Detailed Description

This struct implements a callable object (a functor, basically).

An instance can be passed in where a boost::function1<bool, void*> is expected. In vrj:PerformanceMediator::loadPerfPlugin(), instances are used to handle dynamic loading of plug-ins via vpr::LibraryLoader.

This will be invoked as a callback by methods of vpr::LibraryLoader.

Parameters:

func
