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.

transform(source, destination){ol.geom.Circle}

src/ol/geom/circle.js, line 261

Transform each coordinate of the circle from one coordinate reference system to another. 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.

Internally a circle is currently represented by two points: the center of the circle [cx, cy], and the point to the right of the circle [cx + r, cy]. This transform function just transforms these two points. So the resulting geometry is also a circle, and that circle does not correspond to the shape that would be obtained by transforming every point of the original circle.

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.

un(type, listener, opt_this) inherited

src/ol/observable.js, line 101

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 114

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	Key name.
