Property Details

cache

Inherited
Property
cache Objectreadonly
Inherited from Geometry

The cache is used to store values computed from geometries that need to be cleared or recomputed upon mutation. An example is the extent of a polygon.

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

The name of the class. The declared class name is formatted as esri.folder.className.

extent

Inherited
Property
extent Extentreadonly
Inherited from Geometry

The extent of the geometry. For a point, the extent is null.

hasM

Inherited
Property
hasM Boolean
Inherited from Geometry

Indicates if the geometry has M values.

hasZ

Inherited
Property
hasZ Boolean
Inherited from Geometry

Indicates if the geometry has z-values (elevation).

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

points

Property
points Number[][]

An array of points.

spatialReference

Inherited
Property
spatialReference SpatialReferenceautocast
Inherited from Geometry

The spatial reference of the geometry.

Default Value:WGS84 (wkid: 4326)

type

Property
type Stringreadonly

The string value representing the type of geometry.

For Multipoint the type is always "multipoint".

Method Details

addHandles

Inherited
Method
addHandles(handleOrHandles, groupKey)
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

addPoint

Method
addPoint(point){Multipoint}

Adds a point to the Multipoint.

Parameter
point Point|Number[]

The point to add to the multipoint. The point can either be a Point or an array of numbers representing XY coordinates.

Returns
Type Description
Multipoint Returns the updated Multipoint.

clone

Method
clone(){Multipoint}

Creates a deep clone of Multipoint object.

Returns
Type Description
Multipoint A new instance of a Multipoint object equal to the object used to call .clone().

fromJSON

Inherited
Method
fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter
json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns
Type Description
* Returns a new instance of this class.

Method
getPoint(index){Point}

Returns the point at the specified index.

Parameter
index Number

The index of the point in the points property.

Returns
Type Description
Point The point at the specified index.

hasHandles

Method
hasHandles(groupKey){Boolean}
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter
groupKey *
optional

A group key.

Returns
Type Description
Boolean Returns true if a named group of handles exist.
Example
// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles

Parameter
groupKey *
optional

A group key or an array or collection of group keys to remove.

Example
obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");

removePoint

Method
removePoint(index){Point}

Removes a point from the Multipoint. The index specifies which point to remove.

Parameter
index Number

The index of the point to remove.

Returns
Type Description
Point Returns the removed point.

setPoint

Method
setPoint(index, point){Multipoint}

Updates the point at the specified index.

Parameters
