org.castor.cache.hashbelt.reaper

Class ReinsertingReaper

Implemented Interfaces:
Reaper

public abstract class ReinsertingReaper
extends AbstractReaper

A hybrid of the notifying and refreshing reaper; like the notifying reaper, this calls handleExpiredObject for the object; like the refreshing reaper, it then reinserts it in the front of the expiration system. Unlike the refreshing reaper, it always returns the exact same object to the front of the expiration system.

Useful for alerts and announcements. E.g. suppose you're supposed to send someone an update every 15 minutes. Use this one and an object that sends the message inside its "expire" method.
