Detailed Description

This provides a basic interface for an observable entity and some helper functions.

Parameters:

Listener The listener type that can listen on this subject.

Constructor & Destructor Documentation

template<class Listener>

virtual psynth::base::subject_base< Listener >::~subject_base ( ) [inline, virtual]

Virtual destructor.

template<class Listener>

virtual void psynth::base::subject_base< Listener >::add_listener ( Listener & l ) [pure virtual]

Must connect all subject signals with pairing methods on the listener side.

Parameters:

l	The listener to connect.

template<class Listener>

virtual void psynth::base::subject_base< Listener >::del_listener ( Listener & l ) [pure virtual]

Must disconnect the listener from the signals in this subject.

Parameters:

l	The listener to disconnect.

template<class Listener >

template<class Signal , class Slot >

void psynth::base::subject_base< Listener >::remove_slot	(	Signal &	sig,
		const Slot &	s
	)		`[protected]`

Helper function that will aid derived classes on the implementation of del_listener.

It disconnect a specific slot from a signal.

Parameters:

sig	The signal.
s	The slot.

Is this function useless under boost::signals ??

This also relies on equality of objects generated by boost::bind, make sure that our asumptions are right.
