Class BufferItemMultiEmitter<T>

  • All Implemented Interfaces:
    ContextSupport, MultiEmitter<T>, org.reactivestreams.Subscription
    public class BufferItemMultiEmitter<T>
extends java.lang.Object

    • Field Detail

      • requested

        protected final java.util.concurrent.atomic.AtomicLong requested

    • Method Detail

      • emit

        public MultiEmitter<T> emit​(T t)
        Description copied from interface: MultiEmitter
        Emits an item event downstream.

        Calling this method after a failure or a completion events has no effect.

        Parameters:
        t - the item, must not be null
        Returns:
        this emitter, so firing item events can be chained.

      • cleanup

        protected void cleanup()

      • failed

        public void failed​(java.lang.Throwable failure)

      • completion

        public void completion()

      • 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.

      • requested

        public long requested()
        Specified by:
        requested in interface MultiEmitter<T>
        Returns:
        the current outstanding request amount.

      • complete

        public void complete()
        Description copied from interface: MultiEmitter
        Emits a completion event downstream indicating that no more item will be sent.

        Calling this method multiple times or after the MultiEmitter.fail(Throwable) method has no effect.

        Specified by:
        complete in interface MultiEmitter<T>

      • isCancelled

        public boolean isCancelled()
        Specified by:
        isCancelled in interface MultiEmitter<T>
        Returns:
        true if the downstream cancelled the stream or the emitter was terminated (with a completion or failure events).

      • fail

        public final void fail​(java.lang.Throwable failure)
        Description copied from interface: MultiEmitter
        Emits a failure event downstream with the given exception.

        Calling this method multiple times or after the MultiEmitter.complete() method has no effect.

        Specified by:
        fail in interface MultiEmitter<T>
        Parameters:
        failure - the exception, must not be null

      • cancel

        public final void cancel()
        Specified by:
        cancel in interface org.reactivestreams.Subscription

      • request

        public final void request​(long n)
        Specified by:
        request in interface org.reactivestreams.Subscription

      • onTermination

        public MultiEmitter<T> onTermination​(java.lang.Runnable onTermination)
        Description copied from interface: MultiEmitter
        Attaches a @{code termination} event handler invoked when the downstream Subscription is cancelled, or when the emitter has emitted either a completion or failure event.

        This method allows cleanup resources once the emitter can be disposed (has reached a terminal state).

        If the registration of the onTermination callback is done after the termination, it invokes the callback immediately.

        Specified by:
        onTermination in interface MultiEmitter<T>
        Parameters:
        onTermination - the action to run on termination, must not be null
        Returns:
        this emitter
