InterfaceDef Object

See Also

The properties, methods, and collections that a class implements are organized into functionally related groups. Each group is implemented as a repository interface. The properties, methods, and collections of each interface are members of the interface. An interface definition is the template to which an interface conforms.

To add a new interface to the Microsoft® Repository, use the ClassDef object or the ReposTypeLib object.

An InterfaceDef object is also a RepositoryObject object. In addition to the members described here, InterfaceDef objects also provide the members that are defined for repository objects.
