Methods

appendLineString(lineString)

src/ol/geom/multilinestring.js, line 61
Name Type Description
lineString ol.geom.LineString

LineString.

applyTransform(transformFn) inherited

src/ol/geom/simplegeometry.js, line 244

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 disptches a 'change' event.

Fires:
  • change experimental

clone(){ol.geom.MultiLineString}

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

Make a complete copy of the geometry.

Returns:
Clone.

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

src/ol/geom/geometry.js, line 120
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 129

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/geometry.js, line 159

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 105
Returns:
First coordinate.

getLastCoordinate(){ol.Coordinate} inherited

src/ol/geom/simplegeometry.js, line 122
Returns:

getLayout(){ol.geom.GeometryLayout} inherited

src/ol/geom/simplegeometry.js, line 131
Returns:
Layout.

getLineString(index){ol.geom.LineString}

src/ol/geom/multilinestring.js, line 166
Name Type Description
index number

Index.

Returns:
LineString.

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

Returns:
LineStrings.

getRevision(){number} inherited experimental

src/ol/observable.js, line 62
Returns:
Revision.

getType(){ol.geom.GeometryType}

src/ol/geom/multilinestring.js, line 243

Get the type of this geometry.

Returns:
Geometry type.

intersectsExtent(extent){boolean} experimental

src/ol/geom/multilinestring.js, line 252

Test if the geometry and the passed extent intersect.

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

Listen for a certain type of event.

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

src/ol/geom/multilinestring.js, line 263
Name Type Description
coordinates Array.<Array.<ol.Coordinate>>

layout ol.geom.GeometryLayout

Layout.

transform(source, destination){ol.geom.Geometry} inherited

src/ol/geom/geometry.js, line 235

Transform each coordinate of the geometry from one coordinate reference system to another. The geometry is modified in place. For example, a line will be transformed to a line and a circle to a circle. If you do not want the geometry modified in place, first clone() it and then use this function on the clone.

Name Type Description
source ol.proj.ProjectionLike

The current projection. Can be a string identifier or a ol.proj.Projection object.

destination ol.proj.ProjectionLike

The desired projection. Can be a string identifier or a ol.proj.Projection object.

Returns:
This geometry. Note that original geometry is modified in place.
