# Enum Class Interpolator.StepPosition

java.lang.Object
java.lang.Enum<Interpolator.StepPosition>
javafx.animation.Interpolator.StepPosition

All Implemented Interfaces:
  `Serializable`, `Comparable<Interpolator.StepPosition>`, `Constable`

Enclosing class:
  `Interpolator`

public static enum Interpolator.StepPosition extends Enum<Interpolator.StepPosition>
Specifies the step position of a step interpolator.

The step position determines the location of rise points in the input progress interval, which are the locations on the input progress axis where the output progress value jumps from one step to the next.

Since:
  23
