Re: [cdt-dev] CDT DOM Usage

[Andrew Niefer <aniefer@xxxxxxxxxx>]

A couple of comments:
1.  Use the interfaces instead
of the implementing classes, ie ICPPClassType instead of CPPClassType.
 This becomes a bigger issue when dealing with code that has templates.
2.  You can check IASTName.isDeclaration(),
isDefinition, isReference, to determine the relationship between the IASTName
and the resulting binding.  There is one binding for a class A, and
all declarations and references to A will return the same binding.
3.  Realize you are parsing the
entire translation unit (including headers) and not just your file.  IASTNode
(which IASTName extends) has methods for getting the the containg file
or location of the IASTName.
