If I had the following code how would I get the calling method and the class in the provider:
class HelloServiceProvider implements ServiceProviderInterface {
    public function register(Application $app){
        $app['hello'] = $app->share(function () {
            // Get hello/indexAction
        });
    }
    public function boot(Application $app){}
}
class hello {
    public function addAction(){
        $app['hello']()
    }
}
$app->get('/hello', 'hello.controller:indexAction');
Is this even possible? Thanks
