Many of these methods use the ListenableFuture API; consult the Guava User Guide article on ListenableFuture . Delegate futures return the same value or throw the same exception as the corresponding input future returns/throws. Cancelling a delegate future has no effect on any input future, since the delegate future does not correspond to a specific input future until the appropriate number of input futures have completed. @PeterLawrey I suppose he needs it for some API that for some twisted reason wants to work with futures even though it really only needs its values.

This class provides a base implementation of Future, with methods to start and cancel a computation, query to see if the computation is complete, and retrieve the result of the computation. The result can only be retrieved when the computation has completed; the get methods will block if the computation has not yet completed. Test doubles: If you need a ListenableFuture for your test, try a SettableFuture or one of the methods in the Futures.immediate* family. Avoid creating a mock or stub Future. Mock and stub implementations are fragile because they assume that only certain methods will be called and because they often implement subtleties of the API improperly. public interface Future.

Callbacks and combinators on futures are a preferred way to use their results. However, blocking may be necessary in certain situations and is supported by the Futures and Promises API.
