Reactive Extensions(Rx)
Rx = Observables + LINQ + Schedulers.
Agenda
- What is Rx?
- How to use Rx?
- Demo time!
- Where to go next?
What is Rx?
"Using Rx, developers represent asynchronous data streams with Observables,
+
+
=
query asynchronous data streams using LINQ operators,
and parameterize the concurrency in the asynchronous data streams using Schedulers."
- Rx README.md
IEnumerable<T>
pull
foreach
IObservable<T>
push
Subscribe(IObserver)
What is Rx?
T Current, bool MoveNext()
throws Exception
returns
OnNext(T)
OnError(Exception)
OnCompleted

How to use Rx?
- Unified Programming Model
- Bridge into the Rx world:
Observable.FromEventPattern
Observable.FromAsync
Observer.Create
Observable.Create
- Subject<T> is Observer and Observable (ReplaySubject, AsyncSubject, BehaviorSubject)
Demo time!
