我理解的Rxjava

通过两个线索来理解rxjava原理

线索一：订阅流程 subscribe

线索二：事件执行流程 以onNext为例

示例代码：

Observable.create(
                new ObservableOnSubscribe<String>() {
                    @Override
                    public void subscribe(ObservableEmitter<String> emitter) throws Exception {
                        emitter.onNext("rxjava");
                    }
                }
         )
        .map(new Function<String, String>() {
            @Override
            public String apply(String s) throws Exception {
                return s + " map1 ";
            }
        })
        .map(new Function<String, String>() {
            @Override
            public String apply(String s) throws Exception {
                return s + " map2 ";
            }
        })
        .subscribe(
                new Observer<String>() {
                    @Override
                    public void onSubscribe(Disposable d) {
                    }
                    @Override
                    public void onNext(String s) {
                    }
                    @Override
                    public void onError(Throwable e) {
                    }
                    @Override
                    public void onComplete() {
                    }
                });
