Rx event bus based on RxRelay and custom observer

RxBus

RxBus are RxJava event bus which based on RxRelay and custom LambdaObserver.

RxBus has the following features:

• Observer can only receive items which was emited after subscribed the RxBus.

• Bus never emits error and complete items.

• Don't worry about exception throwed in onNext method of Observer.

• Thread safe.

ObservableUtils utils class can guarantee that Observer can normally receive item after throwing exception in onNext method and then jump to onError method.

Usage

RxBus.get()
    .toObservable(String.class)
    .subscribe(observer1);
// observer1 will receive all string items.

Consumer<String> onNext = new Consumer<String>() {
    @Override
    public void accept(String value) {
        if ("error".equals(value)) throw new IllegalArgumentException("value can not be error !");
        ...
    }
};
// observer2 will throw exception when receive "error" string. after that observer2 can also receive items.
ObservableUtils.subscribe(RxBus.get().toObservable(String.class), onNext);

RxBus.get().post("one");
RxBus.get().post("error");
RxBus.get().post("three");

// observer1 will receive all string items: one, error, three
// observer2 will receive all string items: one, error, three
