public final class Util

extends Object

This class provides some static convenience methods and temporary scratch variables.

Field Summary

static double	EPSILON A reasonable small value ( 0.000001 ) useful for approximating 0.0.
static float[]	FLOAT2 A 2-dimensional float array that may be used as temporary scratch variable.
static float[]	FLOAT6 A six-dimensional float array that may be used as temporary scratch variable, e.g. when working with PathIterators.
static Point2D	POINT2D A Point2D in double precicion that may be used as temporary scratch variable.
static AffineTransform	TRANSFORM An Affine Transform that may be used as temporary scratch variable.

Method Summary

static void	alias(Graphics2D g) Puts a graphics context in anti-aliasing mode.
static void	unalias(Graphics2D g) Turns off anti-aliasing mode of a graphics context.

Method Detail

alias

public static void alias(Graphics2D g)

Puts a graphics context in anti-aliasing mode. This method keeps track of a counter for each graphics context. The counter is increased each time this method is called. The counter is zero initially, whenever the counter gets positive, the rendering hint will be set.

unalias

public static void unalias(Graphics2D g)

Turns off anti-aliasing mode of a graphics context. This method keeps track of a counter for each graphics context. The counter is decreased each time this method is called. The counter is zero initially, whenever the counter gets non-positive, the rendering hint will be reset.
