[aspectc-user] Modifying C++ code?

[Matthias Urban]

Hi,

That's true, these methods were added later. But that's no problem,
without these methods the code looks like this:

void serialize(Puma::CTree* tree, std::ostream& os) {
  Puma::Token* token = tree->token();
  Puma::Token* end = tree->end_token();
  while (token) {
    os << token->text();
    if (token == end) {
      break;
    }
    token = (Puma::Token*)((Puma::Unit*)token->belonging_to())->next(token);
  }
}
