Descrizione dei metodi

createUpdateEvent

()

metodo

public static function createUpdateEvent(obj:IManaged, property:Object, event:PropertyChangeEvent):PropertyChangeEvent

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Creates a new PropertyChangeEvent object from an existing PropertyChangeEvent object. The value of the property property of the new object is the value of the property argument prepended to event.property.

Parametri

	`obj:IManaged` — IManaged reference to the object on which the desired property should be retrieved from.

	`property:Object` — String containing the name of the desired property.

	`event:PropertyChangeEvent` — A PropertyChangeEvent to copy.

Restituisce

PropertyChangeEvent — A new PropertyChangeEvent object with the value of the property argument prepended to event.property.

getDestination

()

metodo

public static function getDestination(obj:Object):String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Returns the destination the specified object is associated with.

Parametri

obj:Object — Object reference to the item to get the destination from.

Restituisce

String — String containing the name of the associated destination.

getProperty

()

metodo

public static function getProperty(obj:IManaged, property:String, value:*, useHierarchicalValues:Boolean = true):*

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

This method is used to retrieve a property from a managed object. In addition to returning the value of the property specified, this method will handle keeping related artifacts in sync to support both deeply nested event dispatching and lazily loaded properties.

Parametri

	`obj:IManaged` — IManaged reference to the object on which the desired property should be retrieved from.

	`property:String` — String containing the name of the desired property.

	`value:*` — any reference to the current value of the property.

	`useHierarchicalValues:Boolean` (default = `true`) — whether a complex (hierarchical) value will be managed.

Restituisce

* — the new normalized value of the property. This value should be assigned to the original reference.

         {
             _addresses = Managed.getProperty(this, "addresses", _addresses);
         }
     
         public function set addresses(value:ArrayCollection):void
         {

()

metodo

public static function propertyFetched(obj:Object, property:String):Boolean

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Returns false if the property on the item specified has not yet been fetched from the server.

Parametri

	`obj:Object` — Object reference to the item to check.

	`property:String` — The property.

Restituisce

Boolean — false if the property on the item specified has not yet been fetched from the server.

setProperty

()

metodo

public static function setProperty(obj:IManaged, property:Object, oldValue:*, newValue:*):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

This method is used to set the property of a managed object. In addition to setting the vlaue of the property specified, this method will handle keeping related artifacts in sync and clean up any deeply nested event dispatching and lazy loaded properties.

Parametri

	`obj:IManaged` — IManaged reference to the managed object that the property will be set on

	`property:Object` — Object containing the name of the property that will be set. Typically this is a `String` value but can be a `QName`.

	`oldValue:*` — reference to the previous value of the property.

	`newValue:*` — reference to the new value of the property
