virtual void inet::tcp::TCP_NSC_ReceiveQueue::enqueueNscData ( void *  dataP, int  dataLengthP  )

pure virtual

The method called when data received from NSC The method should set status of the data in queue to received called after socket->read_data() successfull.

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

Referenced by inet::tcp::TCP_NSC::handleIpInputMessage().

virtual cPacket* inet::tcp::TCP_NSC_ReceiveQueue::extractBytesUpTo ( )

pure virtual

Should create a packet to be passed up to the app, up to (but NOT including) the given sequence no (usually rcv_nxt).

It should return nullptr if there's no more data to be passed up – this method is called several times until it returns nullptr.

called after socket->read_data() successfull

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

virtual uint32 inet::tcp::TCP_NSC_ReceiveQueue::getAmountOfBufferedBytes ( ) const

pure virtual

Returns the number of bytes (out-of-order-segments) currently buffered in queue.

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

virtual uint32 inet::tcp::TCP_NSC_ReceiveQueue::getQueueLength ( ) const

pure virtual

Returns the number of blocks currently buffered in queue.

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

virtual void inet::tcp::TCP_NSC_ReceiveQueue::getQueueStatus ( ) const

pure virtual

Shows current queue status.

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

virtual void inet::tcp::TCP_NSC_ReceiveQueue::notifyAboutIncomingSegmentProcessing ( TCPSegment *  tcpsegP )

pure virtual

Called when a TCP segment arrives.

The segment object should not be deleted.

For remove and store payload messages if need.

virtual void inet::tcp::TCP_NSC_ReceiveQueue::notifyAboutSending ( const TCPSegment *  tcpsegP )

pure virtual

notify the queue about output messages

called when connM send out a packet. for read AckNo, if have

Implemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.

virtual void inet::tcp::TCP_NSC_ReceiveQueue::setConnection ( TCP_NSC_Connection *  connP )

inlinevirtual

Add a connection queue.

Reimplemented in inet::tcp::TCP_NSC_ByteStreamReceiveQueue, and inet::tcp::TCP_NSC_VirtualDataReceiveQueue.
