  • Method Details

    • getHeader

    • getDataFieldLength

      public abstract int getDataFieldLength()

    • getCFDPPacket

      public static CfdpPacket getCFDPPacket(ByteBuffer bb) throws PduDecodingException
      Reads a CFDP PDU from the ByteBuffer at the current position.

      The buffer can contain more data than one PDU, at the end of the call the position will be set to the end of the PDU.

      In case of error (e.g. cannot decode header) a PduDecodingException is thrown and the position is undetermined.

      The return may be null if the PDU is not supported

      Throws:
      PduDecodingException
