Transcript

  • 1. Reactive Extensions for .NET Andrei Marukovich contact@lunarfrog.com twitter: @amarukovich
  • 2. Rx is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators. Rx = Observables + LINQ + Schedulers
  • 3. Observables • IObservable<T> • IObserver<T>
  • 4. Enumerables interface IEnumerable<out T> { IEnumerator<T> GetEnumerator(); } interface IEnumerator<out T> : IDisposable { T Current { get; } bool MoveNext(); void Reset(); }
  • 5. Pull and Push Consumer Pull Any new data? IEnumerable • • • • Sensors UI events Web services Social media Source IObservable Push New data available!
  • 6. Observables interface IObservable<out T> { IDisposable Subscribe(IObserver<T> observer); } interface IObserver<out T> { void OnNext(T value); void OnError(Exception error); void OnCompleted(); }
  • 7. Using observables IObservable IObserver Subscribe OnNext OnNext OnComplete
  • 8. Contract OnNext* [OnComplete | OnError] 1 2 1 3 2 1 2 1 2 3 4 3 3 4 4 5 6
  • 9. Demo: Observable sequences • Subject<T> • Observable • Never, Empty, Return, Throw, Create • Range, Generate, Repeat • Interval, Timer
  • 10. LINQ Filtering • Where, Distinct, Skip(While|Last|Until), Take Inspection • Any, All Aggregation and transformation • Count, Min, Max, Average, Select
  • 11. Demo: LINQ • Common LINQ operators • Combining sequences • Pairing • Sequentially • Concurrently
  • 12. Rx bridges • Observable.FromAsync() • Observable.FromEvent() • Observable.FromEventPattern()
  • 13. Demo: LINQ to events • Time shifting • Throttle • Sample • Buffer • Delay
  • 14. Concurrency SubscribeOn • Invocation of the subscription ObserveOn • Observing of notifications
  • 15. Demo: Concurrency • Schedulers
  • 16. Schedulers • ImmediateScheduler • CurrentThreadScheduler • DispatcherScheduler • EventLoopScheduler • NewThreadScheduler • Thread/Task Pool • TestScheduler
  • 17. Flavors of Rx .NET • WinForms, WPF, Silverlight • Windows Phone, WinRT • ASP .NET Beyond .NET • RxJS, RxCpp • RxPy, Rx.rb
  • 18. Resources • http://rx.codeplex.com/ • http://bit.ly/Rx-Home
  • 19. Thank you! Andrei Marukovich contact@lunarfrog.com twitter: @amarukovich
