Class Overview

The Relation Service is in charge of creating and deleting relation types and relations, of handling the consistency and of providing query mechanisms.

It implements the NotificationBroadcaster by extending NotificationBroadcasterSupport to send notifications when a relation is removed from it.

It implements the NotificationListener interface to be able to receive notifications concerning unregistration of MBeans referenced in relation roles and of relation MBeans.

It implements the MBeanRegistration interface to be able to retrieve its ObjectName and MBean Server.

public void postDeregister ()

Allows the MBean to perform any operations needed after having been unregistered in the MBean server.

public void postRegister (Boolean registrationDone)

Allows the MBean to perform any operations needed after having been registered in the MBean server or after the registration has failed.

Parameters
registrationDone Indicates whether or not the MBean has been successfully registered in the MBean server. The value false means that the registration phase has failed.

public void preDeregister ()

Allows the MBean to perform any operations it needs before being unregistered by the MBean server.

Throws
Exception

public ObjectName preRegister (MBeanServer server, ObjectName name)

Allows the MBean to perform any operations it needs before being registered in the MBean server. If the name of the MBean is not specified, the MBean can provide a name for its registration. If any exception is raised, the MBean will not be registered in the MBean server.

Parameters
server The MBean server in which the MBean will be registered.
name The object name of the MBean. This name is null if the name parameter to one of the createMBean or registerMBean methods in the MBeanServer interface is null. In that case, this method must return a non-null ObjectName for the new MBean.
Returns
  • The name under which the MBean is to be registered. This value must not be null. If the name parameter is not null, it will usually but not necessarily be the returned value.
Throws
Exception

public void purgeRelations ()

Purges the relations.

Depending on the purgeFlag value, this method is either called automatically when a notification is received for the unregistration of an MBean referenced in a relation (if the flag is set to true), or not (if the flag is set to false).

In that case it is up to the user to call it to maintain the consistency of the relations. To be kept in mind that if an MBean is unregistered and the purge not done immediately, if the ObjectName is reused and assigned to another MBean referenced in a relation, calling manually this purgeRelations() method will cause trouble, as will consider the ObjectName as corresponding to the unregistered MBean, not seeing the new one.

The behavior depends on the cardinality of the role where the unregistered MBean is referenced:

- if removing one MBean reference in the role makes its number of references less than the minimum degree, the relation has to be removed.

- if the remaining number of references after removing the MBean reference is still in the cardinality range, keep the relation and update it calling its handleMBeanUnregistration() callback.

Throws
RelationServiceNotRegisteredException if the Relation Service is not registered in the MBean Server.

public void removeRelation (String relationId)

A RelationNotification notification is sent, its type being:

- RelationNotification.RELATION_BASIC_REMOVAL if the relation was only internal to the Relation Service

For MBeans referenced in such relation, nothing will be done,

RelationServiceNotRegisteredException if the Relation Service is not registered in the MBean Server
IllegalArgumentException if null parameter
RelationNotFoundException if no relation corresponding to given relation id

The relation objects of that type will be removed from the Relation Service.

Parameters

RelationTypeNotFoundException If there is no relation type with that name

public void sendRelationCreationNotification (String relationId)
