Package org.jboss.as.ejb3.component.stateful.cache.simple

Class SimpleStatefulSessionBeanCache<K,V extends StatefulSessionBeanInstance<K>>

java.lang.Object

org.jboss.as.ejb3.component.stateful.cache.simple.SimpleStatefulSessionBeanCache<K,V>

Type Parameters:

K - the bean identifier type

V - the bean instance type

All Implemented Interfaces:

Consumer<StatefulSessionBean<K,V>>, Predicate<K>, StatefulSessionBeanCache<K,V>, BeanStatistics, AffinitySupport<K>, org.wildfly.clustering.server.manager.Service

public class SimpleStatefulSessionBeanCache<K,V extends StatefulSessionBeanInstance<K>>
extends Object
implements StatefulSessionBeanCache<K,V>, Predicate<K>, Consumer<StatefulSessionBean<K,V>>

A simple stateful session bean cache implementation. Bean instances are stored in memory and are lost on undeploy, shutdown, or server crash.
