Descrizione delle proprietà

creationPolicy

proprietà

creationPolicy:String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The creation policy for the items. This property determines when the itemsFactory will create the instance of the items. Flex uses this property only if you specify an itemsFactory property. The following values are valid:

Value	Meaning
`auto`	(default)Create the instance the first time it is needed.
`all`	Create the instance when the application started up.
`none`	Do not automatically create the instance. You must call the `createInstance()` method to create the instance.

Il valore predefinito è "auto".

Implementazione
public function get creationPolicy():String
public function set creationPolicy(value:String):void

destination

proprietà

public var destination:Object

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The object relative to which the child is added. This property is used in conjunction with the position property. This property is optional; if you omit it, Flex uses the immediate parent of the State object, that is, the component that has the states property, or <mx:states>tag that specifies the State object.

destructionPolicy

proprietà

destructionPolicy:String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The destruction policy for the items. This property determines when the itemsFactory will destroy the deferred instances it manages. By default once instantiated, all instances are cached (destruction policy of 'never'). Flex uses this property only if you specify an itemsFactory property. The following values are valid:

Value	Meaning
`never`	(default)Once created never destroy the instance.
`auto`	Destroy the instance when the override no longer applies.

Il valore predefinito è "never".

Implementazione
public function get destructionPolicy():String
public function set destructionPolicy(value:String):void

isArray

proprietà

public var isArray:Boolean = false

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Denotes whether or not the collection represented by the target property is to be treated as a single array instance instead of a collection of items (the default).

Il valore predefinito è false.

isStyle

proprietà

public var isStyle:Boolean = false

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Denotes whether or not the collection represented by the target property is a style.

Il valore predefinito è false.

items

proprietà

items:*

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The items to be added. If you set this property, the items are created at app startup. Setting this property is equivalent to setting a itemsFactory property with a creationPolicy of "all".

Do not set this property if you set the itemsFactory property.

Implementazione
public function get items():*
public function set items(value:any):void

itemsFactory

proprietà

itemsFactory:mx.core:ITransientDeferredInstance

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The factory that creates the items.

If you set this property, the items are instantiated at the time determined by the creationPolicy property.

Do not set this property if you set the items property. This propety is the AddItems class default property. Setting this property with a creationPolicy of "all" is equivalent to setting a items property.

Implementazione
public function get itemsFactory():mx.core:ITransientDeferredInstance
public function set itemsFactory(value:mx.core:ITransientDeferredInstance):void

position

proprietà

public var position:String = "last"

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The position of the child in the display list, relative to the object specified by the relativeTo property.

Il valore predefinito è AddItems.LAST.

propertyName

proprietà

public var propertyName:String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The name of the Array property that is being modified. If the destination property is a Group or Container, this property is optional. If not defined, the items will be added as children of the Group/Container.

relativeTo

proprietà

public var relativeTo:Object

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

The object relative to which the child is added. This property is only used when the position property is AddItems.BEFORE or AddItems.AFTER.

vectorClass

proprietà

public var vectorClass:Class

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni runtime:

Flash Player 10, AIR 1.5

When the collection represented by the target property is a Vector, vectorClass is the type of the target. It is used to initialize the target property.

Descrizione della funzione di costruzione

()

Funzione di costruzione

public function AddItems()

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Constructor.

Descrizione dei metodi

apply

()

metodo

override public function apply(parent:UIComponent):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Applies the override. Flex retains the original value, so that it can restore the value later in the remove() method.

This method is called automatically when the state is entered. It should not be called directly.

Parametri

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.

createInstance

()

metodo

public function createInstance():void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Creates the items instance from the factory. You must use this method only if you specify a targetItems property and a creationPolicy value of "none". Flex automatically calls this method if the creationPolicy property value is "auto" or "all". If you call this method multiple times, the items instance is created only on the first call.

initialize

()

metodo

override public function initialize():void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

IOverride interface method; this class implements it as an empty method.

remove

()

metodo

override public function remove(parent:UIComponent):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Removes the override. The value remembered in the apply() method is restored.

This method is called automatically when the state is entered. It should not be called directly.

Parametri

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.
