clang AST visitor extra arguments -


currently clang's traverse* functions accept ast nodes sole argument. wondering if there way pass 1 or more arguments traverse* functions in clang's astvisitor.

for example, let's have binaryoperator , want pass state when call traversestmt on lhs , rhs:

traversestmt(lhs, state); ... traversestmt(rhs, state);

is there way achieve this?

one way avoid passing argument maintain local stack within astvisitor object. ugly!

thanks.
