[cfe-dev] How to print the forward declaration of an object visited through RecursiveASTVisitor ?

[Manasij Mukherjee]

As a follow up to this question, I am now generating the
(forward)declarations manually, not having found anything in the API to do
it.
The only thing that I can't get working is the way to get the type name of
a non-type template parameter.
If I have:
template<typename T, typename U, int V> class foo
{};
>From where do I get the string "int" when overriding VisitClassTemplateDecl
?

I can get the names of the identifiers T, U, V as:

    clang::TemplateParameterList* tl=Declaration->getTemplateParameters();
    for(auto it=tl->begin();it!=tl->end();++it) {
        p->getName();
    }

But I can't find any obvious way to get its type as a string.
p->getDeclKindName() only returns "TemplateTypeParm" or
"NonTypeTemplateParm"
