Detailed Description

template<class A>
class RouteRange< A >

Stores a Route and bounds on the validity of the route.

The RouteRange class is used to hold an annotated routing entry. It is used when the RegisterTable is registering interest in routing information associated with a specific address. It holds an IP address, the route that would be used to route that address, and the top and bottom addresses of the route range that includes that address for which this route applies without being overlayed by a more specific route. For example:

Suppose an OriginTable holds the routes 1.0.0.0/16 and 1.0.1.0/24. The address we're interested in is 1.0.0.10. Then if we ask this OriginTable for the RouteRange for 1.0.0.10, we get:

address: 1.0.0.10 route: the route for 1.0.0.0/16 top: 1.0.0.255 bottom: 1.0.0.0

I.e., the route for 1.0.0.10 is 1.0.0.0/16, and this answer is also valid for addresses in the range 1.0.0.0 to 1.0.0.255 inclusive.
