        public static void scramble()
        Shuffle the mapping strings in random order, thus making the generator produce a different mapping. Can be called once (and only once) in each obfuscation run; calling this method repeatedly would produce overlapping names.

        public java.lang.String nextName​(java.lang.String descriptor)
        Return the next unique name for this namespace.
        Specified by:
