Creates a {@code RelationSupport} object.

This constructor has to be used when the RelationSupport object will be registered as a MBean by the user, or when creating a user relation MBean whose class extends RelationSupport.

Nothing is done at the Relation Service level, i.e. the {@code RelationSupport} object is not added to the {@code RelationService} and no checks are performed to see if the provided values are correct. The object is always created, EXCEPT if:

- any of the required parameters is {@code null}.

- the same name is used for two roles.

To be handled as a relation, the {@code RelationSupport} object has to be added to the Relation Service using the Relation Service method addRelation().

Parameters:

relationId - relation identifier, to identify the relation in the Relation Service.

Expected to be unique in the given Relation Service.


relationServiceName - ObjectName of the Relation Service where the relation will be registered.

This parameter is required as it is the Relation Service that is aware of the definition of the relation type of the given relation, so that will be able to check update operations (set).


relationTypeName - Name of relation type.

Expected to have been created in the given Relation Service.


list - list of roles (Role objects) to initialize the relation. Can be {@code null}.

Expected to conform to relation info in associated relation type.


Throws:

InvalidRoleValueException - if the same name is used for two roles.

IllegalArgumentException - if any of the required parameters (relation id, relation service ObjectName, or relation type name) is {@code null}.

exception: InvalidRoleValueException - if the same name is used for two roles.

exception: IllegalArgumentException - if any of the required parameters (relation id, relation service ObjectName, or relation type name) is {@code null}.

}

Creates a {@code RelationSupport} object.

This constructor has to be used when the user relation MBean implements the interfaces expected to be supported by a relation by delegating to a RelationSupport object.

This object needs to know the Relation Service expected to handle the relation. So it has to know the MBean Server where the Relation Service is registered.

According to a limitation, a relation MBean must be registered in the same MBean Server as the Relation Service expected to handle it. So the user relation MBean has to be created and registered, and then the wrapped RelationSupport object can be created within the identified MBean Server.

Nothing is done at the Relation Service level, i.e. the {@code RelationSupport} object is not added to the {@code RelationService} and no checks are performed to see if the provided values are correct. The object is always created, EXCEPT if:

- any of the required parameters is {@code null}.

- the same name is used for two roles.

To be handled as a relation, the {@code RelationSupport} object has to be added to the Relation Service using the Relation Service method addRelation().

Parameters:

relationId - relation identifier, to identify the relation in the Relation Service.

Expected to be unique in the given Relation Service.


relationServiceName - ObjectName of the Relation Service where the relation will be registered.

This parameter is required as it is the Relation Service that is aware of the definition of the relation type of the given relation, so that will be able to check update operations (set).


relationServiceMBeanServer - MBean Server where the wrapping MBean is or will be registered.

Expected to be the MBean Server where the Relation Service is or will be registered.


relationTypeName - Name of relation type.

Expected to have been created in the given Relation Service.


list - list of roles (Role objects) to initialize the relation. Can be {@code null}.

Expected to conform to relation info in associated relation type.


Throws:

InvalidRoleValueException - if the same name is used for two roles.

IllegalArgumentException - if any of the required parameters (relation id, relation service ObjectName, relation service MBeanServer, or relation type name) is {@code null}.

exception: InvalidRoleValueException - if the same name is used for two roles.

exception: IllegalArgumentException - if any of the required parameters (relation id, relation service ObjectName, relation service MBeanServer, or relation type name) is {@code null}.

Callback used by the Relation Service when a MBean referenced in a role is unregistered.

The Relation Service will call this method to let the relation take action to reflect the impact of such unregistration.

BEWARE. the user is not expected to call this method.

Current implementation is to set the role with its current value (list of ObjectNames of referenced MBeans) without the unregistered one.
