Methods

applyTransform(transformFn)

src/ol/geom/geometrycollection.js, line 264

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.GeometryCollection}

src/ol/geom/geometrycollection.js, line 89

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 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.

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.

getGeometries(){Array.<ol.geom.Geometry>}

src/ol/geom/geometrycollection.js, line 148

Return the geometries that make up this geometry collection.

Returns:
Geometries.

getKeys(){Array.<string>} inherited

src/ol/object.js, line 164

Get a list of object property names.

Returns:
List of property names.

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/geometrycollection.js, line 209

Get the type of this geometry.

Returns:
Geometry type.

intersectsExtent(extent){boolean}

src/ol/geom/geometrycollection.js, line 218

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 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.

setGeometries(geometries)

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

Set the geometries that make up this geometry collection.

Name Type Description
geometries Array.<ol.geom.Geometry>

Geometries.

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) experimental

src/ol/geom/geometrycollection.js, line 280

Translate the geometry.

Name Type Description
deltaX number

Delta X.

deltaY number

Delta Y.

un(type, listener, opt_this) inherited

src/ol/observable.js, line 109

Unlisten 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 which was used as this by the listener.

unByKey(key) inherited

src/ol/observable.js, line 122

Removes an event listener using the key returned by on() or once(). Note that using the ol.Observable.unByKey static function is to be preferred.

Name Type Description
key goog.events.Key

The key returned by on() or once().

unset(key) inherited

src/ol/object.js, line 229

Unsets a property.

Name Type Description
key string
