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
andresponse
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
mixedimplementedEvents()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
arrayImplementation of
Cake\Event\EventListenerInterface::implementedEvents()
matches()source public
matches( Cake\Event\Event $event )
Check to see if the incoming request matches this filter's criteria.
Parameters
-
Cake\Event\Event
