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.

failed

public void failed(Throwable failure)

completion

public void completion()

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(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(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

serialize

public MultiEmitter<T> serialize()
