About This Reference

The Addon Interfaces Library Reference is intended for users who want to use the library to create addons that dynamically add functionality to applications. You can use addons to add functionality to your application without requiring redeployment of the entire application.

The new Multimedia Library uses the Addon Interfaces Library to build its interfaces. For more information about the Multimedia Library, and to see examples of interfaces implemented with the Addon Interfaces Library, see the Multimedia Developer's Guide.
