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

(Preview)

Package	mx.effects.easing
Class	public class Sine
Inheritance	Sine 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.Sine 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 Sine for the earlier Flex 3 effects. To achieve the same functionality of the old Sine class, create a spark.effects.Sine instance with an appropriate easeInFraction to get the desired result.

The Sine class defines three easing functions to implement motion with Flex effect classes, where the motion is defined by a sine wave. For more information, see http://www.robertpenner.com/profmx.

	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.	Sine
		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 a zero velocity, accelerate motion, then decelerate to a zero velocity.	Sine
		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.	Sine
		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
