Class AsyncResult<T>

java.lang.Object
  org.jboss.seam.cron.api.asynchronous.AsyncResult<T>

All Implemented Interfaces:

Future<T>

public class AsyncResult<T>
extends Object
implements Future<T>

This is a convenience implementation of #Future which can be used as the return value of an @#Asynchronous method. This is useful because it prompts Seam Cron to re-wrap the asynchronous method execution in a legitimate #FutureTask and return that immediately to the calling method.
