Methods

applyTransform(transformFn)

geom/SimpleGeometry.js, line 209

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	module:ol/proj~TransformFunction	Transform function. Called with a flat array of geometry coordinates.

changed() inherited

Observable.js, line 70

Increases the revision counter and dispatches a 'change' event.

dispatchEvent(event){boolean|undefined} inherited

events/Target.js, line 85

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	module:ol/events/Event~BaseEvent | string	Event object.

Returns:

false if anyone called preventDefault on the event object or if any of the listeners returned false.

get(key){*} inherited

Object.js, line 135

Gets a value.

Name	Type	Description
key	string	Key name.

Returns:

Value.

getClosestPoint(point, opt_closestPoint){module:ol/coordinate~Coordinate} inherited

geom/Geometry.js, line 142

Return the closest point of the geometry to the passed point as coordinate.

Name	Type	Description
point	module:ol/coordinate~Coordinate	Point.
closestPoint	module:ol/coordinate~Coordinate	Closest point.

Returns:

Closest point.

getExtent(opt_extent){module:ol/extent~Extent} inherited

geom/Geometry.js, line 175

Get the extent of the geometry.

Name	Type	Description
extent	module:ol/extent~Extent	Extent.

Returns:

extent Extent.

getFirstCoordinate(){module:ol/coordinate~Coordinate}

geom/SimpleGeometry.js, line 69

Return the first coordinate of the geometry.

Returns:

First coordinate.

getKeys(){Array.<string>} inherited

Object.js, line 148

Get a list of object property names.

Returns:

List of property names.

getLastCoordinate(){module:ol/coordinate~Coordinate}

geom/SimpleGeometry.js, line 85

Return the last coordinate of the geometry.

Returns:

Last point.

getLayout(){module:ol/geom/GeometryLayout}

geom/SimpleGeometry.js, line 96

Return the layout of the geometry.

Returns:

Layout.

getProperties(){Object.<string, *>} inherited

Object.js, line 157

Get an object of all property names and values.

Returns:

Object.

getRevision(){number} inherited

Observable.js, line 81

Get the version number for this object. Each time the object is modified, its version number will be incremented.

Returns:

Revision.

intersectsCoordinate(coordinate){boolean} inherited

geom/Geometry.js, line 155

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	module:ol/coordinate~Coordinate	Coordinate.

Returns:

Contains coordinate.

on(type, listener){module:ol/events~EventsKey|Array.<module:ol/events~EventsKey>} inherited

Observable.js, line 155

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.

once(type, listener){module:ol/events~EventsKey|Array.<module:ol/events~EventsKey>} inherited

Observable.js, line 167

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(angle, anchor)

geom/SimpleGeometry.js, line 223

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	module:ol/coordinate~Coordinate	The rotation center.

scale(sx, opt_sy, opt_anchor)

geom/SimpleGeometry.js, line 249

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	module:ol/coordinate~Coordinate	The scale origin (defaults to the center of the geometry extent).

set(key, value, opt_silent) inherited

Object.js, line 203

Sets a value.

Name	Type	Description
key	string	Key name.
value	*	Value.
silent	boolean	Update without triggering an event.

setProperties(values, opt_silent) inherited

Object.js, line 223

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.

simplify(tolerance){module:ol/geom/Geometry~Geometry} inherited

geom/Geometry.js, line 221

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(source, destination){module:ol/geom/Geometry~Geometry} inherited

geom/Geometry.js, line 296

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	module:ol/proj~ProjectionLike	The current projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.
destination	module:ol/proj~ProjectionLike	The desired projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.

Returns:

This geometry. Note that original geometry is modified in place.

translate(deltaX, deltaY)

geom/SimpleGeometry.js, line 282

Translate the geometry. This modifies the geometry coordinates in place. If instead you want a new geometry, first clone() this geometry.

listener	function	The listener function.

unset(key, opt_silent) inherited

Object.js, line 247

Unsets a property.

Name	Type	Description
key	string	Key name.
silent	boolean	Unset without triggering an event.
