Enum Constant Summary

Enum Constants

Enum Constant	Description
DECREASING	Hue angles are interpolated so that, as they progress from the first color to the second, the angle is always decreasing.
INCREASING	Hue angles are interpolated so that, as they progress from the first color to the second, the angle is always increasing.
LONGER	Hue angles are interpolated to take the longer of the two arcs between the starting and ending hues.
SHORTER	Hue angles are interpolated to take the shorter of the two arcs between the starting and ending hues.

Method Summary

Modifier and Type	Method	Description
static GradientShader.HueInterpolationMethod	valueOf(String name)	Returns the enum constant of this class with the specified name.
static GradientShader.HueInterpolationMethod[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

SHORTER

public static final GradientShader.HueInterpolationMethod SHORTER

Hue angles are interpolated to take the shorter of the two arcs between the starting and ending hues.

LONGER

public static final GradientShader.HueInterpolationMethod LONGER

Hue angles are interpolated to take the longer of the two arcs between the starting and ending hues.

INCREASING

public static final GradientShader.HueInterpolationMethod INCREASING

Hue angles are interpolated so that, as they progress from the first color to the second, the angle is always increasing. If the angle increases to 360 it is reset to zero, and then continues increasing.

Depending on the difference between the two angles, this will either look the same as shorter or as longer. However, if one of the hue angles is being animated, and the hue angle difference passes through 180 degrees, the interpolation will not flip to the other arc.

DECREASING

public static final GradientShader.HueInterpolationMethod DECREASING

Hue angles are interpolated so that, as they progress from the first color to the second, the angle is always decreasing. If the angle decreases to 0 it is reset to 360, and then continues decreasing.

Depending on the difference between the two angles, this will either look the same as shorter or as longer. However, if one of the hue angles is being animated, and the hue angle difference passes through 180 degrees, the interpolation will not flip to the other arc.

Method Details

values

public static GradientShader.HueInterpolationMethod[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static GradientShader.HueInterpolationMethod valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
