Maybe you can try CXXRecordDecl::fields()?

Depending on the context of your program you can either try to 1) traverse the fields within VisitCXXRecordDecl() or 2) use the FieldDecl::getParent() method within VisitFieldDecl() to figure out which CXXRecordDecl the FieldDecl belongs to (if any).

I don't know anything about RecursiveASTVisitor so there might be a way to do what you want there. If you need to traverse the AST "manually" there's code in clang/lib/CodeGen/CGDebugInfo.cpp (look for CGDebugInfo::CollectRecordFields) that could be instructive. Note that a VarDecl describes a static data member, while a FieldDecl describes a normal data member. --paulr > > I hope I have stated my problem understandable..- > > > Thanks > > Marcel > ________________________ > cfe-dev mailing list > cfe-dev at lists.llvm.org > https://urldefense.com/v3/_https://lists.llvm.org/cgi- > bin/mailman/listinfo/cfe-dev;!!JmoZiZGBv3RvKRSx!sAghJD5ak8TBfwxlN3- > clB7IHmStNEf-qYGycEskAWJCHsfocgsXmtBh2CP25GHZAA$
