Class OptionEvent

java.lang.Object
gnu.dtools.ritopt.OptionEvent
public class OptionEvent extends Object
An event indicating that an option has been invoked. When an OptionListener is notified by a NotifyOption, it passes an OptionEvent object to all registered listeners. This includes the target NotifyOption, a command (NotifyOption passes the long option by default), and the option value.
