easeInFraction | property |
easeInFraction:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The percentage of an animation that should be spent accelerating.
This factor sets an implicit
"easeOut" parameter, equal to (1 - easeIn), so that any time not
spent easing in is spent easing out. For example, to have an easing
equation that spends half the time easing in and half easing out,
set easeIn to .5.
Valid values are between 0.0 and 1.0.
The default value is .5.
Implementation
public function get easeInFraction():Number public function set easeInFraction(value:Number):voidEaseInOutBase | () | Constructor |
public function EaseInOutBase(easeInFraction:Number = NaN)| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor.
ParameterseaseInFraction:Number (default = NaN)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.

ease | () | method |
public function ease(fraction:Number):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Takes the fraction representing the elapsed duration of an animation
(a value between 0.0 to 1.0) and returns a new elapsed value.
This value is used to calculate animated property values.
By changing the value of the elapsed fraction, you effectively change
the animation of the property.
For EaseInOutBase, this method calculates the eased fraction
value based on the easeInFraction property. If
fraction is less than easeInFraction,
this method calls the easeIn() method. Otherwise it
calls the easeOut() method.
It is expected
that these functions are overridden in a subclass.
Parameters
fraction:Number — The elapsed fraction of the animation.
|
Number — The eased fraction of the animation.
|
easeIn | () | method |
protected function easeIn(fraction:Number):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns a value that represents the eased fraction during the ease in phase of the animation. The value returned by this class is simply the fraction itself, which represents a linear interpolation of the fraction. More interesting behavior is implemented by subclasses of EaseInOutBase.
Parameters
fraction:Number — The fraction elapsed of the easing in phase
of the animation, between 0.0 and 1.0.
|
Number — A value that represents the eased value for this
phase of the animation.
|
easeOut | () | method |
protected function easeOut(fraction:Number):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns a value that represents the eased fraction during the ease out phase of the animation. The value returned by this class is simply the fraction itself, which represents a linear interpolation of the fraction. More interesting behavior is implemented by subclasses of EaseInOutBase.
Parameters
fraction:Number — The fraction elapsed of the easing out phase
of the animation, between 0.0 and 1.0.
|
Number — A value that represents the eased value for this
phase of the animation.
