Clang tooling, check if final or override

Question

Is there a "clang way" to check if CXXMethodDecl is specified with override or final keywords?

I can check it by std::string::find(" override") for the string representing CXXMethodDecl, but this way looks a little ugly.

Answer 1

It turned out that that final and override are hidden in the attributes of the clang::Decl. So the underlying code checks method for final.

bool FinalReplacer::VisitCXXMethodDecl(CXXMethodDecl *methodDecl) {
    auto pos = find_if(methodDecl->attr_begin(), methodDecl->attr_end(), [](Attr *a) {
        return (a->getKind() == attr::Kind::Final);
    });
    if (pos != methodDecl->attr_end()) {
        //Do something here.
    }
    return true;
}

Similarly for override attribute is attr::Kind::Override.
