Hi,
I heard about this google protobuf stuff for the first time when I was
assigned a project. Did some reading and when I went to add some variable
in the google message structure, no setters were generated for this new
variable. After doing extensive research, I thought I need to use mutable()
instead. But when I try to call this function within my class, compiler
complains. I am enclosing my code snapshot if it helps. Thank you very
much for your time.

message Data1 {
optional string A1 = 1;
optional string A2 = 2;
optional string A3 = 3;
//here x,y, z are different namespaces.
optional x::y::z::*RegionData regiondata1* = 4; //new
variable added... //RegionData is enum defined in some other class.
}
In my class Foo
--------------------------------
File: Foo.hpp
-------------------------------
Class Foo {
Data1 instance1;
}
--------------------------------------
File: Foo.cpp
---------------------------------------
Void Foo :: initialize() {
int regiondata = 0;
//trying to set the value of region;
//get the region value from some other source.
//call protobuf method to set the value..
instance1.mutable_regiondata1()->set_allocated_regiondata(®ionData);
//compile error ...not able to recognize this function
}
*Note:*
//compile fails saying class Data1 has no member named mutable_regiondata1()
///There are no regular setter functions generated for this variable.
//So after doing extensive research, I came to the conclusion that I need
to use this way. Not sure what I am doing wrong here.
//Any pointers to help me out is highly appreciated since I am running
closer to deadline.
This is the generated *Base.pb.cc* file
