Method Detail

createPoint

public Geometry createPoint(double x,
                            double y)

Creates a point Geometry

Parameters:

gp -

Returns:

createMultiPoint

public Geometry createMultiPoint(MultipointGeneralPath gp)

Creates a multipoint geometry. Each point in the general path will be a point in the multipoint geometry

Parameters:

gp -

Returns:

createMultiPoint

public Geometry createMultiPoint(double[] x,
                                 double[] y)

Creates a multipoint geometry

Parameters:

x -

y -

Returns:

createLineString

public Geometry createLineString(GeneralPath gp)

Creates a new linestring Geometry

Parameters:

gp -

Returns:

createPolygon

public Geometry createPolygon(ClosedGeneralPath shell)

Creates a polygon with no holes

Parameters:

shell -

Returns:

createPolygon

public Geometry createPolygon(ClosedGeneralPath shell,
                              ClosedGeneralPath[] holes)

Creates a new polygon geometry. The polygon shell vertices will be in clockwise order and the holes vertices will be in counterclockwise order. The shell and the holes are accesible by the getGeometry method in Geometry interface. The shell is always at the first position (getGeometry(0))

Parameters:

shell -

holes -

Returns:

createMultiLineString

public Geometry createMultiLineString(GeneralPath[] linestrings)

Creates a new MultiLineString geometry

Parameters:

linestrings -

Returns:

createMultiLineString

public Geometry createMultiLineString(Geometry[] linestrings)

Creates a new MultiLineString geometry

Parameters:

linestrings -

Returns:

createMultiPolygon

public Geometry createMultiPolygon(Geometry[] polygons)

Creates a new MultiPolygonString geometry

Parameters:

polygons -

Returns:
