    It is called in relation MBean setRole() (for given role) and setRoles() (for each role) methods (implementation provided in RelationSupport class).
    It is also called in Relation Service setRole() (for given role) and setRoles() (for each role) methods.

    newRole - new role (name and new value)
    oldRoleValue - old role value (List of ObjectName objects)

  - removeRelation

void removeRelation(String relationId)

                           IllegalArgumentException,
                           RelationNotFoundException
```
    Removes given relation from the Relation Service.
    A RelationNotification notification is sent, its type being:
    - RelationNotification.RELATION_BASIC_REMOVAL if the relation was only internal to the Relation Service
    - RelationNotification.RELATION_MBEAN_REMOVAL if the relation is registered as an MBean.
    For MBeans referenced in such relation, nothing will be done,
    
    Parameters:
    relationId - relation id of the relation to be removed
    
    Throws:
    
    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
  - purgeRelations
```
void purgeRelations()
                    throws RelationServiceNotRegisteredException
```
    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.

    Retrieves the relations where a given MBean is referenced.
    This corresponds to the CIM "References" and "ReferenceNames" operations.
    
    Parameters:
    mbeanName - ObjectName of MBean
    relationTypeName - can be null; if specified, only the relations of that type will be considered in the search. Else all relation types are considered.
    roleName - can be null; if specified, only the relations where the MBean is referenced in that role will be returned. Else all roles are considered.
    
    Returns:
    an HashMap, where the keys are the relation ids of the relations where the MBean is referenced, and the value is, for each key, an ArrayList of role names (as an MBean can be referenced in several roles in the same relation).
