Constructors

GeometryFactoryEx()

Constructs a GeometryFactory that generates Geometries having a floating PrecisionModel and a spatial-reference ID of 0.

public GeometryFactoryEx()

GeometryFactoryEx(CoordinateSequenceFactory)

Constructs a GeometryFactory that generates Geometries having the given CoordinateSequence implementation, a double-precision floating PrecisionModel and a spatial-reference ID of 0.

public GeometryFactoryEx(CoordinateSequenceFactory coordinateSequenceFactory)

Parameters

coordinateSequenceFactory CoordinateSequenceFactory

GeometryFactoryEx(PrecisionModel)

Constructs a GeometryFactory that generates Geometries having the given {PrecisionModel} and the default CoordinateSequence implementation.

public GeometryFactoryEx(PrecisionModel precisionModel)

Parameters

precisionModel PrecisionModel

The PrecisionModel to use.

GeometryFactoryEx(PrecisionModel, int)

Constructs a GeometryFactory that generates Geometries having the given PrecisionModel and spatial-reference ID, and the default CoordinateSequence implementation.

public GeometryFactoryEx(PrecisionModel precisionModel, int srid)

Parameters

precisionModel PrecisionModel

The PrecisionModel to use.

srid int

The SRID to use.

GeometryFactoryEx(PrecisionModel, int, CoordinateSequenceFactory)

Constructs a GeometryFactory that generates Geometries having the given PrecisionModel, spatial-reference ID, and CoordinateSequence implementation.

public GeometryFactoryEx(PrecisionModel precisionModel, int srid, CoordinateSequenceFactory coordinateSequenceFactory)

Parameters

precisionModel PrecisionModel

srid int

coordinateSequenceFactory CoordinateSequenceFactory

GeometryFactoryEx(PrecisionModel, int, CoordinateSequenceFactory, NtsGeometryServices)

Constructs a GeometryFactory that generates Geometries having the given PrecisionModel, spatial-reference ID, and CoordinateSequence implementation.

public GeometryFactoryEx(PrecisionModel precisionModel, int srid, CoordinateSequenceFactory coordinateSequenceFactory, NtsGeometryServices services)

Parameters

precisionModel PrecisionModel

srid int

coordinateSequenceFactory CoordinateSequenceFactory

services NtsGeometryServices

Properties

DefaultCoordinateSequenceFactory

Gets or sets the default coordinate sequence factory to use with these geometry factories

public static CoordinateSequenceFactory DefaultCoordinateSequenceFactory { get; set; }

Property Value

CoordinateSequenceFactory

DefaultPrecisionModel

Gets or sets the default precision model to use with these geometry factories

public static PrecisionModel DefaultPrecisionModel { get; set; }

Property Value

PrecisionModel

DefaultSRID

Gets or sets the default spatial reference id.

public static int DefaultSRID { get; set; }

Property Value

int

OrientationOfExteriorRing

Gets or sets a value indicating the ring orientation of the Polygon's exterior rings.

If its value is DontCare, this factory behaves just like the base GeometryFactory.

public LinearRingOrientation OrientationOfExteriorRing { get; set; }

Property Value

LinearRingOrientation

Remarks

The setter of this property has to be used prior to any call to CreatePolygon, CreateMultiPolygon, or ReplaceSRID

Methods

CreateMultiPolygon(Polygon[])

Creates a MultiPolygon using the given Polygons; a null or empty array will create an empty Polygon. The polygons must conform to the assertions specified in the http://www.opengis.org/techno/specs.htm OpenGIS Simple Features Specification for SQL.

The OrientationOfExteriorRing is enforced on each polygon.

public override MultiPolygon CreateMultiPolygon(Polygon[] polygons)

Parameters

polygons Polygon[]

Polygons, each of which may be empty but not null.

Returns

MultiPolygon

A MultiPolygon object

CreatePolygon(LinearRing, LinearRing[])

Constructs a Polygon with the given exterior boundary and interior boundaries.

The OrientationOfExteriorRing is enforced on the constructed polygon.

public override Polygon CreatePolygon(LinearRing shell, LinearRing[] holes)

Parameters

shell LinearRing

The outer boundary of the new Polygon, or null or an empty LinearRing if the empty point is to be created.

holes LinearRing[]

The inner boundaries of the new Polygon, or null or empty LinearRing s if the empty point is to be created.

Returns

Polygon

A Polygon object

WithSRID(int)

public override GeometryFactory WithSRID(int srid)

Parameters

srid int

Returns

GeometryFactory
