# RxKeepOrder

keeps ordering of RxJava Streams(Observable, Flowable, Single and Maybe)

## motivation

concatArrayEager is so useful. But doesn't support multi observable type(Observable, Flowable, Completable and Maybe)

This library can be executed parallel and keep order emit items multi observable types!!

## usage

Java simple example.

```java

// set default observeOn scheduler, almost mainThread when Android Platform

seed = RxKeepOrder().setObserveScheduler(AndroidSchedulers.mainThread());

// evaluate parallel observable1, observable2 and observable3

// But evaluate subscribe keep order!!

observable1

    .compose(seed.attach())

    .subscribe();

observable2

    .compose(seed.attach())

    .subscribe();

observable3

    .compose(seed.attach())

    .subscribe();

...

```

Kotlin simple example.

```kotlln

// set default observeOn scheduler, almost mainThread when Android Platform

seed = RxKeepOrder().setObserveScheduler(AndroidSchedulers.mainThread());

// evaluate parallel observable1, observable2 and observable3

// But evaluate subscribe keep order!!

observable1

    .keepOrder(seed)

    .subscribe();

observable2

    .keepOrder(seed)

    .subscribe();

observable3

    .keepOrder(seed)

    .subscribe();

...

```
