rx-scheduler-transformer

Rxjava2 scheduler transformer tools for RxLife in android.

One nice aspect of RxJava is that you can see how data is transformed through a series of operators:

Observable
        .fromCallable(someSource)
        .map(data -> manipulate(data))
        .subscribeOn(Schedulers.io())
        .compose(bindUntilEvent(ActivityEvent.DESTROY))
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(data -> doSomething(data));

We frequently use subscribeOn(), compose() and observeOn() because we want to process data in a worker thread then subscribe to it on the main thread and look up the Activity or Fragment lifecycle. Now, this tiny library get you rid of it!

Setup

compile 'com.github.thepacific:transformer:0.0.1'

Support

Flowable, Observable, Maybe, Single, and Completable are all supported. Implementation is solely based on their Observer types, so conceivably any type that uses those for subscription should work.

CompletableTransformerUtil for Completable
FlowableTransformerUtil for Flowable
MaybeTransformerUtil for Maybe
ObservableTransformerUtil for Observable
SingleTransformerUtil for Single

// Transform schedulers
// from   Schedulers.io()             to   AndroidSchedulers.mainThread()
// from   Schedulers.computation()    to   AndroidSchedulers.mainThread()
// from   Schedulers.trampoline()     to   AndroidSchedulers.mainThread()
// from   Schedulers.newThread()      to   AndroidSchedulers.mainThread()
// from   Schedulers.single()         to   AndroidSchedulers.mainThread()
// from   Schedulers.from(executor)   to   AndroidSchedulers.mainThread()

Usage

// ObservableTransformerUtil.io(lifecycle(), ActivityEvent.DESTROY))
// ObservableTransformerUtil.computation(lifecycle(), ActivityEvent.DESTROY))
// ObservableTransformerUtil.trampoline(lifecycle(), ActivityEvent.DESTROY))
// ObservableTransformerUtil.newThrea(lifecycle(), ActivityEvent.DESTROY))
// ObservableTransformerUtil.single(lifecycle(), ActivityEvent.DESTROY))
// ObservableTransformerUtil.from(executor, lifecycle(), ActivityEvent.DESTROY))

Observable
        .fromCallable(someSource)
        .map(data -> manipulate(data))
        .compose(ObservableTransformerUtil.io(lifecycle(), ActivityEvent.DESTROY))
        .subscribe(data -> doSomething(data));
