ItemSalesListenerProxy provides a proxy object for remote listeners to monitor the Item events of its associated terminal session.
Remote proxy objects extend the appropriate RMI server classes which handle the RMI duties for the client (so the client does not need to deal with rmi server issues). The proxy objects also perform the role of event dispatching.
By default, the listener proxy object will perform event queuing on an AEF event thread. This relieves the client of any "thread swapping" responsibilities and insures that the AEF event dispatching performance is not affected by client processing. To override this default behavior, use the setDispatchQueue() method. The proxy utilizes the EventDispatcher for queueing event listener notification.
To use a proxy object, the client must implement the listener interface and get the POSDataProvider object from the AEFSession to monitor. The proxy object is then constructed passing a reference to the client and the data provider. The proxy object performs the listener registration and forwards all events from the data provider to the client.
