flatMap

public static <T,R> MaybeTransformer<T,R> flatMap(Function<? super T,? extends MaybeSource<? extends R>> onSuccessHandler,
                                                  Function<? super Throwable,? extends MaybeSource<? extends R>> onErrorHandler,
                                                  Callable<? extends MaybeSource<? extends R>> onCompleteHandler)

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

Type Parameters:

T - the success type of the upstream

R - the success type of the resulting Maybe

Parameters:

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

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

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

Returns:

the new MaybeTransformer instance
