+The Traceable Event Dispatcher
+==============================
+
+The :class:`Symfony\\Component\\HttpKernel\\Debug\\TraceableEventDispatcher`
+is an event dispatcher that wraps any other event dispatcher and can then
+be used to determine which event listeners have been called by the dispatcher.
+Pass the event dispatcher to be wrapped and an instance of the
+:class:`Symfony\\Component\\Stopwatch\\Stopwatch` to its constructor::
+
+    use Symfony\Component\HttpKernel\Debug\TraceableEventDispatcher;
+    use Symfony\Component\Stopwatch\Stopwatch;
+
+    // the event dispatcher to debug
+    $eventDispatcher = ...;
+
+    $traceableEventDispatcher = new TraceableEventDispatcher($eventDispatcher, new Stopwatch());
+
+Now, the ``TraceableEventDispatcher`` can be used like any other event dispatcher
+to register event listeners and dispatch events::
+
+    // ...
+
+    // register an event listener
+    $eventListener = ...;
+    $priority = ...;
+    $traceableEventDispatcher->addListener('the-event-name', $eventListener, $priority);
+
+    // dispatch an event
+    $event = ...;
+    $traceableEventDispatcher->dispatch('the-event-name', $event);
+
+After your application has been processed, you can use the
+:method:`Symfony\\Component\\EventDispatcher\\Debug\\TraceableEventDispatcherInterface::getCalledListeners`
+method to retrieve an array of event listeners that have been called in your
+application. Similarly, the
+:method:`Symfony\\Component\\EventDispatcher\\Debug\\TraceableEventDispatcherInterface::getNotCalledListeners`
+method returns an array of event listeners that have not been called::
+
+    // ...
+
+    $calledListeners = $traceableEventDispatcher->getCalledListeners();
+    $notCalledListeners = $traceableEventDispatcher->getNotCalledListeners();
