| Starting with Flex 4.0, Apache recommends that you use the spark.effects.easing.Power 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 Cubic for the earlier Flex 3 effects. To achieve the same functionality of Cubic, create a Power instance with an `exponent` of 3 and set the `easeInFraction` appropriately to get the desired result.

The Cubic class defines three easing functions to implement motion with Flex effect classes. The acceleration of motion for a Cubic easing equation is greater than for a Quadratic easing equation. For more information, see http://www.robertpenner.com/profmx.

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. | Cubic
|  | 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, accelerates motion, then decelerates back to a zero velocity. | Cubic
|  | 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. | Cubic

Method Detail

easeIn | () | method

`public static function easeIn(t:Number, b:Number, c:Number, d:Number):Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The `easeIn()` method starts motion from zero velocity, and then accelerates motion as it executes.

Parameters

| `t:Number` — Specifies time.
| `b:Number` — Specifies the initial position of a component.
| `c:Number` — Specifies the total change in position of the component.
| `d:Number` — Specifies the duration of the effect, in milliseconds.

Returns

| `Number` — Number corresponding to the position of the component.

easeInOut | () | method |

`public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The `easeInOut()` method combines the motion of the `easeIn()` and `easeOut()` methods to start the motion from zero velocity, accelerates motion, then decelerates back to a zero velocity.

Parameters

| `t:Number` — Specifies time.
| `b:Number` — Specifies the initial position of a component.
| `c:Number` — Specifies the total change in position of the component.
| `d:Number` — Specifies the duration of the effect, in milliseconds.

Returns

| `Number` — Number corresponding to the position of the component.

easeOut | () | method |

`public static function easeOut(t:Number, b:Number, c:Number, d:Number):Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The `easeOut()` method starts motion fast, and then decelerates motion to a zero velocity as it executes.

Parameters

| `t:Number` — Specifies time.
| `b:Number` — Specifies the initial position of a component.
| `c:Number` — Specifies the total change in position of the component.
| `d:Number` — Specifies the duration of the effect, in milliseconds.

Returns

| `Number` — Number corresponding to the position of the component.
