This class provides * the ability to execute API methods and have the call return immediately, * without blocking the calling thread. This is necessary when accessing the * API in the UI thread, for instance. The request response is returned to * the caller via a callback interface, which the developer must implement. * * This sample implementation simply spawns a new thread for each request, * and makes the API call immediately. This may work in many applications, * but more sophisticated users may re-implement this behavior using a thread * pool, a network thread, a request queue, or other mechanism. Advanced * functionality could be built, such as rate-limiting of requests, as per * a specific application's needs. * * @deprecated * * @see RequestListener * The callback interface. * * @author Jim Brusstar (jimbru@fb.com), * Yariv Sadan (yariv@fb.com), * Luke Shepard (lshepard@fb.com) */ @Deprecated public class AsyncFacebookRunner { Facebook fb; public AsyncFacebookRunner(Facebook fb) { this.fb = fb; } /** * Invalidate the current user session by removing the access token in * memory, clearing the browser cookies, and calling auth.expireSession * through the API.
