IntEvaluator


class IntEvaluator : TypeEvaluator


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

Summary

Public functions

Int
evaluate(fraction: Float, startValue: Int, endValue: Int)

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values.

java-static IntEvaluator

Returns an instance of IntEvaluator that may be used in setEvaluator.

Public functions

evaluate

fun evaluate(fraction: Float, startValue: Int, endValue: Int): Int

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 * (x1 - x0), where x0 is startValue, x1 is endValue, and t is fraction.

Parameters
fraction: Float

The fraction from the starting to the ending values

startValue: Int

The start value; should be of type int or Integer

endValue: Int

The end value; should be of type int or Integer

Returns
Int

A linear interpolation between the start and end values, given the fraction parameter.

getInstance

java-static fun getInstance(): IntEvaluator

Returns an instance of IntEvaluator that may be used in setEvaluator. The same instance may be used in multiple Animators because it holds no state.

Returns
IntEvaluator

An instance of IntEvaluator.
