      • unsubscribe

        public final 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

      • onUnsubscribed

        void onUnsubscribed()

      • isUnsubscribed

        public final 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

      • request

        public final 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

      • onRequested

        void onRequested()

      • setSubscription

        public final void setSubscription​(Subscription s)
        Description copied from interface: AsyncEmitter
        Sets a Subscription on this emitter; any previous Subscription or Cancellation will be unsubscribed/cancelled.
        Specified by:
        setSubscription in interface AsyncEmitter<T>
        Parameters:
        s - the subscription, null is allowed

      • setCancellation

        public final void setCancellation​(AsyncEmitter.Cancellable c)
        Description copied from interface: AsyncEmitter
        Sets a Cancellable on this emitter; any previous Subscription or Cancellation will be unsubscribed/cancelled.
        Specified by:
        setCancellation in interface AsyncEmitter<T>
        Parameters:
        c - the cancellable resource, null is allowed

      • requested

        public final long requested()
        Description copied from interface: AsyncEmitter
        The current outstanding request amount.

        This method it threadsafe.

        Specified by:
        requested in interface AsyncEmitter<T>
        Returns:
        the current outstanding request amount
