Abstract Value Members

  1. abstract def complete(): Unit

    Complete the stream normally.

    Complete the stream normally. Use watchCompletion to be notified of this operation’s success.

    Note that this only means the elements have been passed downstream, not that downstream has successfully processed them.

  2. abstract def fail(ex: Throwable): Unit

    Complete the stream with a failure.

    Complete the stream with a failure. Use watchCompletion to be notified of this operation’s success.

    Note that this only means the elements have been passed downstream, not that downstream has successfully processed them.

  3. abstract def offer(elem: T): CompletionStage[QueueOfferResult]

    Method offers next element to a stream and returns future that: - completes with Enqueued if element is consumed by a stream - completes with Dropped when stream dropped offered element - completes with QueueClosed when stream is completed during future is active - completes with Failure(f) when failure to enqueue element from upstream - fails when stream is completed

    Method offers next element to a stream and returns future that: - completes with Enqueued if element is consumed by a stream - completes with Dropped when stream dropped offered element - completes with QueueClosed when stream is completed during future is active - completes with Failure(f) when failure to enqueue element from upstream - fails when stream is completed

    Additionally when using the backpressure overflowStrategy: - If the buffer is full the Future won't be completed until there is space in the buffer - Calling offer before the Future is completed in this case will return a failed Future

    elem

    element to send to a stream

  4. abstract def watchCompletion(): CompletionStage[Done]

    Method returns a CompletionStage that will be completed if this operator completes, or will be failed when the stream fails, for example when SourceQueueWithComplete.fail is invoked.
