org.locationtech.jts.awt.PolygonShape

All Implemented Interfaces:

Shape

public class PolygonShape
extends Object
implements Shape

A Shape which represents a polygon which may contain holes. Provided because the standard AWT Polygon class does not support holes.

Constructor Details

PolygonShape

public PolygonShape(Coordinate[] shellVertices,
 Collection holeVerticesCollection)

Creates a new polygon Shape.

Parameters:

shellVertices - the vertices of the shell

holeVerticesCollection - a collection of Coordinate[] for each hole

PolygonShape

public PolygonShape()

Method Details

addToRing

void addToRing(Point2D p)

endRing

void endRing()

toPath

private GeneralPath toPath(Coordinate[] coordinates)

Creates a GeneralPath representing a polygon ring having the given coordinate sequence. Uses the GeneralPath.WIND_EVEN_ODD winding rule.

Parameters:

coordinates - a coordinate sequence

Returns:

the path for the coordinate sequence
