Class SimpleCachingHive

java.lang.Object

org.wicketstuff.security.hive.BasicHive

org.wicketstuff.security.hive.SimpleCachingHive

All Implemented Interfaces:

Hive

public class SimpleCachingHive
extends BasicHive

A very simple caching mechanism on top of BasicHive. If you want more control over your cache you could for example use EHCache and extend BasicHive yourself. This cache is cleared when a subject logs off but no guarantees are given that the cache will not be cleared prematurely or how long it takes after a user logs off to clear the cached results.
