Utility objects

There are several object types that store information used for performing Contenta tasks.

A NullObject represents an object that has been removed from the Contenta database using the reap_delete or DBClean utilities. They are displayed in historical views of the database as placeholders for deleted objects. They do not contain the contents of the object they represent.

The following table describes the unique features of Utility objects.
