$event
parameter of EventManager::getListeners()
mandatoryWhen calling EventManager::getListeners()
you need to specify the event that
you want to fetch the listeners for. Call getAllListeners()
instead if you
want to access the listeners of all events.
EventManager::getListeners()
without an event nameWhen calling EventManager::getListeners()
without an event name, all
listeners were returned, keyed by event name. A new method getAllListeners()
has been added to provide this functionality. It should be used instead.
