public class RTLookup

extends Contract

The RouteLookup contract. This contract defines the following service at the reactor:

RouteLookup

The initiator sends a key (RTKey) and the reactor returns the outgoing interfaces (int[]) of the entry, the key of which has the longest match to the given key.

This class also provides a static method (lookup(RTKey, Port)) to facilitate conducting the above service from the specified port. The method is particularly useful in implementing a protocol that needs to look up the routing entry.
