org.jboss.system.pm
Class AttributePersistenceService

java.lang.Object
  org.jboss.mx.util.JBossNotificationBroadcasterSupport
      org.jboss.system.ServiceMBeanSupport
          org.jboss.system.pm.AttributePersistenceService

All Implemented Interfaces:: AttributePersistenceServiceMBean, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, Service, ServiceMBean

public class AttributePersistenceService
extends ServiceMBeanSupport
implements AttributePersistenceServiceMBean

AttributePersistenceService Works in conjuction with org.jboss.mx.persistence.DelegatingPersistenceManager that upon creation, consults this service for an implementations of the interface org.jboss.mx.persistence.AttributePersistenceManager The service will instantiate and initialize the actual persistence manager and return it whenever asked. It also introduces the notion of a 'version', when creating the persistent manager, so that persisted data from different versions are kept separately. The service can be stopped, the version can be changed and the service re-started, resulting in a new persistent manager being instantiated and all XMBeans created thereafter using this instead. So the goal is really to have a way to plug-in external and manageable persistent managers that that support versioning, too.
