Re: AW: [cdt-dev] Methode Visibility in AST

[Andrew Niefer <aniefer@xxxxxxxxxx>]

Hi Leo,
Just a quick note about your getDeclarationName.
 The IASTName you want is on the inner-most nested declarator, if
the declaration in question is something like a pointer to function "void
(*pf) ();" then your code will return the wrong IASTName.
There is a method CPPVisitor#getMostNestedDeclarator
that you can use:
        return
CPPVisitor.getMostNestedDeclarator( declarators[0] ).getName();

Thank you Doug and Andrew,
I've found the solution with your help. Following code snippet will perhaps
help somebody how search for something similar.

If you have the IASTName for the method, you can resolveBinding() on it
to
get at the ICPPMethod binding object. From there you can get the visibility.

Hi all,
We currently working hard to implement refactoring with the DOM-AST. Is
there 
currently a possibility to get the visibility of a method? If not, we try
to

implement this.
Regards,
Leo
