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

All Implemented Interfaces:
Future<V>, ListenableFuture<V>
```
public class AsyncResult<V>
extends Object
implements ListenableFuture<V>
```
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
