DSOM Framework Reference
ObjectMgr Class
Description
The ObjectMgr class provides a uniform, universal abstraction for any sort of object
manager. Object Request Brokers, persistent storage managers, and OODBMSs are
examples of object managers.
This is an abstract base class, which defines the “core” interface for an object manager. It
provides basic methods that:
Create a new object of a certain class,
Return a (persistent) ID for an object,
Return a reference to an object associated with an ID,
Free an object (that is, release any local memory associated with the object without
necessarily destroying the object itself), or
Destroy an object.
Note: The ObjectMgr is an abstract class and should not be instantiated. Any subclass of
ObjectMgr must provide implementations for all ObjectMgr methods. In DSOM, the class
SOMDObjectMgr provides a DSOM-specific implementation.
