Class GeometryFactory

java.lang.Object

org.geolatte.geom.GeometryFactory

public class GeometryFactory
extends Object

A Factory for Geometrys.

This factory is provided as a convenience. It ensures that a set of Geometrys are created with the same spatial reference system and GeometryOperations implementation.

Constructor Detail

GeometryFactory

public GeometryFactory(GeometryOperations geometryOperations)

Creates a GeometryFactory that creates Geometrys with the specified GeometryOperations.

Parameters:

geometryOperations - the GeometryOperations implementation

GeometryFactory

public GeometryFactory()

Creates a GeometryFactory that creates Geometrys with the default GeometryOperations implementation.

Method Detail

createPoint

public Point createPoint(PointSequence points)

Creates a Point.

Parameters:

points - the coordinates of the point

Returns:

the Point with the specified coordinates

createLineString

public LineString createLineString(PointSequence points)

Creates a LineString

Parameters:

points - the points of the linestring

Returns:

createLinearRing

public LinearRing createLinearRing(PointSequence points)

Creates a LinearRing

Parameters:

points - the points of the ring

Returns:

a LinearRing with the specified points.

Throws:

IllegalArgumentException - if the input PointSequence does not form a closed ring.

createPolygon

public Polygon createPolygon(PointSequence points)

Creates a Polygon without any holes.

Parameters:

points - the points of the outer ring.

Returns:

createPolygon

public Polygon createPolygon(LinearRing[] rings)

Creates a Polygon .

The first LinearRing in the rings parameter is the outer ring (or shell) of this Polygon. The other rings determine holes within it.

Parameters:

rings - the LinearRings that defined this Polygon.

Returns:

createGeometryCollection

public GeometryCollection createGeometryCollection(Geometry[] geometries)

Creates a GeometryCollection from the specified Geometrys.

Parameters:

geometries - the constituent Geometrys for the new GeometryCollection. *

Returns:

createMultiPoint

public MultiPoint createMultiPoint(Point[] points)

Creates a MultiPoint from the specified Points.

Parameters:

points - the constituent Points of the new MultiPoint.

Returns:

createMultiLineString

public MultiLineString createMultiLineString(LineString[] lineStrings)

Creates a MultiLineString from the specified LineStrings.

Parameters:

lineStrings - the constituent LineStrings of the new MultiLineString.

Returns:

createMultiPolygon

public MultiPolygon createMultiPolygon(Polygon[] polygons)

Creates a MultiPolygon from the specified Polygons.

Parameters:

polygons - the constituent Polygons of the new MultiPolygon.

Returns:
