      • nextUID

        public static java.lang.String nextUID()
        Returns a string that can be used as part of a Java identifier and is unique for this JVM. Currently returns a hexadecimal string and initialized by System.nanoTime() (but both those details may change in the future). Note that the returned value may start with a numeric digit, so it should be used as a suffix, not prefix of a Java identifier.
