    • Method Detail

      • convertBytesToHexString

        public static String convertBytesToHexString​(byte[] data)
        Converts an array of bytes in to a String of hexadecimal characters (0 - F).
        Parameters:
        data - An array of bytes to convert to a String.
        Returns:
        A hexadecimal String representation of the data.
      • convertHexStringToBytes

        public static byte[] convertHexStringToBytes​(String hex)
        Converts a hexadecimal String (such as one generated by the convertBytesToHexString(byte[]) method) into an array of bytes.
        Parameters:
        hex - The hexadecimal String to be converted into an array of bytes.
        Returns:
        An array of bytes that.
      • convertBytesToInt

        public static int convertBytesToInt​(byte[] bytes,
                                            int offset)
        Take four bytes from the specified position in the specified block and convert them into a 32-bit int, using the big-endian convention.
        Parameters:
        bytes - The data to read from.
        offset - The position to start reading the 4-byte int from.
        Returns:
        The 32-bit integer represented by the four bytes.
      • convertBytesToInts

        public static int[] convertBytesToInts​(byte[] bytes)
        Convert an array of bytes into an array of ints. 4 bytes from the input data map to a single int in the output data.
        Parameters:
        bytes - The data to read from.
        Returns:
        An array of 32-bit integers constructed from the data.
        Since:
        1.1
      • convertBytesToLong

        public static long convertBytesToLong​(byte[] bytes,
                                              int offset)
        Utility method to convert an array of bytes into a long. Byte ordered is assumed to be big-endian.
        Parameters:
        bytes - The data to read from.
        offset - The position to start reading the 8-byte long from.
        Returns:
        The 64-bit integer represented by the eight bytes.
        Since:
        1.1
      • convertDoubleToFixedPointBits

        public static BitString convertDoubleToFixedPointBits​(double value)
        Converts a floating point value in the range 0 - 1 into a fixed point bit string (where the most significant bit has a value of 0.5).
        Parameters:
        value - The value to convert (must be between zero and one).
        Returns:
        A bit string representing the value in fixed-point format.
