Examples of net.sf.ehcache.event.RegisteredEventListeners

net.sf.ehcache.event.RegisteredEventListeners
Registered listeners for registering and unregistering CacheEventListeners and multicasting notifications to registrants.
There is one of these per Cache.
This class also has counters to accumulate the numbers of each type of event for statistics purposes. @author Greg Luck @version $Id: RegisteredEventListeners.java 744 2008-08-16 20:10:49Z gregluck $
