Abstract Value Members

  1. 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

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

    Method returns a CompletionStage that will be completed if this operator completes, or will be failed when the stream is failed.
