encoding/wkt

This package provides encoding and decoding of WKT data. The interface is defined as:

func MarshalString(orb.Geometry) string

func Unmarshal(string) (orb.Geometry, error)
func UnmarshalPoint(string) (orb.Point, err error)
func UnmarshalMultiPoint(string) (orb.MultiPoint, err error)
func UnmarshalLineString(string) (orb.LineString, err error)
func UnmarshalMultiLineString(string) (orb.MultiLineString, err error)
func UnmarshalPolygon(string) (orb.Polygon, err error)
func UnmarshalMultiPolygon(string) (orb.MultiPolygon, err error)
func UnmarshalCollection(string) (orb.Collection, err error)

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) (orb.Geometry, error)

Unmarshal return a geometry by parsing the WKT string.

func UnmarshalCollection

func UnmarshalCollection(s string) (orb.Collection, 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) (orb.LineString, 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) (orb.MultiLineString, 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) (orb.MultiPoint, 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) (orb.MultiPolygon, 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) (orb.Point, 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) (orb.Polygon, error)

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