type Record, I have no parameters. 

Here is the code.  How can I populate the request with the "columns" values 
of type google.protobuf.Value and "records" values of type Record?  Any 
help is appreciated.  Thank you !

message DataMessage {

        int32 Status = 1;

        int32 Entries = 2;

        repeated string columnNames = 4;


        // By repeating this message, we somewhat emulate a 2D array

        message Record {

                repeated google.protobuf.Value columns = 1;

        }

        repeated Record records = 5;

}
