Class MetroIIPNQueueReceiver

  • All Implemented Interfaces:
    ProcessReceiver, Receiver

    public class MetroIIPNQueueReceiver
    extends PNQueueReceiver

    MetroIIPNQueueReceiver adapts token transfer to MetroII semantics. Each get() or put() is associated with two MetroII events. The data token transfer will not occur until the associated MetroII events are NOTIFIED.

    The implementation is obsolete and needs to be updated.
