Documentation for classes includes syntax, usage information, and code samples for methods, properties, and event handlers and listeners for those APIs that belong to a specific class in ActionScript. The classes are listed alphabetically. If you are not sure to which class a certain method or property belongs, you can look it up in the Index.

	Class	Package	Description
	AlignMode	com.greensock.layout	Provides constants for defining the alignment of objects.
	AutoAlphaPlugin	com.greensock.plugins	Tweening "autoAlpha" is exactly the same as tweening an object's "alpha" except that it ensures that the object's "visible" property is true until autoAlpha reaches zero at which point it will toggle the "visible" property to false.
	AutoFitArea	com.greensock.layout	AutoFitArea allows you to define a rectangular area and then attach() DisplayObjects so that they automatically fill the area, scaling/stretching in any of the following modes: STRETCH, PROPORTIONAL_INSIDE, PROPORTIONAL_OUTSIDE, NONE, WIDTH_ONLY, or HEIGHT_ONLY.
	Back	com.greensock.easing
	BevelFilterPlugin	com.greensock.plugins	Tweens a BevelFilter.
	BevelFilterVars	com.greensock.data
	BezierPlugin	com.greensock.plugins	Bezier tweening allows you to tween in a non-linear way.
	BezierThroughPlugin	com.greensock.plugins	Identical to bezier except that instead of defining bezier control point values, you define points through which the bezier values should move.

	BlurFilterVars	com.greensock.data
	Bounce	com.greensock.easing
	CacheAsBitmapPlugin	com.greensock.plugins	Forces the cacheAsBitmap property of a DisplayObject to be a certain value (true or false) during the tween and then sets it back to whatever it was before the tween was rendered for the first time.
	Circ	com.greensock.easing
	CirclePath2D	com.greensock.motionPaths	A CirclePath2D defines a circular path on which a PathFollower can be placed, making it simple to tween objects along a circle or oval (make an oval by altering the width/height/scaleX/scaleY properties).
	CirclePath2DPlugin	com.greensock.plugins	Tweens an object along a CirclePath2D motion path in any direction (clockwise, counter-clockwise, or shortest).

	DynamicPinPoint	com.greensock.layout	Sometimes it's useful to have a PinPoint base its coordinates on some custom criteria, like the edge of another DisplayObject or the center of an object whose width/height changes frequently, so DynamicPinPoint allows you to associate a function (one you define) that returns a Point instance that will determine the DynamicPinPoint's x/y values.
	DynamicPropsPlugin	com.greensock.plugins	If you'd like to tween something to a destination value that may change at any time, DynamicPropsPlugin allows you to simply associate a function with a property so that every time the tween is rendered, it calls that function to get the new destination value for the associated property.
	EaseLookup	com.greensock.easing	EaseLookup enables you to find the easing function associated with a particular name (String), like "strongEaseOut" which can be useful when loading in XML data that comes in as Strings but needs to be translated to native function references.

	LiquidArea	com.greensock.layout	LiquidArea is an AutoFitArea that integrates with LiquidStage, automatically adjusting its size whenever the stage is resized.
	LiquidData	com.greensock.layout.core	LiquidData holds core information about PinPoints and DisplayObjects that have been attached to a LiquidStage, but this class is only intended to be used by LiquidStage internally - there is no reason to use it directly.
	LiquidPositionPlugin	com.greensock.plugins	If you're using LiquidStage and you'd like to tween a DisplayObject to coordinates that are relative to a particular PinPoint (like the CENTER) whose position may change at any time, LiquidPositionPlugin makes it easy by dynamically updating the destination values accordingly.
	LiquidStage	com.greensock.layout	LiquidStage allows you to "pin" DisplayObjects to reference points on the stage (or inside other DisplayObjects) so that when the stage is resized, they are repositioned and maintain their relative distance from the PinPoint.

	TintPlugin	com.greensock.plugins	To change a DisplayObject's tint/color, set this to the hex value of the tint you'd like to end up at (or begin at if you're using TweenMax.from()).
	TransformAroundCenterPlugin	com.greensock.plugins	Normally, all transformations (scale, rotation, and position) are based on the DisplayObject's registration point (most often its upper left corner), but TransformAroundCenter allows you to make the transformations occur around the DisplayObject's center.

USAGE: Instead of TweenLite.to(mc, 1, {x:300, tint:0xFF0000, onComplete:myFunction}), you could use this utility like: var myVars:TweenLiteVars = new TweenLiteVars(); myVars.addProp("x", 300); // use addProp() to add any property that doesn't already exist in the TweenLiteVars instance. myVars.tint = 0xFF0000; myVars.onComplete = myFunction; TweenLite.to(mc, 1, myVars); NOTES: This class adds about 13 Kb to your published SWF (including all dependencies). This utility is completely optional.
	TweenMax	com.greensock	TweenMax extends the extremely lightweight, fast TweenLite engine, adding many useful features like timeScale, event dispatching, updateTo(), yoyo, repeat, repeatDelay, rounding, and more.
	TweenMaxVars	com.greensock.data	There are 2 primary benefits of using this utility to define your TweenMax variables: In most code editors, code hinting will be activated which helps remind you which special properties are available in TweenMax It allows you to code using strict datatyping (although it doesn't force you to).
	TweenNano	com.greensock	TweenNano is a super-lightweight (1.6k in AS3 and 2k in AS2) version of TweenLite and is only recommended for situations where you absolutely cannot afford the extra 3.1k (4.7k total) that the normal TweenLite engine would cost and your project doesn't require any plugins.
	TweenPlugin	com.greensock.plugins	TweenPlugin is the base class for all TweenLite/TweenMax plugins.
	TweenProxy	com.greensock	TweenProxy essentially "stands in" for a DisplayObject, adding several tweenable properties as well as the ability to set a custom registration point around which all transformations (like rotation, scale, and skew) occur.
	VarsCore	com.greensock.data	VarsCore provides a way to make an object's non-dynamic properties enumerable (only if/when the property is set to a non-default value) which is necessary for many of the vars objects in the GreenSock tweening platform (TweenLiteVars, TweenMaxVars, etc.).
	VideoEvent	com.greensock.events
	VideoLoader	com.greensock.loading	Loads an FLV, F4V, or MP4 video file using a NetStream and also provides convenient playback methods and properties like pauseVideo(), playVideo(), gotoVideoTime(), bufferProgress, playProgress, volume, duration, videoPaused, metaData, and videoTime.
