$eventKey
The event unique identifier name with which the callback has been associated, or the $listener you want to remove.
$callable
optional null on( string|Cake\Event\EventListenerInterface|null $eventKey null , array|callable $options [] , callable|null $callable null )
Adds a new listener to an event.
A variadic interface to add listeners that emulates jQuery.on().
Binding an EventListenerInterface:
$eventManager->on($listener);
Binding with no options:
$eventManager->on('Model.beforeSave', $callable);
Binding with options:
$eventManager->on('Model.beforeSave', ['priority' => 90], $callable);
Cake\Event\EventListenerInterface
|null $eventKey
optional null The event unique identifier name with which the callback will be associated. If $eventKey is an instance of Cake\Event\EventListenerInterface its events will be bound using the implementedEvents
methods.
$options
optional [] Either an array of options or the callable you wish to bind to $eventKey. If an array of options, the priority
key can be used to define the order. Priorities are treated as queues. Lower values are called before higher ones, and multiple attachments added to the same priority queue will be treated in the order of insertion.
$callable
optional null When event key is missing or callable is not an instance of Cake\Event\EventListenerInterface.
