Field Summary

Fields

Modifier and Type	Field and Description
protected int	np The total number of points.
protected int[]	x All the X-values of the coordinates in the polyline.
protected int[]	y All the Y-values of the coordinates in the polyline.

Constructor and Description
PolylineShape(int[] x, int[] y, int nPoints) Creates a PolylineShape.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	contains(double x, double y) A polyline can't contain a point.
boolean	contains(double x, double y, double w, double h) A polyline can't contain a point.
boolean	contains(Point2D p) A polyline can't contain a point.
boolean	contains(Rectangle2D r) A polyline can't contain a point.
Rectangle	getBounds() Returns the bounding box of this polyline.
Rectangle2D	getBounds2D() Returns the bounding box of this polyline.
PathIterator	getPathIterator(AffineTransform at) Returns an iteration object that defines the boundary of the polyline.
PathIterator	getPathIterator(AffineTransform at, double flatness) There's no difference with getPathIterator(AffineTransform at); we just need this method to implement the Shape interface.
boolean	intersects(double x, double y, double w, double h) Checks if one of the lines in the polyline intersects with a given rectangle.
boolean	intersects(Rectangle2D r) Checks if one of the lines in the polyline intersects with a given rectangle.

getPathIterator

public PathIterator getPathIterator(AffineTransform at)

Returns an iteration object that defines the boundary of the polyline.

Specified by:

getPathIterator in interface Shape

Parameters:

at - the specified AffineTransform

Returns:

a PathIterator that defines the boundary of this polyline.
