AsyncCallable (Guava: Google Core Libraries for Java 33.0.0-jre API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
@GwtCompatible
public interface AsyncCallable<V extends @Nullable java.lang.Object>
```
Computes a value, possibly asynchronously. For an example usage and more information, see Futures.FutureCombiner.callAsync(AsyncCallable, java.util.concurrent.Executor).
Much like Callable, but returning a ListenableFuture result.

- Method Summary
  
  All Methods Instance Methods Abstract Methods
  Modifier and Type Method Description
  
  ListenableFuture<V> call()
  Computes a result Future.

- Method Detail
  - call
```
ListenableFuture<V> call()
                  throws java.lang.Exception
```
    Computes a result Future. The output Future need not be done, making AsyncCallable suitable for asynchronous derivations.
    Throwing an exception from this method is equivalent to returning a failing ListenableFuture.
    
    Throws:
    
    java.lang.Exception
