Sine

Package	spark.effects.easing
Class	public class Sine
Inheritance	Sine EaseInOutBase Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The Sine class defines easing functionality using a Sine function. Easing consists of two phases: the acceleration, or ease in phase, followed by the deceleration, or ease out phase. Use the easeInFraction property to specify the percentage of an animation accelerating.

Public Properties

	Property		Defined By
		constructor : Object A reference to the class object or constructor function for a given object instance.	Object
		easeInFraction : Number The percentage of an animation that should be spent accelerating.	EaseInOutBase

Public Methods

	Method		Defined By
		Sine(easeInFraction:Number = 0.5) Constructor.	Sine
		ease(fraction:Number):Number Takes the fraction representing the elapsed duration of an animation (a value between 0.0 to 1.0) and returns a new elapsed value.	EaseInOutBase
		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

Protected Methods

	Method		Defined By
		easeIn(fraction:Number):Number Returns a value that represents the eased fraction during the ease in phase of the animation.	EaseInOutBase
		easeOut(fraction:Number):Number Returns a value that represents the eased fraction during the ease out phase of the animation.	EaseInOutBase

()

Constructor

public function Sine(easeInFraction:Number = 0.5)

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Constructor.

Parameters

easeInFraction:Number (default = 0.5) — Sets the value of the easeInFraction property. The default value is EasingFraction.IN_OUT, which eases in for the first half of the time and eases out for the remainder.
