MultiSubscriberAdapter

public MultiSubscriberAdapter(java.util.concurrent.Flow.Subscriber<? super T> downstream)

Method Detail

onSubscribe

public void onSubscribe(java.util.concurrent.Flow.Subscription subscription)

Specified by:

onSubscribe in interface java.util.concurrent.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(java.lang.Throwable failure)

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:

failure - 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>

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.
