Class ObservableStageObserver<T>

java.lang.Object

java.util.concurrent.CompletableFuture<T>

io.reactivex.rxjava3.internal.jdk8.ObservableStageObserver<T>

Type Parameters:

T - the element type

All Implemented Interfaces:

Observer<T>, CompletionStage<T>, Future<T>

Direct Known Subclasses:

ObservableFirstStageObserver, ObservableLastStageObserver, ObservableSingleStageObserver

abstract class ObservableStageObserver<T>
extends CompletableFuture<T>

Method Details

onSubscribe

public final void onSubscribe(@NonNull
 @NonNull Disposable d)

Description copied from interface: Observer

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

Specified by:

onSubscribe in interface Observer<T>

Parameters:

d - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onError

public final void onError(Throwable t)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onComplete().

Specified by:

onError in interface Observer<T>

Parameters:

t - the exception encountered by the Observable

disposeUpstream

protected final void disposeUpstream()

clear

protected final void clear()

cancel

public final boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface Future<T>

Overrides:

cancel in class CompletableFuture<T>

complete

public final boolean complete(T value)

Overrides:

complete in class CompletableFuture<T>

completeExceptionally

public final boolean completeExceptionally(Throwable ex)

Overrides:

completeExceptionally in class CompletableFuture<T>
