/**
 * AnnotationClassLoader loads routing information from a PHP class and its methods.
 *
 * You need to define an implementation for the getRouteDefaults() method. Most of the
 * time, this method should define some PHP callable to be called for the route
 * (a controller in MVC speak).
 *
 * The @Route annotation can be set on the class (for global parameters),
 * and on each method.
 *
 * The @Route annotation main value is the route pattern. The annotation also
 * recognizes three parameters: requirements, options, and name. The name parameter
 * is mandatory. Here is an example of how you should be able to use it:
 *
 *     /**
 *      * @Route("/Blog")
 *      * /
 *     class Blog
 *     {
 *         /**
 *          * @Route("/", name="blog_index")
 *          * /
 *         public function index()
 *         {
 *         }
 *
 *         /**
 *          * @Route("/{id}", name="blog_post", requirements = {"id" = "\d+"})
 *          * /
 *         public function show()
 *         {
 *         }
 *     }
