Detailed Description

Like std::stringstream, copying to a given target string at destruction.

This is a convenience helper, allowing the use of:

Targeted_stringstream(s) << foo << bar << baz;

instead of:

std::stringstream stream;
stream << foo << bar << baz;
s.assign(stream.str());

This can, for instance, be used by a class to export a stream interface to update private string members.
