DurianRx: Reactive getters, powered by RxJava and ListenableFuture

Maven central Apache 2.0

Changelog Javadoc Live chat JitCI

DurianRx unifies RxJava's Observable with Guava's ListenableFuture. If you happen to be using SWT as a widget toolkit, then you'll want to look at DurianSwt as well.

Observable<SomeType> observable = someObservable();
ListenableFuture<SomeType> future = someFuture();
Rx.subscribe(observable, val -> doSomething(val));
Rx.subscribe(future, val -> doSomething(val));

It also provides reactive getters, a simple abstraction for piping data which allows access via T get() or Observable<T> asObservable().

RxBox<Point> mousePos = RxBox.of(new Point(0, 0));
this.addMouseListener(e -> mousePos.set(new Point(e.x, e.y)));

Rectangle hotSpot = new Rectangle(0, 0, 10, 10)
RxGetter<Boolean> isMouseOver = mousePos.map(hotSpot::contains);

Debugging an error which involves lots of callbacks can be difficult. To make this easier, DurianRx includes a tracing capability, which makes this task easier.

// anytime an error is thrown in an Rx callback, the stack trace of the error
// will be wrapped by the stack trace of the original subscription
DurianPlugins.register(RxTracingPolicy.class, new LogSubscriptionTrace()).

DurianRx's only requirements are durian-base, durian-collect, durian-concurrent, and RxJava.
