  • Method Details

    • decode

      public long decode(byte[] buf, int offset)
      Description copied from interface: TimeDecoder
      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.

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

    • decodeRaw

      public long decodeRaw(byte[] buf, int offset)
      Description copied from interface: TimeDecoder
      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.

      Specified by:
      decodeRaw in interface TimeDecoder
      Parameters:
      buf - - where to read the data from
      offset - - offset in the buffer where the decoding will begin
      Returns:
      time
