Package jakarta.ejb

Class AsyncResult<V>

java.lang.Object

jakarta.ejb.AsyncResult<V>

Type Parameters:

V - The result type returned by this Future's get method

All Implemented Interfaces:

Future<V>

public final class AsyncResult<V>
extends Object
implements Future<V>

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.

Note that this object is not passed to the client. It is merely a convenience for providing the result value to the container. Therefore, none of its instance methods should be called by the application.

Since:

EJB 3.1
