      Description copied from interface: SleService
      Called at the beginning. to initialize the service.

    • processSleStopInvocation

      protected void processSleStopInvocation(SleStopInvocation sleStopInvocation)

    • sendStatusReport

      public void sendStatusReport()

    • sendFrame

      public void sendFrame(CcsdsTime ert, Constants.FrameQuality frameQuality, int dataLinkContinuity, byte[] data, int dataOffset, int dataLength)
      Called by the FrameSource to send a new frame.
      Specified by:
      sendFrame in class RacfServiceProvider
      Parameters:
      ert -
      frameQuality -
      dataLinkContinuity - from CCSDS spec:
      • a value of ‘–1’ shall indicate that this is the first frame after the start of production;</li
      • a value of ‘0’ shall indicate that this frame is the direct successor to the last frame acquired from the space link by RAF production;</li
      • any non-zero positive value shall indicate that this frame is not the direct successor to the last frame acquired from the space link:</li
      • a non-zero positive value further indicates an estimate of the number of frames that were missed since the last frame acquired before this frame;
      • a value of ‘1’ may be used if no better estimate is available.
      data - frame data
      dataOffset - where in the data the buffer the frame starts
      dataLength - the length of the frame data

    • sendEof

      public void sendEof()
      Description copied from class: RacfServiceProvider
      Called by the FrameSource to signal the end of data (used for offline instances)
      Specified by:
      sendEof in class RacfServiceProvider

    • getState

      public State getState()
      Description copied from interface: SleService
      Returns the service state.

      Should be one of State.READY or State.ACTIVE
