Examples of Ehcache

net.sf.ehcache.Ehcache
An interface for Ehcache.
Ehcache is the central interface. Caches have {@link Element}s and are managed by the {@link CacheManager}. The Cache performs logical actions. It delegates physical implementations to its {@link net.sf.ehcache.store.Store}s.
A reference to an EhCache can be obtained through the {@link CacheManager}. An Ehcache thus obtained is guaranteed to have status {@link Status#STATUS_ALIVE}. This status is checked for any method which throws {@link IllegalStateException} and the same thrown if it is not alive. This would normallyhappen if a call is made after {@link CacheManager#shutdown} is invoked.
Statistics on cache usage are collected and made available through public methods. @author Greg Luck @version $Id: Ehcache.java 796 2008-10-09 02:39:03Z gregluck $
