File:Simple COM aggregation diagram.svg
Summary
A simple conceptual diagram of COM aggregation. The outer object exports an interface of the inner object called IInner, and an interface of its own, called IOuter, but it doesn't export IPrivate. The little interfaces on the top right of the objects represent the IUnknown interfaces of the objects. Since calling IUnknown methods on any interface of the inner object returns either an interface of the outer object, or an interface whose IUnknown methods call the IUnknown methods of the outer object, the outer object is the only object that has access to the IUnknown interface of the inner object.
