afterDispatch()source public

afterDispatch( Cake\Event\Event $event )

Method called after the controller served a request and generated a response. It is possible to alter the response object at this point as it is not sent to the client yet.

If false is returned, the event will be stopped and no more listeners will be notified. Alternatively you can call $event->stopPropagation() to achieve the same result.

Parameters

Cake\Event\Event $event

container object having the request and response keys in the data property.

handle()source public

handle( Cake\Event\Event $event )

Handler method that applies conditions and resolves the correct method to call.

Parameters

Cake\Event\Event $event
The event instance.

Returns

mixed

implementedEvents()source public

implementedEvents( )

Returns the list of events this filter listens to. Dispatcher notifies 2 different events Dispatcher.before and Dispatcher.after. By default this class will attach preDispatch and postDispatch method respectively.

Override this method at will to only listen to the events you are interested in.

Returns
