notify()

ilObjMediaPool::notify	(		$a_event,
			$a_ref_id,
			$a_parent_non_rbac_id,
			$a_node_id,
			$a_params = 0
	)

notifys an object about an event occured Based on the event happend, each object may decide how it reacts.

If you are not required to handle any events related to your module, just delete this method. (For an example how this method is used, look at ilObjGroup)

public

Parameters

string	event
integer	reference id of object where the event occured
array	passes optional parameters if required

Returns

boolean
