XMLNotifier

Package | mx.utils
Class | public class XMLNotifier
Inheritance | XMLNotifier Object

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Used for watching changes to XML and XMLList objects. Those objects are not EventDispatchers, so if multiple elements want to watch for changes they need to go through this mechanism. Call `watchXML()`, passing in the same notification function that you would pass to XML.notification. Use `unwatchXML()` to remove that notification.
