public class CATBaseDispatch
Base class for Automation interfaces.
Role: All Automation interfaces must inherit from
the CATBaseDispatch interface. They usually do not
inherit directly from CATBaseDispatch, but rather
from one of its subclasses: CATIABase individual objects
or CATIACollection for collection objects.
Some methods may however have arguments of type CATBaseDispatch
when they accept both individual objects or collection objects.
The interface provides no functionalities per se.
