Detailed Description

template<typename R>
class lass::util::CallbackR0< R >

callback with 0 parameters but with 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 0 parameter(s) and gives a returnvalue.
