[cdt-dev]: How does one get the namespace for a C++ declaration in the A

[Jeff Johnston <jjohnstn@xxxxxxxxxx>]

I have the following C++ code:

#include <iostream>
#include <string>
using namespace std;

int main() {
   string *a = new string("abc");
   a->size();
   a->append("a", 2);
   std::cout << "!!!Hello World!!!" << std::endl; // prints !!!Hello 
World!!!
   return 0;
}

I have written a libstdc++ hover help plugin which is generated from the 
actual libstdc++ documentation.

When a user hovers over the "append" method above, I backtrack and find 
"a".  I use a SharedASTJob to  get the enclosing ASTName via:

ast.getNodeSelector(null).findEnclosingName();

I then do a second SharedASTJob to getDeclarationsinAST() for the 
binding of "a".  This gets me an IASTSimpleDeclaration to which I 
perform ast.getDeclSpecifier().  This gets me an  IASTNamedTypeSpecifier 
to which I get the name via getName().

The problem for the above case is that I only get "string".  I need to 
get: "std::string" or "std::basic_string<char, etc..>" as I have a map 
of fully-qualified class and typedef names to which I can resolve the 
online help.  I use a separate SharedASTJob to resolve to the correct 
append method signature and this is working great.  For example, if the 
above test is changed to use std::string explicitly, everything works fine.

So how do I resolve the namespace for the declaration of a?  I can send 
code off-line if further details are needed.

Thanks,
