IClassDef Interface
See Also
The IClassDef interface helps you create information models by adding interfaces to a class. To insert a new class definition into an information model, use the IReposTypeLib interface.
To complete a class definition, once you have added all of the interfaces, commit the transaction that brackets your class definition modifications.
When to Use
Use the IClassDef interface 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.
