CallbackBasedSubscriber

public CallbackBasedSubscriber(Context context,
 Consumer<? super T> onItem,
 Consumer<? super Throwable> onFailure,
 Runnable onCompletion,
 Consumer<? super Flow.Subscription> onSubscription)

Method Details

context

public Context context()

Description copied from interface: ContextSupport

Provide a context.

Since calls to this method shall only be triggered when a Mutiny pipeline uses a withContext operator, there is no need in general for caching the context value in a field of the implementing class. Exceptions include operators that have cross-subscriber semantics such as memoizers or broadcasters.

This method is expected to be called once per withContext operator.

Specified by:

context in interface ContextSupport

Returns:

the context, must not be null.

onSubscribe

public void onSubscribe(Flow.Subscription s)

Specified by:

onSubscribe in interface Flow.Subscriber<T>

onItem

public void onItem(T item)

Description copied from interface: MultiSubscriber

Method called when the upstream emits an item event, in response to to requests to Flow.Subscription.request(long).

Specified by:

onItem in interface MultiSubscriber<T>

Parameters:

item - the item, must not be null.

onFailure

public void onFailure(Throwable t)

Description copied from interface: MultiSubscriber

Method called when the upstream emits a failure terminal event.

No further events will be sent even if Flow.Subscription.request(long) is invoked again.

Specified by:

onFailure in interface MultiSubscriber<T>

Parameters:

t - the failure, must not be null.

onCompletion

public void onCompletion()

Description copied from interface: MultiSubscriber

Method called when the upstream emits a completion terminal event.

No further events will be sent even if Flow.Subscription.request(long) is invoked again.

Specified by:

onCompletion in interface MultiSubscriber<T>

request

public void request(long n)

Specified by:

request in interface Flow.Subscription

cancel

public void cancel()

Description copied from interface: Cancellable

Runs the cancellation action.

Specified by:

cancel in interface Cancellable

Specified by:

cancel in interface Flow.Subscription
