RxJava2 ready !

Android app on Google Play

Create an interface with @Observe annotated method

public class User {

       private int age;

       @Observe
       public int getAge() {
           return age;
       }

       @Observe
       public void setAge(int age) {
           this.age = age;
       }

}

Will generate 2 observables

Observable<Integer> getAge()

Observable<T> setAge(T toReturn, int age)

setAge is a void method so it will return the first T toReturn argument (useful for your flatmaps)

Those observable are accessible through Rx.observe(user)

Static

public class Calculator {

    @Observe
    public static int addOne(int number) {
        return number + 1;
    }

}

Will generate

Observable<T> addOne(int age)

Accessible through Rx.observeCalculator()

Example

User user = new User();

Rx.observe(user).setAge(user, 3)
         .flatMap(u -> Rx.observe(u).getAge())
         .flatMap(age -> Rx.observeCalculator().addOne(age))

         .subscribeOn(Schedulers.newThread())
         .observeOn(AndroidSchedulers.mainThread())

         .subscribe(integer -> {
             Toast.makeText(getBaseContext(), "" + integer, Toast.LENGTH_SHORT).show();
         });

RxJava2

Rx.Observable is also compatible with @Single, @Flowable, @Completable
