If true, the effect retains its target during a transition and removes it when finished. This capability applies specifically to effects like Fade which act on targets that go away at the end of the transition and removes the need to supply a RemoveAction or similar effect to manually keep the item around and remove it when the transition completes.

To use this capability, subclasses should set this variable to true and also expose the parent property in their affectedProperties Array so that the effect instance has enough information about the target and container to do the job.

If true, the effect disables layout on its targets' parent containers, setting the containers autoLayout property to false, and also disables any layout constraints on the target objects. These properties are restored when the effect finishes.

The easing behavior for this effect. This IEaser object is used to convert the elapsed fraction of the animation into an eased fraction, which is then used to calculate the value at that eased elapsed fraction.

Note that it is possible to have easing at both the effect level and the Keyframe level (where Keyframes hold the values/times used in the MotionPath structures). These easing behaviors build on each other. The easer controls the easing of the overall effect. The Keyframe controls the easing in any particular interval of the animation. By default, the easing for Animate is non-linear (Sine(.5)). The easing for Keyframes is linear. If you desire an effect with easing at the keyframe level instead, you can set the easing of the effect to linear, and then set the easing specifically on the Keyframes.

The interpolator used by this effect to calculate values between the start and end values of a property. By default, the NumberInterpolator class handles interpolation or, in the case of the start and end values being Arrays or Vectors, by the MultiValueInterpolator class. Interpolation of other types, or of Numbers that should be interpolated differently, such as uint values that hold color channel information, can be handled by supplying a different interpolator.

A Vector of MotionPath objects, each of which holds the name of a property being animated and the values that the property takes during the animation. This Vector takes precedence over any properties declared in subclasses of Animate. For example, if this Array is set directly on a Move effect, then any properties of the Move effect, such as xFrom, are ignored.

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.

The behavior of a repeating effect, which means an effect with repeatCount equal to either 0 or > 1. This value should be either RepeatBehavior.LOOP, which means the animation repeats in the same order each time, or RepeatBehavior.REVERSE, which means the animation reverses direction on each iteration.
