public final class PathInterpolatorCompat

Helper for creating path-based Interpolator instances. On API 21 or newer, the platform implementation will be used and on older platforms a compatible alternative implementation will be used.

Summary

Public methods
`static @NonNull Interpolator`	`create(@NonNull Path path)` Create an `Interpolator` for an arbitrary `Path`.
`static @NonNull Interpolator`	`create(float controlX, float controlY)` Create an `Interpolator` for a quadratic Bezier curve.
`static @NonNull Interpolator`	`create( float controlX1, float controlY1, float controlX2, float controlY2 )` Create an `Interpolator` for a cubic Bezier curve.

Public methods

create

Added in 1.1.0

public static @NonNull Interpolator create(@NonNull Path path)

Create an Interpolator for an arbitrary Path. The Path must begin at (0, 0) and end at (1, 1). The x-coordinate along the Path is the input value and the output is the y coordinate of the line at that point. This means that the Path must conform to a function y = f(x).

The Path must not have gaps in the x direction and must not loop back on itself such that there can be two points sharing the same x coordinate.

Parameters
`@NonNull Path path`	the `Path` to use to make the line representing the `Interpolator`

Returns
`@NonNull Interpolator`	the `Interpolator` representing the `Path`

public static @NonNull Interpolator create(float controlX, float controlY)

Create an Interpolator for a quadratic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`float controlX`	the x coordinate of the quadratic Bezier control point
`float controlY`	the y coordinate of the quadratic Bezier control point

Returns
`@NonNull Interpolator`	the `Interpolator` representing the quadratic Bezier curve

create

Added in 1.1.0

public static @NonNull Interpolator create(
    float controlX1,
    float controlY1,
    float controlX2,
    float controlY2
)

Create an Interpolator for a cubic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`float controlX1`	the x coordinate of the first control point of the cubic Bezier
`float controlY1`	the y coordinate of the first control point of the cubic Bezier
`float controlX2`	the x coordinate of the second control point of the cubic Bezier
`float controlY2`	the y coordinate of the second control point of the cubic Bezier

Returns
`@NonNull Interpolator`	the `Interpolator` representing the cubic Bezier curve
