Method Detail

create

public static <T> MultiEmitterProcessor<T> create()

emit

public MultiEmitter<T> emit(T item)

Description copied from interface: MultiEmitter

Emits an item event downstream.

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

Specified by:

emit in interface MultiEmitter<T>

Parameters:

item - the item, must not be null

Returns:

this emitter, so firing item events can be chained.

fail

public void fail(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

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>

onTermination

public MultiEmitter<T> onTermination(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).

Specified by:

onTermination in interface MultiEmitter<T>

Parameters:

onTermination - the action to run on termination, must not be null

Returns:

this emitter

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).

requested

public long requested()

Specified by:

requested in interface MultiEmitter<T>

Returns:

the current outstanding request amount.

subscribe

public void subscribe(org.reactivestreams.Subscriber<? super T> subscriber)

Specified by:

subscribe in interface org.reactivestreams.Publisher<T>

onSubscribe

public void onSubscribe(org.reactivestreams.Subscription subscription)

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<T>

onNext

public void onNext(T item)

Specified by:

onNext in interface org.reactivestreams.Subscriber<T>

onError

public void onError(Throwable failure)

Specified by:

onError in interface org.reactivestreams.Subscriber<T>

onComplete

public void onComplete()

Specified by:

onComplete in interface org.reactivestreams.Subscriber<T>

toMulti

public Multi<T> toMulti()
