See: Description

Interface Summary

Interface	Description
Observable.OnSubscribe<T>	Invoked when Observable.subscribe is called.
Observable.Operator<R,T>	Operator function for lifting into an Observable.
Observable.Transformer<T,R>	Transformer function used by Observable.compose(rx.Observable.Transformer<? super T, ? extends R>).
Observer<T>	Provides a mechanism for receiving push-based notifications.
Producer
Single.OnSubscribe<T>	Invoked when Single.execute is called.
Single.Transformer<T,R>	Transformer function used by Single.compose(rx.Single.Transformer<? super T, ? extends R>).
Subscription	Subscription returns from Observable.subscribe(Subscriber) to allow unsubscribing.

Class Summary

Class	Description
Notification<T>	An object representing a notification sent to an Observable.
Observable<T>	The Observable class that implements the Reactive Pattern.
Scheduler	A Scheduler is an object that schedules units of work.
Scheduler.Worker	Sequential Scheduler for executing actions on a single thread or event loop.
Single<T>	The Single class implements the Reactive Pattern for a single value response.
SingleSubscriber<T>	Provides a mechanism for receiving push-based notifications.
Subscriber<T>	Provides a mechanism for receiving push-based notifications from Observables, and permits manual unsubscribing from these Observables.

Package rx Description

Rx Observables

A library that enables subscribing to and composing asynchronous events and callbacks.

The Observable/Observer interfaces and associated operators (in the .operations package) are inspired by and attempt to conform to the Reactive Rx library in Microsoft .Net.

More information can be found at http://msdn.microsoft.com/en-us/data/gg577609.

Compared with the Microsoft implementation:

• Observable == IObservable
• Observer == IObserver
• Subscription == IDisposable
• ObservableExtensions == Observable

Services which intend on exposing data asynchronously and wish to allow reactive processing and composition can implement the Observable interface which then allows Observers to subscribe to them and receive events.

Usage examples can be found on the Observable and Subscriber classes.
