RxAnnotations: Annotations for RxJava

Generating reactiveX methods using annotations.

Getting started

The first step is to include RxAnnotations into your project, for example, as a Gradle compile dependency:

provided 'com.juliusscript.rxannotation:rxannotations:0.0.2'
apt 'com.juliusscript.rxannotation:rxannotations:0.0.2'
//or
annotationProcessor 'com.juliusscript.rxannotation:rxannotations:0.0.2'

If you haven't yet include RxJava and/or RxAndroid:

compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.1.0'

As Maven dependency:

<dependency>
  <groupId>com.juliusscript.rxannotation</groupId>
  <artifactId>rxannotations</artifactId>
  <version>0.0.2</version>
  <type>pom</type>
</dependency>

Use RxAnnotations to wrap existing class and methods:

@Singleton
@RxClass
public class Api {
    private boolean completed;

    @RxObservable
    public String getValue(String whut) {
        return null;
    }


    @RxObservable(defer = true)
    public Integer getInteger() {
        //could be network request or anything that shouldn't run on main thread
        return 55;
    }

    @RxSingle
    public Float getFloat() {
        return 0.5f;
    }
    
    @RxFlowable(backpressure = BackpressureStrategy.ERROR)
    public Object getObject() {
        return new Object();
    }

    @RxMaybe
    public Integer maybe() {
        if (BuildConfig.DEBUG) {
            return 1;
        } else {
            return 0;
        }
    }

    @RxCompletable
    public void setCompleted() {
        completed = true;
    }
}

@Singleton Creates, well...singleton of annotated class.

In order to produce Observables and Singles class has to be annotated as @RxClass.

Code generated from above annotation could be referenced in old way and as observables or singles.

Using method from generated class:

 RxApi.getInstance().getIntegerRx()
                .subscribeOn(Schedulers.io())
                .subscribe(new Consumer<Integer>() {
                    @Override
                    public void accept(@NonNull Integer integer) throws Exception {
                        Toast.makeText(MainActivity.this, "Integer value is: " + integer, Toast.LENGTH_SHORT).show();
                    }
                });

or non-reactiveX way RxApi.getInstance().getInteger();
