Examples of org.jgroups.stack.NakReceiverWindow$Listener

org.jgroups.stack.NakReceiverWindow
Keeps track of messages according to their sequence numbers. Allows messages to be added out of order, and with gaps between sequence numbers. Method remove() removes the first message with a sequence number that is 1 higher than next_to_remove (this variable is then incremented), or it returns null if no message is present, or if no message's sequence number is 1 higher.
When there is a gap upon adding a message, its seqno will be added to the Retransmitter, which (using a timer) requests retransmissions of missing messages and keeps on trying until the message has been received, or the member who sent the message is suspected. There are 3 variables which keep track of messages:
- low: lowest seqno, modified on stable(). On stable(), we purge msgs [low digest.highest_delivered]
- highest_delivered: the highest delivered seqno, updated on remove(). The next message to be removed is highest_delivered + 1
- highest_received: the highest received message, updated on add (if a new message is added, not updated e.g. if a missing msg was received)
Note that the first seqno expected is 1. This design is described in doc/design.NAKACK.txt
Example: 1,2,3,5,6,8: low=1, highest_delivered=2 (or 3, depending on whether remove() was called !), highest_received=8 @author Bela Ban
