Package androidx.constraintlayout.core.motion.utils

Class StopLogicEngine

java.lang.Object

androidx.constraintlayout.core.motion.utils.StopLogicEngine

All Implemented Interfaces:

StopEngine

public class StopLogicEngine
extends java.lang.Object
implements StopEngine

This contains the class to provide the logic for an animation to come to a stop. The setup defines a series of velocity gradients that gets to the desired position ending at 0 velocity. The path is computed such that the velocities are continuous
