      • bytesToInt

        public static int bytesToInt​(byte[] array,
                             int offset)
        Unmarshal a byte array to an integer. Assume the bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+3] is the least-significant-byte.
        Parameters:
        array - The array of bytes.
        offset - The offset from which to start unmarshalling.

      • intToBytes

        public static byte[] intToBytes​(int value)
        Marshal an integer to a byte array. The bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+3] is the least-significant-byte.

      • intToBytes

        public static void intToBytes​(int value,
                              byte[] array,
                              int offset)

      • longToBytes

        public static byte[] longToBytes​(long value)
        Unmarshal a byte array to an long. Assume the bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+7] is the least-significant-byte.

      • bytesToLong

        public static long bytesToLong​(byte[] array,
                               int offset)

      • longToBytes

        public static void longToBytes​(long value,
                               byte[] array,
                               int offset)
        Marshal an long to a byte array. The bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+7] is the least-significant-byte.
        Parameters:
        array - The array of bytes.
        offset - The offset from which to start marshalling.
