- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public static interface ClosingFuture.Combiner.CombiningCallable<V extends @Nullable Object>An operation that returns a result and may throw an exception.
V call(ClosingFuture.DeferredCloser closer, ClosingFuture.Peeker peeker) throws ExceptionComputes a result, or throws an exception if unable to do so.
Any objects that are passed to
closer.eventuallyClose()will be closed when the
ClosingFuturepipeline is done (but not before this method completes), even if this method throws or the pipeline is cancelled.
peeker- used to get the value of any of the input futures
