Member Function Documentation

virtual void 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 TCP_NSC_VirtualDataReceiveQueue.

virtual cPacket* 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 NULL if there's no more data to be passed up -- this method is called several times until it returns NULL.

called after socket->read_data() successfull

Implemented in TCP_NSC_VirtualDataReceiveQueue.

virtual uint32 TCP_NSC_ReceiveQueue::getAmountOfBufferedBytes ( ) [pure virtual]

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

Implemented in TCP_NSC_VirtualDataReceiveQueue.

virtual uint32 TCP_NSC_ReceiveQueue::getQueueLength ( ) [pure virtual]

Returns the number of blocks currently buffered in queue.

Implemented in TCP_NSC_VirtualDataReceiveQueue.

virtual void TCP_NSC_ReceiveQueue::getQueueStatus ( ) [pure virtual]

Shows current queue status.

Implemented in TCP_NSC_VirtualDataReceiveQueue.

virtual uint32 TCP_NSC_ReceiveQueue::insertBytesFromSegment	(	const TCPSegment *	tcpsegP,
		void *	bufferP,
		size_t	bufferLengthP
	)			`[pure virtual]`

Called when a TCP segment arrives, it should extract the payload from the segment and store it in the receive queue. The segment object should *not* be deleted.

The method should return the number of bytes to copied to buffer.

The method should fill the bufferP for data sending to NSC stack

called before nsc_stack->if_receive_packet() called

Implemented in TCP_NSC_VirtualDataReceiveQueue.

virtual void 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 TCP_NSC_VirtualDataReceiveQueue.

virtual void TCP_NSC_ReceiveQueue::setConnection ( TCP_NSC_Connection * connP ) [inline, virtual]

Add a connection queue.

Reimplemented in TCP_NSC_VirtualDataReceiveQueue.
