Class MaybeFlatMapBiSelector<T,U,R>

java.lang.Object

io.reactivex.rxjava3.core.Maybe<R>

io.reactivex.rxjava3.internal.operators.maybe.MaybeFlatMapBiSelector<T,U,R>

Type Parameters:

T - the main value type

U - the second value type

R - the result value type

All Implemented Interfaces:

MaybeSource<R>, HasUpstreamMaybeSource<T>

public final class MaybeFlatMapBiSelector<T,U,R>
extends Maybe<R>

Maps a source item to another MaybeSource then calls a BiFunction with the original item and the secondary item to generate the final result.

Method Details

subscribeActual

protected void subscribeActual(MaybeObserver<? super R> observer)

Description copied from class: Maybe

Implement this method in subclasses to handle the incoming MaybeObservers.

There is no need to call any of the plugin hooks on the current Maybe instance or the MaybeObserver; all hooks and basic safeguards have been applied by Maybe.subscribe(MaybeObserver) before this method gets called.

Specified by:

subscribeActual in class Maybe<R>

Parameters:

observer - the MaybeObserver to handle, not null

source

public final MaybeSource<T> source()

Description copied from interface: HasUpstreamMaybeSource

Returns the upstream source of this Maybe.

Allows discovering the chain of observables.

Specified by:

source in interface HasUpstreamMaybeSource<T>

Returns:

the source MaybeSource
