Internally, Symfony converts short controller names (FooBundle:Home:index) to a controller/action pair that PHP understands. In #7843, Bart van den Burg, added a way to do the reverse: transform a controller::action string to its short name notation ($container->get(‘controller_name_converter’)->build(‘Symfony\Bundle\FrameworkBundle\Controller\RedirectController::redirectAction’); would return FrameworkBundle:Redirect:redirect).
