creationCallback | 屬性 |
public var creationCallback:Function| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
A callback invoked when new instances are created. This callback has the following signature:
function creationCallback(newInstance:Object, cache:InstanceCache):void;
discard | 屬性 |
public var discard:Boolean = false| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Determines if unneeded instances are discarded.
If set to true, extra elements are discarded
when the cache count is reduced.
Otherwise, extra elements are kept in a separate cache
and reused when the count is increased.
factory | 屬性 |
factory:IFactory| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
A factory that generates the type of object to cache. Assigning to this discards all current instances and recreate new instances of the correct type.
實作
public function get factory():IFactory public function set factory(value:IFactory):voidformat | 屬性 |
format:flash.text:TextFormat| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
A TextFormat to apply to any instances created. If set, this format is applied as the current and default format for the contents of any instances created. This property is only relevant if the factory generates TextField instances.
實作
public function get format():flash.text:TextFormat public function set format(value:flash.text:TextFormat):voidhide | 屬性 |
public var hide:Boolean = true| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Determines if unneeded instances should be hidden.
If true, the visible property
is set to false on each extra element
when the cache count is reduced, and set to true
when the count is increased.
This property is only relevant when the factory
generates DisplayObjects.
Setting this property to true for other factory types
generates a run-time error.
insertPosition | 屬性 |
instances | 屬性 |
instances:Array [唯讀] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The Array of cached instances.
There may be more instances in this Array than currently requested.
You should rely on the count property
of the instance cache rather than the length of this Array.
實作
public function get instances():Arrayproperties | 屬性 |
properties:Object| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
A hashmap of properties to assign to new instances. Each key/value pair in this hashmap is assigned to each new instance created. The property hashmap is assigned to any existing instances when set.
The values in the hashmap are not cloned; object values are shared by all instances.
實作
public function get properties():Object public function set properties(value:Object):voidremove | 屬性 |
public var remove:Boolean = false| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Determines if unneeded instances should be removed from their parent.
If true, the removeChild() method
is called on the parent for each extra element
when the cache count is reduced.
This property is only relevant when the factory
generates DisplayObjects.
Setting this property to true for other factory types
generates a run-time error.
