java.lang.Object

android.animation.Animator

android.animation.ValueAnimator

com.airbnb.lottie.utils.LottieValueAnimator

All Implemented Interfaces:

java.lang.Cloneable

public class LottieValueAnimator
extends android.animation.ValueAnimator

This is a slightly modified ValueAnimator that allows us to update start and end values easily optimizing for the fact that we know that it's a value animator with 2 floats.
