Methods

appendLineString(lineString)

src/ol/geom/multilinestring.js, line 63

Append the passed linestring to the multilinestring.

Name	Type	Description
lineString	ol.geom.LineString	LineString.

applyTransform(transformFn) inherited

src/ol/geom/simplegeometry.js, line 260

Apply a transform function to each coordinate of the geometry. The geometry is modified in place. If you do not want the geometry modified in place, first clone() it and then use this function on the clone.

Name	Type	Description
transformFn	ol.TransformFunction	Transform.

changed() inherited experimental

src/ol/observable.js, line 52

Increases the revision counter and dispatches a 'change' event.

Fires:

• change experimental

clone(){ol.geom.MultiLineString}

src/ol/geom/multilinestring.js, line 82

Make a complete copy of the geometry.

Returns:

Clone.

get(key){*} inherited

src/ol/object.js, line 150

Gets a value.

Name	Type	Description
key	string	Key name.

Returns:

Value.

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

src/ol/geom/geometry.js, line 122

Return the closest point of the geometry to the passed point as coordinate.

Name	Type	Description
point	ol.Coordinate	Point.
closestPoint	ol.Coordinate	Closest point.

Returns:

Closest point.

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

src/ol/geom/multilinestring.js, line 132

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.

opt_interpolate controls interpolation between consecutive LineStrings within the MultiLineString. If opt_interpolate is true the coordinates will be linearly interpolated between the last coordinate of one LineString and the first coordinate of the next LineString. If opt_interpolate is false then the function will return null for Ms falling between LineStrings.

Name	Type	Description
m	number	M.
extrapolate	boolean	Extrapolate. Default is false.
interpolate	boolean	Interpolate. Default is false.

Returns:

Coordinate.

getCoordinates(){Array.<Array.<ol.Coordinate>>}

src/ol/geom/multilinestring.js, line 151

Return the coordinates of the multilinestring.

Returns:

Coordinates.

getExtent(opt_extent){ol.Extent} inherited

src/ol/geom/geometry.js, line 161

Get the extent of the geometry.

Name	Type	Description
extent	ol.Extent	Extent.

Returns:

extent Extent.

getFirstCoordinate(){ol.Coordinate} inherited

src/ol/geom/simplegeometry.js, line 112

Return the first coordinate of the geometry.

Returns:

First coordinate.

getKeys(){Array.<string>} inherited

src/ol/object.js, line 164

Get a list of object property names.

Returns:

List of property names.

getLastCoordinate(){ol.Coordinate} inherited

src/ol/geom/simplegeometry.js, line 130

Return the last coordinate of the geometry.

Returns:

Last point.

getLayout(){ol.geom.GeometryLayout} inherited

src/ol/geom/simplegeometry.js, line 140

Return the layout of the geometry.

Returns:

Layout.

getLineString(index){ol.geom.LineString}

src/ol/geom/multilinestring.js, line 171

Return the linestring at the specified index.

Name	Type	Description
index	number	Index.

Returns:

LineString.

getLineStrings(){Array.<ol.geom.LineString>}

src/ol/geom/multilinestring.js, line 189

Return the linestrings of this multilinestring.

Returns:

LineStrings.

getProperties(){Object.<string, *>} inherited

src/ol/object.js, line 174

Name	Type	Description
extent	ol.Extent	Extent.

Returns:

true if the geometry and the extent intersect.

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

src/ol/observable.js, line 75

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

Returns:

Unique key for the listener.

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

src/ol/observable.js, line 88

Name	Type	Description
type	string | Array.<string>	The event type or array of event types.
