creationCallback
property
public var creationCallback:Function
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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
property
public var discard:Boolean = false
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.
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.

format
property
format:TextFormat
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.
Implementation public function get format():TextFormat public function set format(value:TextFormat):void
hide
property
public var hide:Boolean = true
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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
property
insertPosition:int [write-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
The position of the instance in the parent's child list.
Implementation public function set insertPosition(value:int):void
instances
property
instances:Array [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.
Implementation public function get instances():Array
properties
property
properties:Object
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.
Implementation public function get properties():Object public function set properties(value:Object):void
remove
property
public var remove:Boolean = false
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.

Parameters
type:Object — The type of object to construct.
