Constructor Detail

GeometricShapeBuilder

public GeometricShapeBuilder(GeometryFactory geomFactory)

Method Detail

setExtent

public void setExtent(Envelope extent)

getExtent

public Envelope getExtent()

getCentre

public Coordinate getCentre()

getDiameter

public double getDiameter()

getRadius

public double getRadius()

getSquareBaseLine

public LineSegment getSquareBaseLine()

getSquareExtent

public Envelope getSquareExtent()

setNumPoints

public void setNumPoints(int numPts)

Sets the total number of points in the created Geometry. The created geometry will have no more than this number of points, unless more are needed to create a valid geometry.

getGeometry

public abstract Geometry getGeometry()

createCoord

protected Coordinate createCoord(double x,
                                 double y)
