IProvideMultipleClassInfo interface

An extension to IProvideClassInfo2 that makes it faster and easier to retrieve type information from a component that may have multiple coclasses that determine its behavior.

When to implement

Implement IProvideMultipleClassInfo on an object that aggregates from another. The component that aggregates is responsible for returning type information that will describe both components. By implementing this interface and publishing the way that the type information blocks are ordered, a component can provide both type information blocks.

When to use

Clients call the methods of the IProvideMultipleClassInfo interface to specify the kinds of information they are looking for. This allows more than one kind of information to be returned with a single call.
