    • Method Detail

      • fromTransmission

        public void fromTransmission​(Sequence aSequence,
                             int aOffset,
                             int aLength)
                      throws TransmissionException
        (Re-)initializes this instance with the the given Sequence data. This method merely delegates to the decoratee and does not do any packaging as we do not have a stream which we can packetize, we have a Sequence provided.
        Specified by:
        fromTransmission in interface Section
        Parameters:
        aSequence - The Sequence data from which to (re-)initialize this instance.
        aOffset - The offset where to start processing the provided Sequence.
        aLength - The length of data assigned by the Sequence.
        Throws:
        TransmissionException - thrown in case a given Sequence cannot be processed.

      • receiveFrom

        public void receiveFrom​(InputStream aInputStream,
                        int aLength,
                        OutputStream aReturnStream)
                 throws IOException,
                        TransmissionException
        (Re-)initializes this instance by receiving the according Sequence from the given InputStream. Implementations providing error correction methods use the provided feedback OutputStream to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the received data.
        Specified by:
        receiveFrom in interface Section
        Parameters:
        aInputStream - The InputStream from which to read the instance's (re-)initialization Sequence from.
        aLength - The length of data assigned by the byte array.
        aReturnStream - An OutputStream being the return channel to handle "stop-and-wait ARQ" or the like in case of a bidirectional connection. Can be null in case we have a unidirectional connection.
        Throws:
        IOException - thrown in case reading data from the InputStream caused problems.
        TransmissionException - thrown in case a given InputStream bytes cannot be processed.
