Buffered Event Dispatcher
The buffered event dispatcher allows you to stage your events before
committing to publishing them. The buffered event dispatcher decorates
a Psr\EventDispatching\EventDisparcherInterface instance.
use League\Event\BufferedEventDispatcher;
use League\Event\EventDispatcher;
$internalDispatcher = new EventDispatcher();
$internalDispatcher->subscribeTo(stdClass::class, fn () => echo "Hello!");
$dispatcher = new BufferedEventDispatcher($internalDispatcher);
$dispatcher->dispatch(new stdClass()); // no listener is called;
$dispatcher->dispatch(new stdClass()); // no listener is called;
$dispatcher->dispatchBufferedEvents(); // listener is called twice
