Examples of DeferredReturnFuture

org.infinispan.util.concurrent.DeferredReturnFuture
This is a notifying and notifiable future whose return value is not known at construction time. Instead, the return value comes from the result of the operation called in the Callable or Runnable. @author Galder Zamarreño @since 5.0
