A NotfiyQueue holds a queue of route event notifications waiting transmission to the XORP process that registered interest in route changes that affected one or more routes. When a lot of routes change, we need to queue the changes because we may generate them faster than the recipient can handle being told about them.
| NotifyQueue (const string& module_name)
|module_name||the XRL module target name for the process that this queue holds notifications for.|
|void add_entry (NotifyQueueEntry* e)
Add an notification entry to the queue.
|e||the notification entry to be queued.|
|void send_next ()
Send the next entry in the queue to this queue's XRL target.
|void flush (ResponseSender* response_sender)
Flush is an indication to the queue that the changes since the last flush can be checked for consolidation. Several add_entry events might occur in rapid succession affecting the same route. A flush indicates that it is OK to start sending this batch of changes (and to consolidate those changes to avoid thrashing, but we don't currently do this).
|void xrl_done (const XrlError& e)
XRL transmit complete callback. We use this to cause the next item in the queue to be sent.
|e||the XRL completion status code.|
|typedef XorpCallback1<void, const XrlError&>::RefPtr XrlCompleteCB|
