IntroductionFabrication reduces the switch-case complexity in a Mediator's handleNotification by using reflection. Instead of specifying the notification interests array with handleNotification you write respondTo<NotificationName> methods inside the mediators. RequirementsThis feature uses the Flash Player's reflection api and when using modular applications needs an additional getClassByName method in your application's main class. This method is needed to workaround the sandboxing of getDefinitionByName. The following code must be present along with your getStartupCommand method for reflection to work. override public function getClassByName(path:String):Class {
return getDefinitionByName(path) as Class;
}The respondTo conventionThe respondTo convention assumes that for any method named respondTo<NotificationName> in your mediator, you are interested in the corresponding notificationName PureMVC notification. The convention requires that notification names be lower camel-cased when sending. And upper camel-cased in the respondTo handler function. You can specify n number of respondTo handlers for the notifications that you want to handle in your mediator. Each is treated as an interest in the notification. Some typical respondTo handlers are listed below. Handles the ready notification public function respondToReady(note:INotification):void {
}Handles the available notification public function respondToAvailable(note:INotification):void {
}Using custom notification classesWhen using custom notification classes, you have the added benefit of strong typing the notification argument to the type of your custom notification class. Sends a custom notification sendNotification(new CaptionNotification(CaptionNotification.CAPTION_CHANGED)); For CaptionNotification.CAPTION_CHANGED = "captionChanged" the corresponding respondTo handler is, public function respondToCaptionChanged(note:CaptionNotification):void {

Are custom notifications supported? I can't seem to find a sendNotification() method in the framework that takes an INotification object as its arguments.
