方法詳細資訊

createUpdateEvent

()

方法

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

語言版本:

ActionScript 3.0

產品版本:

Adobe Digital Enterprise Platform Data Services for Java EE 3

執行階段版本:

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.

參數

	`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.

傳回值

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

getDestination

()

方法

public static function getDestination(obj:Object):String

語言版本:

ActionScript 3.0

產品版本:

Adobe Digital Enterprise Platform Data Services for Java EE 3

執行階段版本:

Flash Player 9, AIR 1.1

Returns the destination the specified object is associated with.

參數

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

傳回值

String — String containing the name of the associated destination.

getProperty

()

方法

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

語言版本:

ActionScript 3.0

產品版本:

Adobe Digital Enterprise Platform Data Services for Java EE 3

執行階段版本:

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.

參數

	`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.

傳回值

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

語言版本:

ActionScript 3.0

產品版本:

Adobe Digital Enterprise Platform Data Services for Java EE 3

執行階段版本:

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.

參數

	`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`.
