For example, why doesn't the following get printed? print "\n-------------------------------------------------\n" Anyway, I need to get a better understand of deferred before I can decide whether deferred should be implemented or not. > > -- > Trustin Lee - http://gleamynode.net/ > > > _______________________________________________ > infinispan-dev mailing list > infinispan-dev(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/infinispan-dev -- Galder Zamarreño Sr. Software Engineer Infinispan, JBoss Cache _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev

Deferred is not different from NotifyingFuture fundamentally. The only difference is how it handles an exceptional case and callbacks can return another Deffered, which makes chained asynchronous operations possible. This difference opens a lot of possibilities for performing a series of asynchronous operations. It can be compared to dynamic construction of interceptor chains. So, I'd like to propose to replacing the current NotifyingFuture implementation with Deferred. I think the name 'Deferred' is somewhat less intuitive, so retaining the name might be a good idea.
