Linear - BETA ActionScript® 3 (AS3 Flex) Reference for the Adobe® Flash® Platform API Reference

(Preview)

Package	mx.effects.easing
Class	public class Linear
Inheritance	Linear Object

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Starting with Flex 4.0, Adobe recommends that you use the spark.effects.easing.Linear class as an alternative to this class.

The Spark effects provided as of Flex 4 use classes which implement the IEaser interface instead of the easing functions in classes like Linear for the earlier Flex 3 effects. To achieve the same functionality of the old Linear class, create a new instance of spark.effects.easing.Linear or call spark.effects.easing.Linear.getInstance() to get a singleton instance.

The Linear class defines easing functions to implement linear motion with Flex effect classes. For more information, see http://www.robertpenner.com/profmx.

Show Inherited Public Methods

	Method		Defined By
		easeIn(t:Number, b:Number, c:Number, d:Number):Number [static] The easeIn() method starts motion from zero velocity, and then accelerates motion as it executes.	Linear
		easeInOut(t:Number, b:Number, c:Number, d:Number):Number [static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion from zero velocity, accelerate motion, then decelerate back to zero velocity.	Linear
		easeNone(t:Number, b:Number, c:Number, d:Number):Number [static] The easeNone() method defines a constant motion, with no acceleration.	Linear
		easeOut(t:Number, b:Number, c:Number, d:Number):Number [static] The easeOut() method starts motion fast, and then decelerates motion to a zero velocity as it executes.	Linear
		hasOwnProperty(name:String):Boolean Indicates whether an object has a specified property defined.	Object
		isPrototypeOf(theClass:Object):Boolean Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.	Object
		propertyIsEnumerable(name:String):Boolean Indicates whether the specified property exists and is enumerable.	Object
		setPropertyIsEnumerable(name:String, isEnum:Boolean = true):void Sets the availability of a dynamic property for loop operations.	Object
		toLocaleString():String Returns the string representation of this object, formatted according to locale-specific conventions.	Object
		toString():String Returns the string representation of the specified object.	Object
		valueOf():Object Returns the primitive value of the specified object.	Object
