Java Source Code / Java Documentation » EJB Server JBoss 4.2.1 » server » org.jboss.ejb.plugins   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.jboss.ejb.plugins.AbstractInterceptor       org.jboss.ejb.plugins.EntitySynchronizationInterceptor All known Subclasses:   org.jboss.ejb.plugins.EntityMultiInstanceSynchronizationInterceptor, EntitySynchronizationInterceptor public class EntitySynchronizationInterceptor extends AbstractInterceptor (Code) The role of this interceptor is to synchronize the state of the cache with the underlying storage. It does this with the ejbLoad and ejbStore semantics of the EJB specification. In the presence of a transaction this is triggered by transaction demarcation. It registers a callback with the underlying transaction monitor through the JTA interfaces. If there is no transaction the policy is to store state upon returning from invocation. The synchronization polices A,B,C of the specification are taken care of here.
