Field Summary

Fields

Modifier and Type	Field and Description
static int	CHORD An arc type indicating a closed curve, connected by a straight line from the starting to the ending point of the arc.
static int	OPEN An arc type indicating a simple, unconnected curve.
static int	PIE An arc type indicating a closed curve, connected by a line from the starting point of the arc to the center of the circle defining the arc, and another straight line from that center to the ending point of the arc.

Method Summary

Modifier and Type	Method and Description
float	angleExtent() Returns the angular extent of this arc.
float	angleStart() Returns the starting angle of this arc.
int	arcType() Returns the type of this arc: OPEN, etc.
Arc	clone() Returns a mutable copy of this arc.
boolean	containsAngle(float angle) Returns whether the specified angle is within the angular extents of this arc.
Point	endPoint() Returns the intersection of the ray from the center (defined by the starting angle plus the angular extent of the arc) and the elliptical boundary of the arc.
Point	endPoint(Point target) Writes the intersection of the ray from the center (defined by the starting angle plus the angular extent of the arc) and the elliptical boundary of the arc into target.
Point	startPoint() Returns the intersection of the ray from the center (defined by the starting angle) and the elliptical boundary of the arc.
Point	startPoint(Point target) Writes the intersection of the ray from the center (defined by the starting angle) and the elliptical boundary of the arc into target.
