   static final int EMPTY

An EMPTY event. DynamicRouteEvents are never initialized with this value. They just decay to it after they expire.

   static final int PERIODIC

The PERODIC event. These trigger periodically (duh) and send a full update to all neighbor gateways.

   static final int TRIGGER

The TRIGGER event. Trigger events are scheduled for a short time in the future to propagate recent changes.

   static final int GC

The GC event is triggered on a route when it is time for the route to be retired. Routes are first moved into a gc pool where they can be ressurected. Otherwise they will EXPIRE.

   static final int EXPIRE

The EXPIRE event. This event is triggered on a route after its been placed in the GC pool and if it doesn't get resurrected. EXPIRED routes are deleted.

   final long when

Timestamp of when this event is scheduled to be invoked.

   int what

A set of flags indicating what sort of events this object implies (Periodic, trigger, expire, or GC).

This is mutable. Events may be added if they occur at the same time as a different event.

   int expireCount

Let me know if you figure out what this does.

   int gcCount

Let me know if you figure out what this does.
