[c++] How to access nested message defined inside of another message?

[rkr...@gmail.com]

I'm having a hard time figuring out how to access a nested message that's defined within a message (inline definition). However, I can easily access a nested message that's defined outside of the message.

What I mean is:

message outer
{
    global foo = 1;
    message inner
    {
        int64 j = 2;
    }
}

message global
{
    int64 k = 3;
}

Accessing the globally-defined message works fine:

std::cout << "k is " << request.foo().k() << "\n";

But I cannot access the internally-defined message via:

std::cout << "j is " << request.inner().j() << "\n";

I get a compiler message of

error: invalid use of 'helloworld::HelloRequest::inner'

I've even tried:

std::cout << "j is " << request.j() << "\n"

but of course there's no member "j" in "request".

I'm sure it's something silly that I'm doing :-) [It would be most useful to put this answer in https://developers.google.com/protocol-buffers/docs/reference/cpp-generated near the section with the text "A message can be declared inside another message. For example: message Foo { message Bar { } } " :-)

Thanks in advance!

the inner message defines a class. if you want  a field of type inner you have a define that too
