IntEvaluator

java.lang.Object

public class IntEvaluator extends Object implements TypeEvaluator

This evaluator can be used to perform type interpolation between int values.

Fields Summary
Constructors Summary
Methods Summary
public java.lang.Integer evaluate(float fraction, java.lang.Integer startValue, java.lang.Integer endValue)
This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (v1 - v0), where x0 is startValue, x1 is endValue, and t is fraction.
param
fraction The fraction from the starting to the ending values
param
startValue The start value; should be of type int or Integer
param
endValue The end value; should be of type int or Integer
return
A linear interpolation between the start and end values, given the fraction parameter.
int startInt = startValue; return (int)(startInt + fraction * (endValue - startInt));
