  extended by javax.ejb.AsyncResult<V>
All Implemented Interfaces:
java.io.Serializable, java.util.concurrent.Future<V>

public final class AsyncResult<V>
extends java.lang.Object
implements java.util.concurrent.Future<V>, java.io.Serializable

Wraps the result of an asynchronous method call as a Future object preserving compatability with the business interface signature. The value specified in the constructor will be retrieved by the container and made available to the client.
