Usage

Convert between the reactive base types

importhu.akarnokd.rxjava3.interop.RxJavaInterop;
// convert from 1.x to 3.xio.reactivex.rxjava3.core.Flowablef3 = RxJavaInterop.toV3Flowable(rx.Observable);
io.reactivex.rxjava3.core.Observableo3 = RxJavaInterop.toV3Observable(rx.Observable);
io.reactivex.rxjava3.core.Singles3 = RxJavaInterop.toV3Single(rx.Single);
io.reactivex.rxjava3.core.Completablec3 = RxJavaInterop.toV3Completable(rx.Completable);
io.reactivex.rxjava3.core.Maybem3s = RxJavaInterop.toV3Maybe(rx.Single);
io.reactivex.rxjava3.core.Maybem3c = RxJavaInterop.toV3Maybe(rx.Completable);
// convert from 3.x to 1.xrx.Observableo1 = RxJavaInterop.toV1Observable(Publisher);
rx.Observableq1 = RxJavaInterop.toV1Observable(ObservableSource, BackpressureStrategy);
rx.Singles1 = RxJavaInterop.toV1Single(SingleSource);
rx.Completablec1 = RxJavaInterop.toV1Completable(CompletableSource);
rx.Singles1m = RxJavaInterop.toV1Single(MaybeSource);
rx.Completablec1m = RxJavaInterop.toV1Completable(MaybeSource);

Convert between Subjects and Processors.

Note that 3.x Subjects and FlowableProcessors support only the same input and output types.

// convert from 1.x to 3.xio.reactivex.rxjava3.subjects.Subjectsj3 = RxJavaInterop.toV3Subject(rx.subjects.Subject);
io.reactivex.rxjava3.processors.FlowableProcessorfp3 = RxJavaInterop.toV3Processor(rx.subjects.Subject);
// convert from 3.x to 1.xrx.subjects.Subjectsj1 = RxJavaInterop.toV1Subject(io.reactivex.rxjava3.subjects.Subject);
rx.subjects.Subjectsj1b = RxJavaInterop.toV1Subject(io.reactivex.rxjava3.processors.FlowableProcessor);

Convert between 1.x X.Transformers and 3.x XTransformers.

// convert from 1.x to 3.xio.reactivex.rxjava3.core.FlowableTransformerft3 = RxJavaInterop.toV3Transformer(
rx.Observable.Transformer);
io.reactivex.rxjava3.core.ObservableTransformerot3 = RxJavaInterop.toV3Transformer(
rx.Observable.Transformer, io.reactivex.rxjava3.core.BackpressureStrategy);
io.reactivex.rxjava3.core.SingleTransformerst3 = RxJavaInterop.toV3Transformer(
rx.Single.Transformer);
io.reactivex.rxjava3.core.CompletableTransformerct3 = RxJavaInterop.toV3Transformer(
rx.Completable.Transformer);
// convert from 3.x to 1.xrx.Observable.Transformerft1 = RxJavaInterop.toV1Transformer(
io.reactivex.rxjava3.core.FlowableTransformer);
rx.Observable.Transformerot1 = RxJavaInterop.toV1Transformer(
io.reactivex.rxjava3.core.ObservableTransformer,
io.reactivex.rxjava3.core.BackpressureStrategy);
rx.Single.Transformerst1 = RxJavaInterop.toV1Transformer(
io.reactivex.rxjava3.core.SingleTransformer);
rx.Completable.Transformerct1 = RxJavaInterop.toV1Transformer(
io.reactivex.rxjava3.core.CompletableTransformer);

Convert between 1.x Flowable.Operator and 3.x FlowableOperator

// convert from 1.x to 3.xio.reactivex.rxjava3.core.FlowableOperatorfo3 = RxJavaInterop.toV3Operator(rx.Observable.Operator);
// convert from 3.x to 1.xrx.Observable.Operatorfo1 = RxJavaInterop.toV1Operator(io.reactivex.rxjava3.core.FlowableOperator);

Convert between 1.x Subscription and 3.x Disposable

// convert from 1.x to 3.xio.reactivex.rxjava3.disposables.Disposabled3 = RxJavaInterop.toV3Disposable(rx.Subscription);
// convert from 3.x to 1.xrx.Subscriptions1 = RxJavaInterop.toV1Subscription(io.reactivex.rxjava3.disposables.Disposable);

Convert between 1.x Schedulers and 3.x Schedulers

// convert from 1.x to 3.xio.reactivex.rxjava3.core.Schedulers3 = RxJavaInterop.toV3Scheduler(rx.Scheduler);
// convert from 3.x to 1.xrx.Schedulers1 = RxJavaInterop.toV1Scheduler(io.reactivex.rxjava3.core.Scheduler);
