/**
 *  This interface is a marker interface to identify generated Proxy classes.
 *
 *  It has no special methods and is only used, so that at runtime a user might evaluate, if any specific class
 *  is a generated proxy or not. If any class is instance of this interface, it is by contract a generated class.
 *  Especially the default annotation processor automatically applies this interface.
 *
 *  For convenience the method {@link #isProxy(Object)} may be used, to check if any specific object is a proxy. Just
 *  note that you should normally never require this check. If you find yourself requiring this method, consider
 *  overthinking the approach you are currently implementing.
