interface Interpolator

Known direct subclasses

AccelerateDecelerateInterpolator, AccelerateInterpolator, AnticipateInterpolator, AnticipateOvershootInterpolator, BounceInterpolator, CycleInterpolator, DecelerateInterpolator, LinearInterpolator, OvershootInterpolator, PathInterpolator

`AccelerateDecelerateInterpolator`	An interpolator where the rate of change starts and ends slowly but accelerates through the middle.
`AccelerateInterpolator`	An interpolator where the rate of change starts out slowly and then accelerates.
`AnticipateInterpolator`	An interpolator where the change starts backward then flings forward.
`AnticipateOvershootInterpolator`	An interpolator where the change starts backward then flings forward and overshoots the target value and finally goes back to the final value.
`BounceInterpolator`	An interpolator where the change bounces at the end.
`CycleInterpolator`	Repeats the animation for a specified number of cycles.
`DecelerateInterpolator`	An interpolator where the rate of change starts out quickly and then decelerates.
`LinearInterpolator`	An interpolator where the rate of change is constant
`OvershootInterpolator`	An interpolator where the change flings forward and overshoots the last value then comes back.
`PathInterpolator`	An interpolator that can traverse a Path that extends from `Point(0, 0)` to `(1, 1)`.

An interpolator defines the rate of change of an animation. This allows animations to have non-linear motion, such as acceleration and deceleration.

Summary

Public functions
`Float`	`getInterpolation(input: @FloatRange(from = 0, to = 1) Float)` Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction.

Public functions

getInterpolation

fun getInterpolation(input: @FloatRange(from = 0, to = 1) Float): Float

Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction. This interpolated value is then multiplied by the change in value of an animation to derive the animated value at the current elapsed animation time.

Parameters
`input: @FloatRange(from = 0, to = 1) Float`	A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end

Returns
`Float`	The interpolation value. This value can be more than 1.0 for interpolators which overshoot their targets, or less than 0 for interpolators that undershoot their targets.
