public class DoubleKeyFrameCollection extends Freezable implements IList, ICollection, IEnumerable
<DoubleKeyFrameCollection .../>
<object> <object.property> oneOrMoreDoubleKeyFrameObjectElements </object.property> </object>
oneOrMoreDoubleKeyFrameObjectElements One or more DoubleKeyFrame objects, declared using object element syntax.
This collection is used as part of a DoubleAnimationUsingKeyFrames to animate a Double property value along a set of key frames.
The following example demonstrates how to use a DoubleAnimationUsingKeyFrames animation.
