Method Summary

Modifier and Type	Method and Description
static <T> MaybeConverter<T,Completable>	flatMapCompletable(Function<? super T,? extends CompletableSource> onSuccessHandler, Function<? super Throwable,? extends CompletableSource> onErrorHandler, Callable<? extends CompletableSource> onCompleteHandler) Maps the terminal signals of the upstream into CompletableSources and subscribes to it, relaying its terminal events to the downstream.
static <T,R> MaybeConverter<T,Flowable<R>>	flatMapFlowable(Function<? super T,? extends Publisher<? extends R>> onSuccessHandler, Function<? super Throwable,? extends Publisher<? extends R>> onErrorHandler, Callable<? extends Publisher<? extends R>> onCompleteHandler) Maps the terminal signals of the upstream into Publishers and subscribes to it, relaying its terminal events to the downstream.
static <T,R> MaybeConverter<T,Observable<R>>	flatMapObservable(Function<? super T,? extends ObservableSource<? extends R>> onSuccessHandler, Function<? super Throwable,? extends ObservableSource<? extends R>> onErrorHandler, Callable<? extends ObservableSource<? extends R>> onCompleteHandler) Maps the terminal signals of the upstream into ObservableSources and subscribes to it, relaying its terminal events to the downstream.
static <T,R> MaybeConverter<T,Single<R>>	flatMapSingle(Function<? super T,? extends SingleSource<? extends R>> onSuccessHandler, Function<? super Throwable,? extends SingleSource<? extends R>> onErrorHandler, Callable<? extends SingleSource<? extends R>> onCompleteHandler) Maps the terminal signals of the upstream into SingleSources and subscribes to it, relaying its terminal events to the downstream.

Method Detail

flatMapCompletable

public static <T> MaybeConverter<T,Completable> flatMapCompletable(Function<? super T,? extends CompletableSource> onSuccessHandler,
                                                                   Function<? super Throwable,? extends CompletableSource> onErrorHandler,
                                                                   Callable<? extends CompletableSource> onCompleteHandler)

Maps the terminal signals of the upstream into CompletableSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a CompletableSource to continue with.

onErrorHandler - called when the upstream fails and should return the CompletableSource for the given Throwable instance to continue with.

onCompleteHandler - called when the upstream completes normally and should return the CompletableSource to continue with.

Returns:

the new MaybeConverter instance

Since:

0.20.2

flatMapSingle

public static <T,R> MaybeConverter<T,Single<R>> flatMapSingle(Function<? super T,? extends SingleSource<? extends R>> onSuccessHandler,
                                                              Function<? super Throwable,? extends SingleSource<? extends R>> onErrorHandler,
                                                              Callable<? extends SingleSource<? extends R>> onCompleteHandler)

Maps the terminal signals of the upstream into SingleSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

R - the element type of the mapped-in SingleSource

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a SingleSource to continue with.

onErrorHandler - called when the upstream fails and should return the SingleSource for the given Throwable instance to continue with.

onCompleteHandler - called when the upstream completes normally and should return the SingleSource to continue with.

Returns:

the new MaybeConverter instance

Since:

0.20.2

flatMapObservable

                                                                      Callable<? extends ObservableSource<? extends R>> onCompleteHandler)

Maps the terminal signals of the upstream into ObservableSources and subscribes to it, relaying its terminal events to the downstream.

Type Parameters:

T - the upstream success value type

R - the element type of the mapped-in ObservableSource

Parameters:

onSuccessHandler - a function called with the upstream success value and should return a ObservableSource to continue with.

onErrorHandler - called when the upstream fails and should return the ObservableSource for the given Throwable instance to continue with.

onCompleteHandler - called when the upstream completes normally and should return the ObservableSource to continue with.

Returns:

the new MaybeConverter instance
