IClassActivator:IUnknown
This interface specifies a method that retrieves a class object.
When to Implement
No implementation of a moniker or an object supporting IClassActivator currently exists within the system, however future versions of the operating system can contain such implementations. Implement the IClassActivator interface if you are writing a custom moniker type that you want to be able to compose to the left of a class moniker or any other moniker that supports binding to IClassActivator.
When to Use
Use IClassActivator if you write a custom moniker class that should behave similarly to class monikers when composed to the right of other monikers. File monikers also use this interface.
