Detailed Description

callback with 0 parameter(s) and without returnvalue.

Date:

2002

Author:

Bram de Greve [Bramz] (contact: bramz@users.sourceforge.net)

It's a single object that can hold a reference to a free function or an object/(const) method pair. Once the callback is constructed, it works completely transparent. All it shows to the client is a function that takes one parameter but gives no returnvalue.
