Our Publisher is subscribed to multiple times. If every subscriber sets a filter when subscribing to events, does this filter only affect this subscriber? Or does it affect all subscribers?

Let's test:

public class RxJava_filter implements Consumer<RxBus.Event>, Predicate<RxBus.Event> {
    public static void main(String[] args) {
        RxJava_filter rf = new RxJava_filter();
        RxBus.get().toFlowable(RxBus.Event.class).filter(rf).subscribe(rf);
        RxBus.get().post(2, 2);
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                RxBus.get().toFlowable(RxBus.Event.class).filter(new Predicate<RxBus.Event>() {
                    @Override
                    public boolean test(RxBus.Event e) throws Exception {
                        return false;
                    }
                }).subscribe(new Consumer<RxBus.Event>() {
                    @Override
                    public void accept(RxBus.Event e) {
                        System.out.println(e.what + "I filtered you\n");
                    }
                });
                RxBus.get().post(2, 2);
            }
        }).start();
    }

    @Override
    public void accept(RxBus.Event e) throws Exception {
        System.out.println(e.object + "I show you\n");
    }

    @Override
    public boolean test(RxBus.Event e) throws Exception {
        if (e.what == 2) return true;
        return false;
    }
}

Test results:

2I show you

2I show you

Process finished with exit code 0

Test ideas:
Once the program has started, add a subscriber and send the event, we have the first print: 2 I show you
Then every five seconds, we add another subscriber, set a filter at the same time, and then publish the event again
So we had a second print: "2 I show you“

But the subscriber we set later didn't print it. It was filtered out. The subscriber we set earlier can print

Conclusion:
Each time the filter is set, it will only affect the subscribers of this time, and other subscribers will not be impressed.
