Elgg\HooksRegistrationService::hasHandler PHP Метод

public hasHandler ( string $name, string $type ) : boolean
$name	string	The name of the hook
$type	string	The type of the hook
Результат	boolean

    public function hasHandler($name, $type)
    {
        return !empty($this->registrations[$name][$type]);
    }
