  • Method Details

    • decode

      long decode(byte[] buf, int offset)
      Decodes the time from the binary buffer and returns the time in milliseconds. The value returned can be either absolute or relative (this has to be known by the caller)

      It is assumed that the buffer will contain enough data; if not, an ArrayIndexOutOfBoundsException will be thrown.

      Parameters:
      buf - - where to read the data from
      offset - - offset in the buffer where the decoding will begin
      Returns:
      decoded time in milliseconds

    • decodeRaw

      long decodeRaw(byte[] buf, int offset)
      Returns the time in an unspecified unit.

      Can be used when the on-board time is free running.

      It is assumed that the buffer will contain enough data; if not, an ArrayIndexOutOfBoundsException will be thrown.

      Parameters:
      buf - - where to read the data from
      offset - - offset in the buffer where the decoding will begin
      Returns:
      time
