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


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.

public IASTName getDeclarationName(IASTSimpleDeclaration astNode) {
                IASTDeclarator[] declarators = astNode.getDeclarators();
                if(declarators != null && declarators.length > 0){
                                 return declarators[0].getName();
                } else {

public int getVisibility(){

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
