+/**
+ * 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 path. The annotation also
+ * recognizes several parameters: requirements, options, defaults, schemes,
+ * methods, host, 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()
+ *         {
+ *         }
+ *     }
