Overview

The abstract class defines the single interpolate() method, which is used to calculate interpolated values. Various built-in implementations of this class are offered. Applications may choose to implement their own Interpolator to get custom interpolation behavior.

publicDISCRETEInterpolator

Built-in interpolator that provides discrete time interpolation.

Built-in interpolator that provides discrete time interpolation. The return value of interpolate() is endValue only when the input faction is 1.0, and startValue otherwise.

Profile: common

 
publicEASEBOTHInterpolator

Built-in interpolator instance that provides ease in/out behavior.

Built-in interpolator instance that provides ease in/out behavior. It uses default values of 0.2 and 0.2 for the acceleration and deceleration factors, respectively.

Profile: common

 
publicEASEINInterpolator

Built-in interpolator instance that provides ease in behavior.

Built-in interpolator instance that provides ease in behavior. It uses value of 0.2 for the acceleration factor.

Profile: common

 
publicEASEOUTInterpolator

Built-in interpolator instance that provides ease out behavior.

Built-in interpolator instance that provides ease out behavior. It uses value of 0.2 for the deceleration factor.

Profile: common

 
publicLINEARInterpolator

Built-in interpolator that provides linear time interpolation.

Built-in interpolator that provides linear time interpolation. The return value of interpolate() is startValue + (endValue - startValue) * faction.

Script Function Summary

public SPLINE(x1: Number, y1: Number, x2: Number, y2: Number) : Interpolator

Built-in interpolator instance that is shaped using the spline control points defined by (x1, y1) and (x2, y2).

Built-in interpolator instance that is shaped using the spline control points defined by (x1, y1) and (x2, y2). The anchor points of the spline are implicitly defined as (0.0, 0.0) and (1.0, 1.0).

Parameters
x1
x coordinate of the first control point
y1
y coordinate of the first control point
x2
x coordinate of the second control point
y2
y coordinate of the second control point
Returns
Interpolator
A spline interpolator

Function Summary

public abstract interpolate(startValue: java.lang.Object, endValue: java.lang.Object, fraction: Number) : java.lang.Object

This function takes startValue and endValue along with faction between 0.0 and 1.0 and returns another value, between startValue and endValue.

This function takes startValue and endValue along with faction between 0.0 and 1.0 and returns another value, between startValue and endValue. The purpose of the function is to define how time (represented as a (0.0 - 1.0) fraction of the duration of an animation) is altered to derive different value calculations during an animation.

Parameters
startValue
start value
endValue
end value
fraction
a value between 0.0 and 1.0
Returns
Object
interpolated value
