    • Method Detail

      • toLong

        public static long toLong​(byte[] bytes)
        Converts a byte array to a long value. Reverses toBytes(long)

      • toLong

        public static long toLong​(byte[] bytes,
                          int offset)
        Converts a byte array to a long value. Assumes there will be SIZEOF_LONG bytes available.

      • toBytes

        public static byte[] toBytes​(long val)
        Convert a long value to a byte array using big-endian.

      • toBytes

        public static byte[] toBytes​(java.lang.String str)
        Converts a string to a UTF-8 byte array.

      • toCachedBytes

        public static byte[] toCachedBytes​(java.lang.String str)
        Converts a string to a UTF-8 byte array. This method will cache results and return cached results, so the resulting byte arrays must not be modified.
