Class Arc2D.Float

public static class Arc2D.Float extends Arc2D

This class implements an arc in float precision.

Since: 1.2

Field Summary
float	extent The extent angle of this arc, in degrees.
float	height The height of the box bounding the ellipse of this arc.
float	start The start angle of this arc, in degrees.
float	width The width of the box bounding the ellipse of this arc.
float	x The x coordinate of the box bounding the ellipse of this arc.
float	y The y coordinate of the box bounding the ellipse of this arc.

Constructor Summary
	Float() Create a new, open arc at (0,0) with 0 extent.
	Float(int type) Create a new arc of the given type at (0,0) with 0 extent.
	Float(float x, float y, float w, float h, float start, float extent, int type) Create a new arc with the given dimensions.
	Float(Rectangle2D r, float start, float extent, int type) Create a new arc with the given dimensions.

Method Summary
double	getAngleExtent() Return the extent of the arc, in degrees.
double	getAngleStart() Return the start angle of the arc, in degrees.
double	getHeight() Return the height of the bounding box.
double	getWidth() Return the width of the bounding box.
double	getX() Return the x coordinate of the bounding box.
double	getY() Return the y coordinate of the bounding box.
boolean	isEmpty() Tests if the arc contains points.
protected Rectangle2D	makeBounds(double x, double y, double w, double h) Creates a tight bounding box given dimensions that more precise than the bounding box of the ellipse.
void	setAngleExtent(double extent) Sets the extent angle of the arc.
void	setAngleStart(double start) Sets the start angle of the arc.
void	setArc(double x, double y, double w, double h, double start, double extent, int type) Sets the arc to the given dimensions.
