Package io.reactivex.rxjava3.internal.operators.maybe

Class MaybeUsing<T,D>

java.lang.Object

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

io.reactivex.rxjava3.internal.operators.maybe.MaybeUsing<T,D>

Type Parameters:

T - the value type

D - the resource type

All Implemented Interfaces:

MaybeSource<T>

public final class MaybeUsing<T,D>
extends Maybe<T>

Creates a resource and a dependent Maybe for each incoming Observer and optionally disposes the resource eagerly (before the terminal event is send out).

Method Detail

subscribeActual

protected void subscribeActual(MaybeObserver<? super T> 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<T>

Parameters:

observer - the MaybeObserver to handle, not null
