Methods
-
applyTransform(transformFn)
src/ol/geom/geometrycollection.js, line 292 -
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.
-
Increases the revision counter and dispatches a 'change' event.
-
Make a complete copy of the geometry.
Returns:
Clone.
-
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
type
property.Name Type Description event
Object | ol.events.Event | string Event object.
-
Gets a value.
Name Type Description key
string Key name.
Returns:
Value.
-
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.
-
Get the extent of the geometry.
Name Type Description extent
ol.Extent Extent.
Returns:
extent Extent.
-
Return the geometries that make up this geometry collection.
Returns:
Geometries.
-
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.
-
Get the type of this geometry.
Returns:
Geometry type.
-
Returns true if this geometry includes the specified coordinate. If the coordinate is on the boundary of the geometry, returns false.
Name Type Description coordinate
ol.Coordinate Coordinate.
Returns:
Contains coordinate.
-
intersectsExtent(extent){boolean}
src/ol/geom/geometrycollection.js, line 216 -
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){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 99 -
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
inlistener
.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 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
inlistener
.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 the geometry around a given coordinate. This modifies the geometry coordinates in place.
Name Type Description angle
number Rotation angle in radians.
anchor
ol.Coordinate The rotation center.
-
Scale the geometry (with an optional origin). This modifies the geometry coordinates in place.
Name Type Description sx
number The scaling factor in the x-direction.
sy
number The scaling factor in the y-direction (defaults to sx).
anchor
ol.Coordinate The scale origin (defaults to the center of the geometry extent).
-
Sets a value.
Name Type Description key
string Key name.
value
* Value.
silent
boolean Update without triggering an event.
-
setGeometries(geometries)
src/ol/geom/geometrycollection.js, line 271 -
Set the geometries that make up this geometry collection.
Name Type Description geometries
Array.<ol.geom.Geometry> Geometries.
-
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.
silent
boolean 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 tolerance
number 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 source
ol.ProjectionLike The current projection. Can be a string identifier or a
ol.proj.Projection
object.destination
ol.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)
src/ol/geom/geometrycollection.js, line 309 -
Translate the geometry.
Name Type Description deltaX
number Delta X.
deltaY
number Delta Y.
-
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 thelistener
. -
Unsets a property.
Name Type Description key
string Key name.
silent
boolean Unset without triggering an event.
