org.nasutekds.server.admin.RelationDefinition
Relation definitions define relationships between types of managed objects. In addition they define the ownership model:
- composition - referenced managed objects are owned by the parent managed object and are deleted when the parent is deleted
- aggregation - referenced managed objects are not owned by the parent managed object. Instead they are shared by other managed objects.
Relations define how clients interact with the configuration. For example, clients manage aggregated managed objects in a shared location and attach them to parent managed objects. Composed managed objects, on the other hand, would be created directly beneath the parent managed object and destroyed with it too.
Within the server, listeners can choose to request notification of managed objects being added or removed from relations.
In LDAP, compositions are represented as follows:
- singleton relations (one to one): a referenced managed object is represented using a child entry directly beneath the parent
- optional relations (one to zero or one): a referenced managed object is represented using a child entry directly beneath the parent
- instantiable relations (one to many): the relation is represented using a child entry directly beneath the parent. Referenced managed objects are represented using child entries of this "relation entry" and are named by the user
- set relations (one to many): the relation is represented using a child entry directly beneath the parent. Referenced managed objects are represented using child entries of this "relation entry" whose name is the type of the managed object.
Whereas, aggregations are represented by storing the DNs of the referenced managed objects in an attribute of the aggregating managed object. @param < C> The type of client managed object configuration that this relation definition refers to. @param < S> The type of server managed object configuration that this relation definition refers to.
