Methods

experimental appendCoordinate(coordinate)

src/ol/geom/linestring.js, line 64

Name	Type	Description
coordinate	ol.Coordinate	Coordinate.

experimental clone(){ol.geom.Geometry}

src/ol/geom/linestring.js, line 79

experimental inherited dispatchChangeEvent()

src/ol/observable.js, line 39

Dispatches a change event. Register a listener for this event to get notified of changes.

Fires:

• change

experimental inherited getClosestPoint(point, opt_closestPoint){ol.Coordinate}

src/ol/geom/geometry.js, line 111

Name	Type	Argument	Description
point	ol.Coordinate		Point.
closestPoint	ol.Coordinate	<optional>	optional Closest point.

Returns:

point.

experimental getCoordinateAtM(m, opt_extrapolate){ol.Coordinate}

src/ol/geom/linestring.js, line 120

Returns the coordinate at m using linear interpolation, or null if no such coordinate exists.

opt_extrapolate controls extrapolation beyond the range of Ms in the MultiLineString. If opt_extrapolate is true then Ms less than the first M will return the first coordinate and Ms greater than the last M will return the last coordinate.

Name	Type	Argument	Description
m	number		M.
extrapolate	boolean	<optional>	optional Extrapolate.

experimental getCoordinates(){ol.geom.RawLineString}

src/ol/geom/linestring.js, line 135

experimental inherited getExtent(opt_extent){ol.Extent}

src/ol/geom/simplegeometry.js, line 91

Get the extent of the geometry.

Name	Type	Argument	Description
extent	ol.Extent	<optional>	optional Extent.

Returns:

Extent.

experimental inherited getFirstCoordinate(){ol.Coordinate}

src/ol/geom/simplegeometry.js, line 107

Returns:

coordinate.

experimental inherited getLastCoordinate(){ol.Coordinate}

src/ol/geom/simplegeometry.js, line 124

Returns:

point.

experimental inherited getLayout(){ol.geom.GeometryLayout}

src/ol/geom/simplegeometry.js, line 133

experimental getLength(){number}

src/ol/geom/linestring.js, line 145

experimental inherited getSimplifiedGeometry(squaredTolerance){ol.geom.Geometry}

src/ol/geom/simplegeometry.js, line 142

Name	Type	Description
squaredTolerance	number	Squared tolerance.

Returns:

geometry.

experimental getType(){ol.geom.GeometryType}

src/ol/geom/linestring.js, line 185

Returns:

type.

experimental inherited on(type, listener, opt_this){goog.events.Key}

src/ol/observable.js, line 61

Name	Type	Argument	Description
type	string | Array.<string>		The event type or array of event types.
listener	function		The listener function.
this	Object	<optional>	optional The object to use as this in listener.

Returns:

key for the listener.

experimental setCoordinates(coordinates, opt_layout)

src/ol/geom/linestring.js, line 195

Name	Type	Argument	Description
coordinates	ol.geom.RawLineString		Coordinates.
layout	ol.geom.GeometryLayout	<optional>	optional Layout.
