Directory Server Object Class Implementation

Object classes in the directory server do not require any custom logic, so they can be implemented as data structures that are populated from information contained in the schema configuration files, much in the same way as for attribute type definitions. All object class instances in the directory server are instances of the org.opends.server.types.ObjectClass class. Object class objects can be retrieved from the directory server schema using their OIDs or any of their human-readable names.

At the present time, the mechanism used to handle object classes varies from the LDAPv3 specification in that object classes are allowed to have at most one superior class, whereas the specification allows multiple superior classes in some cases.
