creationCallback | egenskap |
public var creationCallback:Function
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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 | egenskap |
public var discard:Boolean = false
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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 | egenskap |
factory:IFactory
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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.
Implementering
public function get factory():IFactory
public function set factory(value:IFactory):void
format | egenskap |
format:flash.text:TextFormat
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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.
Implementering
public function get format():flash.text:TextFormat
public function set format(value:flash.text:TextFormat):void
hide | egenskap |
public var hide:Boolean = true
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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 | egenskap |
instances | egenskap |
instances:Array
[skrivskyddad] Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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.
Implementering
public function get instances():Array
properties | egenskap |
properties:Object
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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.
Implementering
public function get properties():Object
public function set properties(value:Object):void
remove | egenskap |
public var remove:Boolean = false
Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | 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.
InstanceCache | () | Konstruktor |
public function InstanceCache(type:Object, parent:Object = null, insertPosition:int = -1, moduleFactory:IFlexModuleFactory = null)

Constructor.
Parametrartype:Object — The type of object to construct.
This can be either a Class or an IFactory.
| |
parent:Object (default = null ) — An optional DisplayObject to add new instances to.
| |
insertPosition:int (default = -1 ) — Where in the parent's child list
to insert instances. Set to -1 to add the children to the end of the child list.
| |
moduleFactory:IFlexModuleFactory (default = null ) — The context for using embedded fonts and for
finding the style manager that controls the styles for this component.
