/**
 * This class holds a collection of IntKeyframe objects and is called by ValueAnimator to calculate
 * values between those keyframes for a given animation. The class internal to the animation
 * package because it is an implementation detail of how Keyframes are stored and used.
 *
 * <p>This type-specific subclass of KeyframeSet, along with the other type-specific subclass for
 * float, exists to speed up the getValue() method when there is no custom
 * TypeEvaluator set for the animation, so that values can be calculated without autoboxing to the
 * Object equivalents of these primitive types.</p>
