Interface sunw.demo.quote.QuoteListener

public interface QuoteListener
extends Remote
This is the java.rmi.Remote interface that QuoteListeners must implement. QuoteListeners monitor a single stock, QuoteEvents are delivered whenever new data for that stock is available. The standard event mechanism is used for QuoteEvents with one wrinkle: QuoteListener implementations must extend UnicastRemoteObject.
