Interface PathIterator

public interface PathIterator

Used to return the boundary of an IShape, one segment at a time.

Field Summary

Fields

Modifier and Type	Field and Description
static int	SEG_CLOSE Indicates that the preceding subpath should be closed by appending a line segment back to the point corresponding to the most recent SEG_MOVETO.
static int	SEG_CUBICTO Indicates a pair of points that specify a cubic parametric curve to be drawn from the most recently specified point.
static int	SEG_LINETO Indicates the end point of a line to be drawn from the most recently specified point.
static int	SEG_MOVETO Indicates the starting location for a new subpath.
static int	SEG_QUADTO Indicates a pair of points that specify a quadratic parametric curve to be drawn from the most recently specified point.
static int	WIND_EVEN_ODD Specifies the even/odd rule for determining the interior of a path.
static int	WIND_NON_ZERO Specifies the non-zero rule for determining the interior of a path.

Method Summary

Modifier and Type	Method and Description
int	currentSegment(double[] coords) Returns the coordinates and type of the current path segment.
boolean	isDone() Returns true if this path has no additional segments.
void	next() Advances this path to the next segment.

Method Detail

windingRule

int windingRule()

Returns the winding rule used to determine the interior of this path.

isDone

boolean isDone()

Returns true if this path has no additional segments.

next

void next()

Advances this path to the next segment.

currentSegment

int currentSegment(double[] coords)

Returns the coordinates and type of the current path segment. The number of points stored in coords differs by path segment type: 0 - SEG_CLOSE, 1 - SEG_MOVETO, SEG_LINETO, 2 - SEG_QUADTO, 3 - SEG_CUBICTO.

Parameters:

coords - a buffer into which the current coordinates will be copied. It must be of length 6. Each point is stored as a pair of x,y coordinates.

Returns:

the path segment type, e.g. SEG_MOVETO.
