public class DoubleUnaryOperators
extends Object

Utility methods to create DoubleUnaryOperator instances

Method Summary

Modifier and Type	Method and Description
static DoubleUnaryOperator	affine(double factor, double addend) Returns a DoubleUnaryOperator that is an affine transformation, returning factor * value + addend.
static DoubleUnaryOperator	clamp(DoubleUnaryOperator function, double min, double max) Returns a DoubleUnaryOperator that clamps the results from the given function to the interval [min,max]
static DoubleUnaryOperator	interpolate(double min, double max) Returns a DoubleUnaryOperator that maps the interval [0,1] to the interval [min,max]
static DoubleUnaryOperator	interpolate(double minSource, double maxSource, double minTarget, double maxTarget) Returns a DoubleUnaryOperator that maps the interval [minSource,maxSource] to the interval [minTarget,maxTarget], interpolating linearly.

Method Detail

interpolate

public static DoubleUnaryOperator interpolate(double min,
                                              double max)

Returns a DoubleUnaryOperator that maps the interval [0,1] to the interval [min,max]

Parameters:

min - The minimum value

max - The maximum value

Returns:

The DoubleUnaryOperator

interpolate

public static DoubleUnaryOperator interpolate(double minSource,
                                              double maxSource,
                                              double minTarget,
                                              double maxTarget)

Returns a DoubleUnaryOperator that maps the interval [minSource,maxSource] to the interval [minTarget,maxTarget], interpolating linearly.

The caller is responsible for passing sensible values. Particularly, the minSource and maxSource value should have a reasonable difference.

Parameters:

minSource - The minimum source value

maxSource - The maximum source value

minTarget - The minimum target value

maxTarget - The maximum target value

Returns:

The DoubleUnaryOperator

clamp

public static DoubleUnaryOperator clamp(DoubleUnaryOperator function,
                                        double min,
                                        double max)

Returns a DoubleUnaryOperator that clamps the results from the given function to the interval [min,max]

Parameters:

function - The function to clamp

min - The minimum value

max - The maximum value

Returns:

The DoubleUnaryOperator

affine

public static DoubleUnaryOperator affine(double factor,
                                         double addend)

Returns a DoubleUnaryOperator that is an affine transformation, returning factor * value + addend.

Parameters:

factor - The factor

addend - The addend

Returns:

The DoubleUnaryOperator
