A reference to the class object or constructor function for a given object instance. | Object | |

Constructor. | NumberInterpolator | ||
Given a base value and a value to subtract from it,
return the result of that decrement operation. | NumberInterpolator | ||
[static]
Returns the singleton of this class. | NumberInterpolator | ||
|
Indicates whether an object has a specified property defined. | Object | |
Given a base value and a value to add to it,
return the result of that operation. | NumberInterpolator | ||
Interpolation for NumberInterpolator consists of a simple
parametric calculation between startValue and
endValue, using fraction as the
fraction of the elapsed time from start to end:
return startValue + fraction (endValue - startValue);
| NumberInterpolator | ||
|
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | |
|
Indicates whether the specified property exists and is enumerable. | Object | |
|
Sets the availability of a dynamic property for loop operations. | Object | |
|
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | |
|
Returns the string representation of the specified object. | Object | |
|
Returns the primitive value of the specified object. | Object | |
NumberInterpolator | () | Constructor |
public function NumberInterpolator()| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor.
decrement | () | method |
public function decrement(baseValue:Object, decrementValue:Object):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Given a base value and a value to subtract from it,
return the result of that decrement operation. For example,
if the objects are simple Numbers, the result would be
Number(baseValue) - Number(incrementValue).
This function is called by the animation system when it
needs to dynamically calculate a value given some ending
value and a 'by' value that should be subtracted from it. Both of
the arguments are of type Object and cannot simply be added together.
Parameters
baseValue:Object — The start value of the interpolation.
| |
decrementValue:Object — The change to apply to the baseValue.
|
Object — The interpolated value.
|
getInstance | () | method |
public static function getInstance():NumberInterpolator| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns the singleton of this class. Since all NumberInterpolators have the same behavior, there is no need for more than one instance.
ReturnsNumberInterpolator — The singleton of this class.
|
increment | () | method |
public function increment(baseValue:Object, incrementValue:Object):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Given a base value and a value to add to it,
return the result of that operation.
For example, if the objects are simple Numbers, the result is a
Number(baseValue) + Number(incrementValue).
This method is called by the animation system when it
needs to dynamically calculate a value given some starting
value and a 'by' value that should be added to it. Both of
the arguments are of type Object and cannot simply be added together.
Parameters
baseValue:Object — The start value of the interpolation.
| |
incrementValue:Object — The change to apply to the baseValue.
|
Object — The interpolated value.
|
interpolate | () | method |
public function interpolate(fraction:Number, startValue:Object, endValue:Object):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Interpolation for NumberInterpolator consists of a simple
parametric calculation between startValue and
endValue, using fraction as the
fraction of the elapsed time from start to end:
return startValue + fraction (endValue - startValue);
Parameters
fraction:Number — The fraction elapsed of the
animation, between 0.0 and 1.0.
| |
startValue:Object — The start value of the interpolation.
| |
endValue:Object — The end value of the interpolation.
|
Object — The interpolated value.
