public static function EventArgs::getEmptyInstance in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 vendor/doctrine/common/lib/Doctrine/Common/EventArgs.php \Doctrine\Common\EventArgs::getEmptyInstance()

Gets the single, empty and immutable EventArgs instance.

This instance will be used when events are dispatched without any parameter, like this: EventManager::dispatchEvent('eventname');

The benefit from this is that only one empty instance is instantiated and shared (otherwise there would be instances for every dispatched in the abovementioned form).
