Package org.springframework.scheduling.annotation

Class AsyncResult<V>

java.lang.Object

org.springframework.scheduling.annotation.AsyncResult<V>

Type Parameters:

V - the value type

All Implemented Interfaces:

Future<V>, ListenableFuture<V>

@Deprecated
public class AsyncResult<V>
extends Object
implements ListenableFuture<V>

Deprecated.

as of 6.0, in favor of CompletableFuture

A pass-through Future handle that can be used for method signatures which are declared with a Future return type for asynchronous execution.

As of Spring 4.1, this class implements ListenableFuture, not just plain Future, along with the corresponding support in @Async processing.

As of Spring 4.2, this class also supports passing execution exceptions back to the caller.

Since:

3.0
