	Metodo		Definito da
		addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void Registra un oggetto listener di eventi con un oggetto EventDispatcher, in modo che il listener riceva la notifica di un evento.	IEventDispatcher
		dispatchEvent(event:Event):Boolean Invia un evento nel flusso di eventi.	IEventDispatcher
		evaluateExpression(expression:String, expressionDefinitionId:String, varsMap:Object, qualifiedClassName:String):Object This API is used to evaluate an expression at flex side.	IExpressionEvaluationService
		hasEventListener(type:String):Boolean Verifica se per l'oggetto EventDispatcher sono presenti listener registrati per un tipo specifico di evento.	IEventDispatcher
		registerExpressionsUsingBytesLoader(expressionDefinitionId:String, swfBytes:ByteArray, lazyLoad:Boolean = false):void This API is used to load swf from the specified byte array.	IExpressionEvaluationService
		registerExpressionsUsingLoader(expressionDefinitionId:String, expressionLoader:IExpressionLoader, lazyLoad:Boolean = false):void This API is used to load swf using a custom loader.	IExpressionEvaluationService
		registerExpressionsUsingUrlLoader(expressionDefinitionId:String, swfUrl:String, urlVars:Object = null, lazyLoad:Boolean = false):void This API is used to load the expression swf from the specified URL.	IExpressionEvaluationService
		removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void Rimuove un listener dall'oggetto EventDispatcher.	IEventDispatcher
		willTrigger(type:String):Boolean Verifica se un listener di eventi è registrato con questo oggetto EventDispatcher o qualsiasi suo antenato per il tipo di evento specificato.	IEventDispatcher

Descrizione dei metodi

Descrizione degli eventi

Note legali | Informativa sulla privacy online

	`expression:String` — expression to be evaluated.

	`expressionDefinitionId:String` — unique id used to load the expression swf into flex application.

	`varsMap:Object` — map containing variables used in expressions.

	`qualifiedClassName:String` — Name of the AS class containing expressions. This name is passed to the generateSWF API at the time of generating swf.

	`expressionDefinitionId:String` — unique id used later for evaluating expressions contained in this swf.

	`swfUrl:String` — url of the swf.

	`urlVars:Object` (default = `null`) — url variables

	`lazyLoad:Boolean` (default = `false`) — if true swf will be loaded on first expression evaluation.

	`expressionDefinitionId:String` — unique id used later for evaluating expressions contained in this swf.

	`swfBytes:ByteArray` — byte[] containing swf.

	`lazyLoad:Boolean` (default = `false`) — if true swf will be loaded on first expression evaluation.

	`expressionDefinitionId:String` — unique id used later for evaluating expressions contained in this swf.

	`expressionLoader:IExpressionLoader` — custom expression loader for loading swf.

	`lazyLoad:Boolean` (default = `false`) — if true swf will be loaded on first expression evaluation. The default value is `false`.
