      • bytes

        public static byte[] bytes​(java.lang.String str)
        Convert a String to a UTF-8 byte array.
        Parameters:
        str - the string
        Returns:
        the byte array.

      • memcmp

        public static int memcmp​(java.nio.ByteBuffer x,
                         java.nio.ByteBuffer y,
                         int count)
        Compares the first count bytes of two areas of memory. Returns zero if they are the same, a value less than zero if x is lexically less than y, or a value greater than zero if x is lexically greater than y. Note that lexical order is determined as if comparing unsigned char arrays. Similar to memcmp.c.
        Parameters:
        x - the first value to compare with
        y - the second value to compare against
        count - the number of bytes to compare
        Returns:
        the result of the comparison
