Fires:
-
change

Methods
-
Apply a transform function to the coordinates 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
TransformFunction Transform function. Called with a flat array of geometry coordinates.
-
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
BaseEvent | string Event object.
Returns:
false
if anyone called preventDefault on the event object or if any of the listeners returned false.
-
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
Coordinate Point.
closestPoint
Coordinate | undefined Closest point.
Returns:
Closest point.
-
Return the coordinate of the point.
Returns:
Coordinates.
-
Get the extent of the geometry.
Name Type Description extent
Extent | undefined Extent.
Returns:
extent Extent.
-
Return the first coordinate of the geometry.
Returns:
First coordinate.
-
Get a list of object property names.
Returns:
List of property names.
-
Return the last coordinate of the geometry.
Returns:
Last point.
-
Return the
layout
of the geometry.Returns:
Layout.
-
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
Coordinate Coordinate.
Returns:
Contains coordinate.
-
Test if the geometry and the passed extent intersect.
Name Type Description extent
Extent Extent.
Returns:
true
if the geometry and the extent intersect.
-
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.
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.
-
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.
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 counter-clockwise radians.
anchor
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 | undefined The scaling factor in the y-direction (defaults to sx).
anchor
Coordinate | undefined 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 | undefined Update without triggering an event.
-
Name Type Description coordinates
Array.<*> Coordinates.
layout
GeometryLayout | undefined Layout.
-
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 | undefined Update without triggering an event.
-
Create a simplified version of this geometry. For linestrings, this uses 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
ProjectionLike The current projection. Can be a string identifier or a
Projection
object.destination
ProjectionLike The desired projection. Can be a string identifier or a
Projection
object.Returns:
This geometry. Note that original geometry is modified in place.
-
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.
-
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.
-
Unsets a property.
Name Type Description key
string Key name.
silent
boolean | undefined Unset without triggering an event.
