InterfaceDef Class
The properties, methods, and collections that a class implements are organized into functionally related groups. Each group is implemented as a COM 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. Interface definitions are instances of the InterfaceDef class.
To create a new interface definition, use the ClassDef class or the ReposTypeLib class.
When to Use
Use the InterfaceDef class to:
- Retrieve or modify properties of an interface definition.
- Determine which members are attached to an interface definition.
- Determine which classes implement an interface.
- Determine the base interface from which an interface derives.
- Determine what interfaces derive from a particular interface.
- Determine which repository objects expose a particular interface.
- Add a new property, method, or collection type to an interface definition.
