    • 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.
