Class CacheEvent

java.lang.Object

java.util.EventObject

stella.io.CacheEvent

All Implemented Interfaces:

Serializable

public class CacheEvent
extends EventObject

An event signaling that the value mapped to a specific key in a polling server's cache has changed. Registered listeners get an event of this type passed to their CacheChangedListener.newValue(stella.io.CacheChangedEvent) method. Note that this event also carries the value of the key to allow the listener to judge whether the event was received accidently.

This event is a purely internal one. No rmi-transport is ever intended. Therefore, all definitions are found in this package, and this event class only extends the generic EventObject class rather than the {stella.rmi.RmiEvent} class. Additionally, the appropriate caster interface does not implement the generic Caster interface.
