The notification type is:

object internal to the Relation Service

The source object is the Relation Service itself.

It is called in Relation Service removeRelation() method.

To allow the Relation Service to maintain the consistency (in case

A RelationNotification notification is sent, its type being:

only internal to the Relation Service

- RelationNotification.RELATION_MBEAN_REMOVAL if the relation is

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.
