The Effect class is an abstract base class that defines the basic functionality of all Flex effects. The Effect class defines the base factory class for all effects. The EffectInstance class defines the base class for all effect instance subclasses.

You do not create an instance of the Effect class itself in an application. Instead, you create an instance of one of the subclasses, such as Fade or WipeLeft.

MXML SyntaxexpandedHide MXML Syntax

The Effect class defines the following properties, which all of its subclasses inherit:

  <mx:tagname
    Properties
    customFilter=""
    duration="500"
    filter=""
    hideFocusRing="false"
    perElementOffset="0"
    repeatCount="1"
    repeatDelay="0"
    startDelay="0"
    suspendBackgroundProcessing="false|true"
    target="effect target"
    targets="array of effect targets"
     
    Events
    effectEnd="No default"
    efectStart="No default"
  />

Determines whether the effect should hide the focus ring when starting the effect.
Effect
  instanceClass : Class
An object of type Class that specifies the effect instance class class for this effect class.
Effect

Effect
Protected Properties
 PropertyDefined By
  applyTransitionEndProperties : Boolean
This flag controls whether the effect, when run in a transition, automatically applies the property values according to the end state, as opposed to leaving values as set by the effect itself.
Effect
  endValuesCaptured : Boolean = false
A flag containing true if the end values of an effect have already been determined, or false if they should be acquired from the current properties of the effect targets when the effect runs.

Effect
  
Creates a single effect instance and initializes it.
Effect
  
createInstances(targets:Array = null):Array
Takes an Array of target objects and invokes the createInstance() method on each target.
Effect
  
Removes event listeners from an instance and removes it from the list of instances.

EventDispatcher
  
end(effectInstance:IEffectInstance = null):void

Effect
 Inherited
Sets the availability of a dynamic property for loop operations.
Object
