new ol.geom.Geometry()
Fires:
-
change(ol.events.Event) - Generic change event. Triggered when the revision counter is increased. -
propertychange(ol.Object.Event) - Triggered when a property is changed.

Methods
-
Increases the revision counter and dispatches a 'change' event.
-
Dispatches an event and calls all listeners listening for events of this type. The event parameter can either be a string or an Object with a
typeproperty.Name Type Description eventObject | ol.events.Event | string Event object.
-
Gets a value.
Name Type Description keystring Key name.
Returns:
Value.
-
Return the closest point of the geometry to the passed point as
coordinate.Name Type Description pointol.Coordinate Point.
closestPointol.Coordinate Closest point.
Returns:
Closest point.
-
Get the extent of the geometry.
Name Type Description extentol.Extent Extent.
Returns:
extent Extent.
-
Get a list of object property names.
Returns:
List of property names.
-
Get an object of all property names and values.
Returns:
Object.
-
Get the version number for this object. Each time the object is modified, its version number will be incremented.
Returns:
Revision.
-
intersectsCoordinate(coordinate){boolean}
src/ol/geom/geometry.js, line 112 -
Returns true if this geometry includes the specified coordinate. If the coordinate is on the boundary of the geometry, returns false.
Name Type Description coordinateol.Coordinate Coordinate.
Returns:
Contains coordinate.
-
on(type, listener, opt_this){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 99 -
Listen for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object to use as
thisinlistener.Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.
-
once(type, listener, opt_this){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 124 -
Listen once for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object to use as
thisinlistener.Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.
-
rotate(angle, anchor)
src/ol/geom/geometry.js, line 157 -
Rotate the geometry around a given coordinate. This modifies the geometry coordinates in place.
Name Type Description anglenumber Rotation angle in radians.
anchorol.Coordinate The rotation center.
-
scale(sx, opt_sy, opt_anchor)
src/ol/geom/geometry.js, line 171 -
Scale the geometry (with an optional origin). This modifies the geometry coordinates in place.
Name Type Description sxnumber The scaling factor in the x-direction.
synumber The scaling factor in the y-direction (defaults to sx).
anchorol.Coordinate The scale origin (defaults to the center of the geometry extent).
-
Sets a value.
Name Type Description keystring Key name.
value* Value.
silentboolean Update without triggering an event.
-
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 valuesObject.<string, *> Values.
silentboolean Update without triggering an event.
-
Create a simplified version of this geometry. For linestrings, this uses the the Douglas Peucker algorithm. For polygons, a quantization-based simplification is used to preserve topology.
Name Type Description tolerancenumber The tolerance distance for simplification.
Returns:
A new, simplified version of the original geometry.
-
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 sourceol.ProjectionLike The current projection. Can be a string identifier or a
ol.proj.Projectionobject.destinationol.ProjectionLike The desired projection. Can be a string identifier or a
ol.proj.Projectionobject.Returns:
This geometry. Note that original geometry is modified in place.
-
Unlisten for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object which was used as
thisby thelistener. -
Unsets a property.
Name Type Description keystring Key name.
silentboolean Unset without triggering an event.
