 * The core class for wrapping classes as annotated classes. The annotated class provides access to all declared and inherited annotations from
 * classes and interfaces. Also the annotated class provides wrapping for its methods for gathering all declared and inherited annotations for it from
 * base classes and interfaces.
 * <p>
 * By now only public methods can inherit annotations with the mechanism. (Comment: [RR] reworked that, now it fetches all methods, but sure it's a
 * workaround. (See: {@link com.aionemu.gameserver.utils.annotations.AnnotatedClassImpl#getAllMethods(Class, List)}
