class TraceableEventDispatcher extends TraceableEventDispatcher
Collects some data about event listeners.
This event dispatcher delegates the dispatching to another one.
__construct(EventDispatcherInterface $dispatcher, Stopwatch $stopwatch, LoggerInterface $logger = null) Constructor. | from TraceableEventDispatcher | |
addListener(string $eventName, callable $listener, int $priority) Adds an event listener that listens on the specified events. | from TraceableEventDispatcher | |
addSubscriber(EventSubscriberInterface $subscriber) Adds an event subscriber. | from TraceableEventDispatcher | |
removeListener(string $eventName, callable $listener) Removes an event listener from the specified events. | from TraceableEventDispatcher | |
removeSubscriber(EventSubscriberInterface $subscriber) Removes an event subscriber. | from TraceableEventDispatcher | |
array | getListeners(string $eventName = null) Gets the listeners of a specific event or all listeners sorted by descending priority. | from TraceableEventDispatcher |
int|null | getListenerPriority(string $eventName, callable $listener) Gets the listener priority for a specific event. | from TraceableEventDispatcher |
bool | hasListeners(string $eventName = null) Checks whether an event has any registered listeners. | from TraceableEventDispatcher |
Event | dispatch(string $eventName, Event $event = null) Dispatches an event to all registered listeners. | from TraceableEventDispatcher |
array | getCalledListeners() Gets the called listeners. | from TraceableEventDispatcher |
array | getNotCalledListeners() Gets the not called listeners. | from TraceableEventDispatcher |

Constructor.
EventDispatcherInterface | $dispatcher | An EventDispatcherInterface instance |
Stopwatch | $stopwatch | A Stopwatch instance |
LoggerInterface | $logger | A LoggerInterface instance |
Adds an event listener that listens on the specified events.
string | $eventName | The event to listen on |
callable | $listener | The listener |
int | $priority | The higher this value, the earlier an event listener will be triggered in the chain (defaults to 0) |
Adds an event subscriber.
The subscriber is asked for all the events he is interested in and added as a listener for these events.
EventSubscriberInterface | $subscriber | The subscriber. |
Removes an event listener from the specified events.
string | $eventName | The event to remove a listener from |
callable | $listener | The listener to remove |
Removes an event subscriber.
EventSubscriberInterface | $subscriber | The subscriber |
Gets the listeners of a specific event or all listeners sorted by descending priority.
string | $eventName | The name of the event |
array | The event listeners for the specified event, or all event listeners by event name |
Gets the listener priority for a specific event.
Returns null if the event or the listener does not exist.
string | $eventName | The name of the event |
callable | $listener | The listener |
int|null | The event listener priority |
Checks whether an event has any registered listeners.
string | $eventName | The name of the event |
bool | true if the specified event has any listeners, false otherwise |
Dispatches an event to all registered listeners.
string | $eventName | The name of the event to dispatch. The name of the event is the name of the method that is invoked on listeners. |
Event | $event | The event to pass to the event handlers/listeners. If not supplied, an empty Event instance is created. |
Event |
Gets the called listeners.
array | An array of called listeners |
Gets the not called listeners.
array | An array of not called listeners |
Proxies all method calls to the original event dispatcher.
