Methods

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 51

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

clone(){ol.geom.LinearRing}

Make a complete copy of the geometry.

Returns:

Clone.

get(key){*} inherited

Gets a value.

Name	Type	Description
key	string	Key name.

Returns:

Value.

getArea(){number}

src/ol/geom/linearring.js, line 85

Return the area of the linear ring on projected plane.

Returns:

Area (on projected plane).

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

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

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.

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

src/ol/geom/linearring.js, line 96

Return the coordinates of the linear ring.

Returns:

Coordinates.

getExtent(opt_extent){ol.Extent} inherited

src/ol/geom/geometry.js, line 163

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.

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

src/ol/object.js, line 174

Get an object of all property names and values.

Returns:

Object.

getRevision(){number} inherited experimental

src/ol/observable.js, line 70

Get the version number for this object. Each time the object is modified, its version number will be incremented.

Returns:

Revision.

getType(){ol.geom.GeometryType}

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

Get the type of this geometry.

Returns:

Geometry type.

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

src/ol/observable.js, line 83

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 96

Listen once 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.

set(key, value) inherited

src/ol/object.js, line 203

Sets a value.

Name	Type	Description
key	string	Key name.
value	*	Value.

setCoordinates(coordinates, opt_layout)

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

Set the coordinates of the linear ring.

Name	Type	Description
coordinates	Array.<ol.Coordinate>	Coordinates.
layout	ol.geom.GeometryLayout	Layout.

setProperties(values) inherited

src/ol/object.js, line 216

Sets a collection of key-value pairs. Note that this changes any existing properties and adds new ones (it does not remove any existing properties).

Name	Type	Description
values	Object.<string, *>	Values.

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

src/ol/geom/geometry.js, line 236

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.

translate(deltaX, deltaY) inherited

src/ol/geom/simplegeometry.js, line 272

Translate the geometry. This modifies the geometry coordinates in place. If instead you want a new geometry, first clone() this geometry.

Name	Type	Description
deltaX	number	Delta X.
deltaY	number	Delta Y.

listener	function	The listener function.
this	Object	The object which was used as this by the listener.

unByKey(key) inherited
