RE: [ALACPP] container streaming, sigh |
Well, I'd just create some global function, so: Namespace _Utility { void Serialize(ostream &lhs, const string &rhs) { lhs << rhs << std::endl; } } ostream& operator << (ostream& str, const vector<string> & rhs) { for_each(rhs.begin(), rhs.end(), boost::bind(&_Utility::Serialize, str, _1)); return str; } You still have the function, but you don't need all the reification overhead - bind does that for you.
