RE: [cdt-dev] AST: How to discover now whether ICPPClassScope isICPPTemplateScope?
|
Hi,
Your best choice is to work with the bindings rather than with the
scopes.
In CDT 6.0 we have the method IBinding.getOwner() for that. In older CDT
versions you only have ICPPMember.getClassOwner(), which provides the
class for the members. In your case this should be sufficient.
If you do need or want to work with the scope, you can also use
ICPPClassScope.getClassType() to find the binding for the class scope.
The binding will tell you whether you are looking at a template or not.
The change is not a bug, in fact the template scopes itself caused lots
of issues because they destroy the tree structure of scopes. The
motivation
for the change is discussed here:
