[cfe-dev] How can I check if the qualifiers of a type has a class in it?

[Manasij Mukherjee]

I have a FunctionDecl while overriding VisitFunctionDecl of ASTVisitor.

I did Decl->getQualifier()->getKind() == NestedNameSpecifier::TypeSpec
But it segfaults in getKind
So, I am probably calling getQualifier from the wrong thing.
Decl->getQualifier() is always returning a null value.

When is a valid qualifier returned?

My input code is:
namespace test { //nested name specifier
  class HasSubType {
  public:
    class SubType {};
  };
  HasSubType::SubType FunctionUsingSubtype(HasSubType::SubType s){return s;}
  extern HasSubType::SubType variable;
  HasSubType FunctionNotUsingSubType(HasSubType h){return h;}
}
I want to filter out FunctionUsingSubType and the variable.


Thanks
