className | property |
className:String [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The name of the effect class, such as "FadeInstance".
This is a short or "unqualified" class name
that does not include the package name.
If you need the qualified name, use the
getQualifiedClassName() method
in the flash.utils package.
Implementation

effect | property |
effectTargetHost | property |
effectTargetHost:mx.effects:IEffectTargetHost| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A property that lets you access the target list-based control of a data effect. This property enables an instance of an effect class to communicate with the list-based control on which the effect is playing.
Implementation
public function get effectTargetHost():mx.effects:IEffectTargetHost public function set effectTargetHost(value:mx.effects:IEffectTargetHost):voidhideFocusRing | property |
hideFocusRing:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Determines whether the effect should hide the focus ring when starting the effect. The effect target is responsible for the hiding the focus ring. Subclasses of the UIComponent class hide the focus ring automatically. If the effect target is not a subclass of the UIComponent class, you must add functionality to it to hide the focus ring.
Set this property to true
to hide the focus ring during the effect.
For subclasses of Effect, the default value is false.
For subclasses of MaskEffect, the default value is true.
Implementation
public function get hideFocusRing():Boolean public function set hideFocusRing(value:Boolean):voidplayCount | property |
protected var playCount:int = 0| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number of times that the instance has been played.
playheadTime | property |
playheadTime:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Current time position of the effect.
This property has a value between 0 and the total duration,
which includes the Effect's startDelay,
repeatCount, and repeatDelay.
Implementation
public function get playheadTime():Number public function set playheadTime(value:Number):voidpropertyChanges | property |
propertyChanges:PropertyChanges| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies the PropertyChanges object containing
the start and end values for the set of properties
relevant to the effect's targets.
This property is only set if the
captureStartValues() method was called
on the effect that created this effect instance.
You often use the propertyChanges property
to create an effect that is used as part of a transition.
Flex automatically calls the captureStartValues()
method when it starts a transition.
Within your override of the Effectinstance.play()
method, you can examine the information within the
propertyChanges() method to initialize
the start and end values of the effect.
Implementation

repeatCount | property |
repeatCount:int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number of times to repeat the effect. Possible values are any integer greater than or equal to 0.
Implementation
public function get repeatCount():int public function set repeatCount(value:int):voidrepeatDelay | property |
startDelay | property |
startDelay:int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Amount of time, in milliseconds,
to wait before starting the effect.
Possible values are any int greater than or equal to 0.
If the effect is repeated by using the repeatCount
property, the startDelay property is applied
only the first time the effect is played.
Implementation
public function get startDelay():int public function set startDelay(value:int):voidsuspendBackgroundProcessing | property |
suspendBackgroundProcessing:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
If true, blocks all background processing
while the effect is playing.
Background processing includes measurement, layout,
and processing responses that have arrived from the server.
Implementation
public function get suspendBackgroundProcessing():Boolean public function set suspendBackgroundProcessing(value:Boolean):voidtarget | property |
triggerEvent | property |
triggerEvent:Event| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The event, if any, which triggered the playing of the effect. This property is useful when an effect is assigned to multiple triggering events.
If the effect was played programmatically by a call to the
play() method, rather than being triggered by an event,
this property is null.
Implementation
public function get triggerEvent():Event public function set triggerEvent(value:Event):voidEffectInstance | () | Constructor |
end | () | method |
public function end():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Interrupts an effect instance that is currently playing,
and jumps immediately to the end of the effect.
This method is invoked by a call
to the Effect.end() method.
As part of its implementation, it calls
the finishEffect() method.
The effect instance dispatches an effectEnd event
when you call this method as part of ending the effect.
In a subclass of EffectInstance,
you can optionally override this method
As part of your override, you should call
the super.end() method
from the end of your override, after your logic.
More examples
finishEffect | () | method |
public function finishEffect():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Called by the end() method when the effect
finishes playing.
This function dispatches an endEffect event
for the effect target.
You do not have to override this method in a subclass. You do not need to call this method when using effects, but you may need to call it if you create an effect subclass.
finishRepeat | () | method |
public function finishRepeat():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Called after each iteration of a repeated effect finishes playing.
You do not have to override this method in a subclass. You do not need to call this method when using effects.
initEffect | () | method |
public function initEffect(event:Event):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
This method is called if the effect was triggered by the EffectManager.
This base class version saves the event that triggered the effect
in the triggerEvent property.
Each subclass should override this method.
Parameters
event:Event — The Event object that was dispatched
to trigger the effect.
For example, if the trigger was a mouseDownEffect, the event
would be a MouseEvent with type equal to MouseEvent.MOUSEDOWN.

play | () | method |
public function play():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Plays the effect instance on the target.
Call the startEffect() method instead
to make an effect start playing on an EffectInstance.
In a subclass of EffectInstance, you must override this method.
The override must call the super.play() method
so that an effectStart event is dispatched
from the target.

startDelay period has elapsed.
Called by the Effect class.
Use this function instead of the play() method
when starting an EffectInstance.
stop | () | method |
public function stop():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
