Parameters

TUint aEventClass

event class to be checked for listeners.

Notify(TUint, TUint, const void *)

void	Notify	(	TUint	aEventClass,
			TUint	aEventType,
			const void *	aData
		)	[pure virtual]

Parameters

TUint aEventClass	event class, determines which listeners are notified.
TUint aEventType	event type code, specific for given class.
const void * aData	Event type specific data. The data is passed to all notified listeners.

RegisterListener(MEventListener *, TUint)

TInt	RegisterListener	(	MEventListener *	aListener,
			TUint	aEventClass
		)	[pure virtual]

If a listener wants to register for several event classes, this method needs to be called a multiple times.

Parameters

MEventListener * aListener	Pointer to listener instance
TUint aEventClass	Event class for which notifications are to be sent.

RemoveListener(MEventListener *, TUint)

TInt	RemoveListener	(	MEventListener *	aListener,
			TUint	aEventClass = 0
		)	[pure virtual]

Parameters

MEventListener * aListener	Pointer to listener instance to be unregistered
TUint aEventClass = 0	Event class which is unregistered. If the listener was registered to other event classes, it remains registered there. If this parameter is omitted or 0 is given, then the listener is unregistered from all event classes (useful for cleanup).
