Static version of EventManager

Allows attaching to EMs composed by other classes without having an instance first. The assumption is that the SharedEventManager will be injected into EventManager instances, and then queried for additional listeners when triggering an event.

Allows attaching a callback to an event offerred by one or more identifying components. As an example, the following connects to the "getAll" event of both an AbstractResource and EntityResource:

SharedEventManager::getInstance()->connect( array('My\Resource\AbstractResource', 'My\Resource\EntityResource'), 'getOne', function ($e) use ($cache) { if (!$id = $e->getParam('id', false)) { return; } if (!$data = $cache->load(get_class($resource) . '::getOne::' . $id )) { return; } return $data; } );
