Detailed Description

The RouteDB class holds routes and manages their updates. Successful updates are placed in the update queue contained within the RouteDB instance. The UpdateQueue is used for generating triggered update messages.

The RouteWalker class provides a way to walk the routes held.

Update Route Entry in database for specified route.

If the route does not exist or the values provided differ from the existing route, then an update is placed in the update queue.

Parameters:

net	the network route being updated.
nexthop	the corresponding nexthop address.
cost	the corresponding metric value as received from the route originator.
tag	the corresponding route tag.
origin	the route originator proposing update.

Returns: true if an update occurs, false otherwise.

Flatten route entry collection into a Vector.

Parameters:

routes

vector where routes are to be appended.

Flush routes.

[const]

Returns: count of routes in database.

[const]

Returns: pointer to route entry if it exists, 0 otherwise.

Accessor.

Returns: reference to UpdateQueue.

[const]

Accessor.

Returns: const reference to UpdateQueue.
