The ActionScript reference for rich Internet application development provides an alphabetical reference for all native ActionScript APIs for the Adobe technology platform runtimes: Adobe Flash Player and Adobe AIRâ€”as well as the Adobe Flex framework APIs. Use this guide both as an API reference and a tool to learn about the ActionScript APIs available within the runtimes.

The Adobe technology platform contains two primary runtimes. Flash Player is browser-based, and Adobe AIR is desktop-based. Because Adobe AIR is built on top of Flash Player, the Flash Player APIs are available within Adobe AIR. Consequently, Adobe AIR APIs are not available within Flash Player. The Flex framework is built on top of the Flash Player APIs, so it runs in both Flash Player and Adobe AIR. However, a number of Flex APIs take advantage of AIR APIs, and thus work only within Adobe AIR.
