Interface RouteEntry

All Known Implementing Classes:

AbstractRouteEntry, AddPathAbstractRouteEntry

public interface RouteEntry

A single route entry inside a route table. Maintains the attributes of from all contributing peers. The information is stored in arrays with a shared map of offsets for peers to allow lookups. This is needed to maintain low memory overhead in face of large number of routes and peers, where individual object overhead becomes the dominating factor.
