createUpdateEvent

()

método

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

Versión del lenguaje:

ActionScript 3.0

Versión de producto:

Adobe Digital Enterprise Platform Data Services for Java EE 3

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.

Parámetros

	`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.

Valor devuelto

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

getDestination

()

método

public static function getDestination(obj:Object):String

Versión del lenguaje:

ActionScript 3.0

Versión de producto:

Returns the destination the specified object is associated with.

Parámetros

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

Valor devuelto

String — String containing the name of the associated destination.

getProperty

()

método

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

Versión del lenguaje:

ActionScript 3.0

Versión de producto:

Adobe Digital Enterprise Platform Data Services for Java EE 3

Versiones de motor de ejecución:

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.

Parámetros

	`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.

Valor devuelto

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