InstanceCache(type:Object, parent:Object = null, insertPosition:int = -1, moduleFactory:IFlexModuleFactory = null)
Constructor. | InstanceCache | ||
Geeft aan of voor een object een opgegeven eigenschap is gedefinieerd. | Object | ||
Geeft aan of een instantie van de klasse Object zich in de prototypeketen van het object bevindt dat als parameter is opgegeven. | Object | ||
Geeft aan of de opgegeven eigenschap bestaat en kan worden opgesomd. | Object | ||

creationCallback | eigenschap |
public var creationCallback:Function
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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 | eigenschap |
public var discard:Boolean = false
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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 | eigenschap |
factory:IFactory
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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.
Implementatie
public function get factory():IFactory
public function set factory(value:IFactory):void
format | eigenschap |
format:flash.text:TextFormat
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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.
Implementatie
public function get format():flash.text:TextFormat
public function set format(value:flash.text:TextFormat):void
hide | eigenschap |
public var hide:Boolean = true
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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 | eigenschap |
instances | eigenschap |
instances:Array
[alleen-lezen] Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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.
Implementatie
public function get instances():Array
properties | eigenschap |
properties:Object
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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.
Implementatie
public function get properties():Object
public function set properties(value:Object):void
remove | eigenschap |
public var remove:Boolean = false
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | 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 | () | Constructor |
public function InstanceCache(type:Object, parent:Object = null, insertPosition:int = -1, moduleFactory:IFlexModuleFactory = null)
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
Constructor.
Parameterstype: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.
