Detailed Description

Data collector stream.

A class derived from std::ostringstream that allows to collect data via a temporary returned object. To facilitate this it stores a callback that is used to pass the collected data to its creator on destruction.

In order to avoid passing the same data twice, copy construction is forbidden and only move construction is allowed.
