array getListeners(string $eventName = null)
Gets the listeners of a specific event or all listeners sorted by descending priority.
int|null getListenerPriority(string $eventName, callable $listener)
Gets the listener priority for a specific event.
Returns null if the event or the listener does not exist.
bool hasListeners(string $eventName = null)
Checks whether an event has any registered listeners.
Event dispatch(string $eventName, Event $event = null)
Dispatches an event to all registered listeners.
