Functions ¶

func Marshal ¶

func Marshal(g orb.Geometry) []byte

Marshal returns a WKT representation of the geometry.

func MarshalString ¶

func MarshalString(g orb.Geometry) string

MarshalString returns a WKT representation of the geometry as a string.

func Unmarshal ¶

func Unmarshal(s string) (geom orb.Geometry, err error)

Unmarshal return a geometry by parsing the WKT string.

func UnmarshalCollection ¶

func UnmarshalCollection(s string) (p orb.Collection, err error)

UnmarshalCollection returns the geometry collection represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a geometry collection.

func UnmarshalLineString ¶

func UnmarshalLineString(s string) (p orb.LineString, err error)

UnmarshalLineString returns the linestring represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a linestring.

func UnmarshalMultiLineString ¶

func UnmarshalMultiLineString(s string) (p orb.MultiLineString, err error)

UnmarshalMultiLineString returns the multi-linestring represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a multi-linestring.

func UnmarshalMultiPoint ¶

func UnmarshalMultiPoint(s string) (p orb.MultiPoint, err error)

UnmarshalMultiPoint returns the multi-point represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a multi-point.

func UnmarshalMultiPolygon ¶

func UnmarshalMultiPolygon(s string) (p orb.MultiPolygon, err error)

UnmarshalMultiPolygon returns the multi-polygon represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a multi-polygon.

func UnmarshalPoint ¶

func UnmarshalPoint(s string) (p orb.Point, err error)

UnmarshalPoint returns the point represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a point.

func UnmarshalPolygon ¶

func UnmarshalPolygon(s string) (p orb.Polygon, err error)

UnmarshalPolygon returns the polygon represented by the wkt string. Will return ErrIncorrectGeometry if the wkt is not a polygon.
