Note: In Flash CS3, many of the properties and methods supported by this class were members of this class, exclusively. Flash CS4 introduced a base class, KeyframeBase, for those properties and methods of this class, and they are now shared by other classes through the inheritance chain. If you have been working in Flash CS3, notice that these properties and methods are still supported by the Keyframe class, but are members of the KeyframeBase class in releases of Flash Professional after Flash CS3. As with any other class in this reference, select Show Inherited Public Properties and Show Inherited Public Methods to see all of the properties and methods supported by this class.

keyframesCompact | property |
keyframesCompact:Array| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
A compact array of keyframes, where each index is occupied by a keyframe.
By contrast, a sparse array has empty indices (as in the keyframes property).
In the compact array, no null values are used to fill indices between keyframes.
However, the index of a keyframe in keyframesCompact likely does not match its index in the keyframes array.
This property is primarily used for compatibility with the Flex MXML compiler, which generates a compact array from the motion XML.
