Computes a value, possibly asynchronously. For an example usage and more information, see Futures.FutureCombiner.callAsync(AsyncCallable).

Much like Callable, but returning a ListenableFuture result.

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
