Interface AsyncCallable<V extends @Nullable Object>

@GwtCompatible
public interface AsyncCallable<V extends @Nullable 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.

call

ListenableFuture<V> call()
                  throws 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:
