Detailed Description

This is a very simple class that implements OutputBase::writeItemsetAndCounter by the call of an STL' copy procedure.

The main purpose of this class is to provide a basic class for the tests. If the size of the output is large, and the performance is important, you should use a BufferedOutput like NormalBufferedOutput. For more information about the performance of the different output classes test_results.html.
