Detailed Description

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 constructor

Parameters:

modname

the XRL module target name for the process that this queue holds notifications for.

Add an notification entry to the queue.

Parameters:

e	the notification entry to be queued.

Send the next entry in the queue to this queue's XRL target.

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).

XRL transmit complete callback. We use this to cause the next item in the queue to be sent.

Parameters:

e	the XRL completion status code.
