      • unsettled

        Collection<IncomingDelivery> unsettled()
        Retrieves the list of unsettled deliveries for this Receiver link which have yet to be settled on this end of the link. When the IncomingDelivery is settled by the receiver the value will be removed from the collection. The Collection returned from this method is a copy of the internally maintained data and is not modifiable. The caller should use this method judiciously to avoid excess GC overhead.
        Returns:
        a collection of unsettled deliveries or an empty list if no pending deliveries are outstanding.
      • hasUnsettled

        boolean hasUnsettled()

      • deliveryReadHandler

        Receiver deliveryReadHandler​(EventHandler<IncomingDelivery> handler)
        Handler for incoming deliveries that is called for each incoming Transfer frame that comprises either one complete delivery or a chunk of a split framed Transfer. The handler should check that the delivery being read is partial or not and act accordingly, as partial deliveries expect additional updates as more frames comprising that IncomingDelivery arrive or the remote aborts the transfer.
        Parameters:
        handler - The handler that will be invoked when Transfer frames arrive on this receiver link.
        Returns:
        this receiver
      • deliveryAbortedHandler

        Receiver deliveryAbortedHandler​(EventHandler<IncomingDelivery> handler)
        Handler for aborted deliveries that is called for each aborted in-progress delivery.

        This handler is an optional convenience handler that supplements the standard deliveryReadHandler(EventHandler) in cases where the users wishes to break out the processing of inbound delivery data from abort processing. If this handler is not set the Receiver will call the registered deliveryAbortedHandler(EventHandler) if one is set.

        Parameters:
        handler - The handler that will be invoked when Transfer frames arrive on this receiver link.
        Returns:
        this receiver
      • deliveryStateUpdatedHandler

        Receiver deliveryStateUpdatedHandler​(EventHandler<IncomingDelivery> handler)
        Handler for updates to the remote state of incoming deliveries that have previously been received.

        Remote state updates for an IncomingDelivery can happen when the remote settles a complete IncomingDelivery or otherwise modifies the delivery outcome and the user needs to act on those changes such as a spontaneous update to the DeliveryState.

        Parameters:
        handler - The handler that will be invoked when a new remote state update for an IncomingDelivery arrives on this link.
        Returns:
        this receiver
