shouldVisitDecl()

bool RScanner::shouldVisitDecl ( clang::NamedDecl * D )

private

Whether we can actually visit this declaration, i.e.

if it is reachable via name lookup.

RScanner shouldn't touch decls for which this method returns false as we call Sema methods on those declarations. Those will fail in strange way as they assume those decls are already visible.

The main problem this is supposed to prevent is when we use C++ modules and have hidden declarations in our AST. Usually they can't be found as they are hidden from name lookup until their module is actually imported, but as the RecursiveASTVisitor is not supposed to be restricted by lookup limitations, it still reaches those hidden declarations.
