RelationNotification

public RelationNotification(String notifType,
 Object sourceObj,
 long sequence,
 long timeStamp,
 String message,
 String id,
 String typeName,
 ObjectName objectName,
 List<ObjectName> unregMBeanList)
                     throws IllegalArgumentException

Creates a notification for either a relation creation (RelationSupport object created internally in the Relation Service, or an MBean added as a relation) or for a relation removal from the Relation Service.

Parameters:

notifType - type of the notification; either:

- RELATION_BASIC_CREATION

- RELATION_MBEAN_CREATION

- RELATION_BASIC_REMOVAL

- RELATION_MBEAN_REMOVAL

sourceObj - source object, sending the notification. This is either an ObjectName or a RelationService object. In the latter case it must be the MBean emitting the notification; the MBean Server will rewrite the source to be the ObjectName under which that MBean is registered.

sequence - sequence number to identify the notification

timeStamp - time stamp

message - human-readable message describing the notification

id - relation id identifying the relation in the Relation Service

typeName - name of the relation type

objectName - ObjectName of the relation object if it is an MBean (null for relations internally handled by the Relation Service)

unregMBeanList - list of ObjectNames of referenced MBeans expected to be unregistered due to relation removal (only for removal, due to CIM qualifiers, can be null)

Throws:

IllegalArgumentException - if:

- no value for the notification type

- the notification type is not RELATION_BASIC_CREATION, RELATION_MBEAN_CREATION, RELATION_BASIC_REMOVAL or RELATION_MBEAN_REMOVAL

- no source object

- the source object is not a Relation Service

- no relation id

- no relation type name

 String typeName,
 ObjectName objectName,
 String name,
 List<ObjectName> newValue,
 List<ObjectName> oldValue)
                     throws IllegalArgumentException

Creates a notification for a role update in a relation.

Parameters:

notifType - type of the notification; either:

- RELATION_BASIC_UPDATE

- RELATION_MBEAN_UPDATE

sourceObj - source object, sending the notification. This is either an ObjectName or a RelationService object. In the latter case it must be the MBean emitting the notification; the MBean Server will rewrite the source to be the ObjectName under which that MBean is registered.

sequence - sequence number to identify the notification

timeStamp - time stamp

message - human-readable message describing the notification

id - relation id identifying the relation in the Relation Service

typeName - name of the relation type

objectName - ObjectName of the relation object if it is an MBean (null for relations internally handled by the Relation Service)

name - name of the updated role

newValue - new role value (List of ObjectName objects)

oldValue - old role value (List of ObjectName objects)

Throws:

IllegalArgumentException - if null parameter
