public class GUIServices_impl
extends java.lang.Object
implements SnwGUIServicesServer

Class GUIServices implements the GUI services. All the methods could potentially return an empty string. This universally occurs when one of these methods is called after the disconnect() method is called and before the server has time to realize it should no longer be accepting connections. Some of the methods may return empty strings for other reasons as well.
