The MultiValueInterpolator class interpolates each element of Arrays or
Vectors of start and end elements separately, using another interpolator
to do the interpolation for each element.
By default, the
interpolation for each element uses the NumberInterpolator class, but you
can construct a MultiValueInterpolator instance with a different interpolator.
The interpolator for each element of the input Array or Vector.
A value of null specifies to use the NumberInterpolator class.
The default value is NumberInterpolator.

Constructor
public function MultiValueInterpolator(elementInterpolator:IInterpolator = null)
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :

Constructor.
Parameters
elementInterpolator:IInterpolator (default = null) — The interpolator for each element
of the Array.
If no interpolator is specified, use the NumberInterpolator class.
Method Detail
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.
Returns
Object — The interpolated value.
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.
Returns
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
Given an elapsed fraction of an animation, between 0.0 and 1.0,
and start and end values to interpolate, return the interpolated value.
Interpolation for MultiValueInterpolator consists of running a separate
interpolation on each element of the startValue and endValue
arrays or vectors, returning a new Array or Vector that holds those
interpolated values. The returned object will be an Array if startValue
and endValue are of type Array, otherwise the returned object will be
of type Vector.
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.
