Customize Class Library

The following are the points to remember, while customizing the Class Library:

• The System Classes pre-defined as subclasses cannot be deleted.

• The upper levels of the class hierarchy are system pre-defined, and cannot be changed.

  • Any new class you create becomes a subclass of these system pre-defined classes.

• If any class is used as an Essential or Incidental classification of any object, that class cannot be deleted.

  • To delete that class, you must first delete the objects under that class.
