# Class CornerRadii

java.lang.Object
javafx.scene.layout.CornerRadii

All Implemented Interfaces:
  `Interpolatable<CornerRadii>`

public final class CornerRadii extends Object implements Interpolatable<CornerRadii>
Defines the radii of each of the four corners of a BorderStroke. The CornerRadii class is immutable and therefore can be reused on multiple BorderStrokes. This class defines 8 different values, corresponding to the horizontal and vertical components of 4 quarter ellipses, which in turn define the curvature of the corners of the BorderStroke.

Since:
  JavaFX 8.0

  - ### interpolate

    public CornerRadii interpolate(CornerRadii endValue, double t)
    Returns an intermediate value between the value of this `Interpolatable` and the specified `endValue` using the linear interpolation factor `t`. The interpolation factor can be any finite value.

    The returned value might not be a new instance; the implementation might also return one of the two existing instances if the intermediate value would be equal to one of the existing values. However, this is an optimization and applications should not assume any particular identity of the returned value.

    Specified by:
      `interpolate` in interface `Interpolatable<CornerRadii>`
    Parameters:
      `endValue` - the target value
      `t` - the interpolation factor
    Returns:
      the intermediate value
    Throws:
      `NullPointerException` - if `endValue` is `null`
