ClassDef Object
The ClassDef object helps you create information models by adding interfaces to a class. To insert a new class definition into an information model, use the ReposTypeLib object.
Once you have added all of the interfaces, you complete a class definition by committing the transaction that brackets your class definition modifications.
A ClassDef object is also a RepositoryObject and a RepositoryObjectVersion object. You can also access members that are defined for those objects and members of IViewClassDef and IVersionAdminInfo. For more information about accessing a member of an interface that is not the default interface, see Accessing Automation Object Members.
When to Use
Use the ClassDef object to:
- Add a new or existing interface to a class definition.
- Retrieve the global identifier for the class.
- Access the collection of interfaces that are part of a class definition.
