public class DynamicRouteApp

extends Application

implements NeighborListener

The "app" that maintains a node's dynamic routing tables.

This is really just an app so it can justify sending capsules off without priming them off some other capsule. (All this code used to be part of DynamicRouteTable.)

Understands the default '-port' argument that all apps grok.

Constructor Detail

DynamicRouteApp

public DynamicRouteApp()

App constructors can't do anything useful. Ideally, I would like to set this.node and this.table, but I can't because the node hasn't been plugged into this app yet, and I need to node to get the table...

Method Detail

setArgs

public void setArgs(KeyArgs k)
             throws InvalidKeyArgsException

Parse command line arguments.

See the class description for a list of the arguments and their meaning.

Overrides:

setArgs in class Application

Tags copied from class: Application

#port, KeyArgs

start

public void start()

The active route table logic.

Harmless if invoked on a static table.

Overrides:

start in class Application

receive

public void receive(Capsule unknownCap)

Receive and process RouteUpdateCapsule. RouteUpdateCapsules contain zero or more route update records. Each "record" consists of a destination and a "distance" to that destination.

Overrides:

receive in class Application

Parameters:

unknownCap - the RouteUpdateCapsule.

neighborAdded

public void neighborAdded(int address,
                          edu.utah.janos.nodeos.Address link)

A neighbor was added to the neighbor table

Specified by:

neighborAdded in interface NeighborListener

neighborRemoved

public void neighborRemoved(int address,
                            edu.utah.janos.nodeos.Address link)

A neighbor was removed from the neighbor table

Specified by:

neighborRemoved in interface NeighborListener
