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):void| hideFocusRing | 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

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):void| propertyChanges | 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.

| 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

      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.

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.

| 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):void| EffectInstance | () | 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. | 
| pause | () | method | 
 public function pause():void| Language Version: | ActionScript 3.0 | 
| Product Version: | Flex 3 | 
| Runtime Versions: | Flash Player 9, AIR 1.1 | 
      Pauses the effect until you call the resume() method.
      
      
| 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.
