</div>You don't have to traverse it all. You can implement your own<br>
TraverseDecl that (roughly) checks which file a Decl is in, returning<br>
true early if it's not in a file of interest and calling the default<br>
RecursiveASTVisitor::TraverseDecl otherwise.<br></blockquote><div><br></div><div>While possible, I'd advise against doing your own AST traversal - it is quite an undertaking, and very easy to get wrong.</div><div> <br>
