    • LatestCoordinator

      public LatestCoordinator(Subscriber<? super R> actual, FuncN<? extends R> combiner, int count, int bufferSize, boolean delayError)
  • Method Details

    • subscribe

      public void subscribe(Observable<? extends T>[] sources)
    • request

      public void request(long n)
      Description copied from interface: Producer
      Request a certain maximum number of items from this Producer. This is a way of requesting backpressure. To disable backpressure, pass Long.MAX_VALUE to this method.

      Requests are additive but if a sequence of requests totals more than Long.MAX_VALUE then Long.MAX_VALUE requests will be actioned and the extras may be ignored. Arriving at Long.MAX_VALUE by addition of requests cannot be assumed to disable backpressure. For example, the code below may result in Long.MAX_VALUE requests being actioned only.

       request(100);
       request(Long.MAX_VALUE-1);
       
      Specified by:
      request in interface Producer
      Parameters:
      n - the maximum number of items you want this Producer to produce, or Long.MAX_VALUE if you want the Producer to produce items at its own pace
    • unsubscribe

      public void unsubscribe()
      Description copied from interface: Subscription
      Stops the receipt of notifications on the Subscriber that was registered when this Subscription was received.

      This allows unregistering an Subscriber before it has finished receiving all events (i.e. before onCompleted is called).

      Specified by:
      unsubscribe in interface Subscription
    • isUnsubscribed

      public boolean isUnsubscribed()
      Description copied from interface: Subscription
      Indicates whether this Subscription is currently unsubscribed.
      Specified by:
      isUnsubscribed in interface Subscription
      Returns:
      true if this Subscription is currently unsubscribed, false otherwise
    • cancel

      void cancel(Queue<?> q)
    • combine

      void combine(Object value, int index)
      Combine the given notification value from the indexth source with the existing known latest values.
      Parameters:
      value - the notification to combine, null indicates the source terminated normally
      index - the index of the source subscriber
    • drain

      void drain()
    • checkTerminated

      boolean checkTerminated(boolean mainDone, boolean queueEmpty, Subscriber<?> childSubscriber, Queue<?> q, boolean delayError)
    • onError

      void onError(Throwable e)
