Detailed Description

The Update Queue has is conceptually a single writer multi-reader queue. It is used to store state for triggered updates and may be used unsolicited responses (routing table announcements).

Add update to back of queue.

Remove all queued entries and reset all read iterators to the front of the queue.

Create a read iterator. These are reference counted entities that need to be stored in order to operate.

Destroy read iterator. This method detaches the iterator from the update queue. Use of the iterator after this call is unsafe.

[const]

Increment iterator and return pointer to entry if available.

Returns: RouteEntry if available, 0 otherwise.

[const]

Get the RouteEntry associated with the read iterator.
