Classpublic class XMLNotifier
InheritanceXMLNotifier Inheritance 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.
