Constructor Summary

FPointIterator(java.awt.geom.Point2D p, java.awt.geom.AffineTransform at)
Creates a new PointIterator object.

Method Summary

int	currentSegment(double[] coords) Returns the coordinates and type of the current path segment in the iteration.
int	currentSegment(float[] coords) Returns the coordinates and type of the current path segment in the iteration.
int	getWindingRule() Return the winding rule for determining the interior of the path.
boolean	isDone() Tests if there are more points to read.
void	next() Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.

Constructor Detail

FPointIterator

public FPointIterator(java.awt.geom.Point2D p,
                      java.awt.geom.AffineTransform at)

Creates a new PointIterator object.

Parameters:

p - The polygon

at - The affine transform applied to coordinates during iteration

Method Detail

getWindingRule

public int getWindingRule()

Return the winding rule for determining the interior of the path.

Specified by:

getWindingRule in interface java.awt.geom.PathIterator

Overrides:

getWindingRule in class GeneralPathXIterator

Returns:

WIND_EVEN_ODD by default.

PathIterator.WIND_EVEN_ODD, PathIterator.WIND_NON_ZERO

next

public void next()

Description copied from class: GeneralPathXIterator

Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.

Specified by:

next in interface java.awt.geom.PathIterator

Overrides:

next in class GeneralPathXIterator

See Also:

PathIterator.next()

isDone

public boolean isDone()

Description copied from class: GeneralPathXIterator

Tests if there are more points to read.

Specified by:

isDone in interface java.awt.geom.PathIterator

Overrides:

isDone in class GeneralPathXIterator

Returns:

true if there are more points to read

See Also:

PathIterator.isDone()

currentSegment

public int currentSegment(double[] coords)

Description copied from class: GeneralPathXIterator

Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

Specified by:

currentSegment in interface java.awt.geom.PathIterator

Overrides:

currentSegment in class GeneralPathXIterator

See Also:

PathIterator.currentSegment(double[])

currentSegment

public int currentSegment(float[] coords)

Description copied from class: GeneralPathXIterator

Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A float array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

Specified by:

currentSegment in interface java.awt.geom.PathIterator

Overrides:

currentSegment in class GeneralPathXIterator
