Detailed Description

std::ostringstream wrapper.

ostringstream's operator<< doesn't return a ostringstream&. It returns an ostream& instead. This is unfortunate, because it means that you can't do something like this: (ostringstream() << n).str() to convert an integer to a string, all in one line instead you have to use this far more tedious approach: ostringstream s; s << n; s.str(); This class corrects this shortcoming, allowing something like this: string result = (formatter() << "blah " << n << x << " blah").str();

Actually, due to the ref qualified versions below, you can get away with this

string result = formatter() << "blah " << n << x << " blah";
