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 (const string& module_name)

NotifyQueue

NotifyQueue constructor

Parameters:

module_name

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

void add_entry (NotifyQueueEntry* e)

add_entry

Add an notification entry to the queue.

Parameters:

e	the notification entry to be queued.

void send_next ()

send_next

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

void flush (ResponseSender* response_sender)

flush

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_done

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.

typedef XorpCallback1<void, const XrlError&>::RefPtr XrlCompleteCB
