Multipoint

Property Overview

Property Details

cache Objectreadonly inherited

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 Stringreadonly inherited

Since: ArcGIS Maps SDK for JavaScript 4.7

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

extent Extentreadonly inherited

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

hasM Boolean inherited

Indicates if the geometry has M values.

hasZ Boolean inherited

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 Number[][]

An array of points.

spatialReference SpatialReferenceautocast inherited

The spatial reference of the geometry.

Default Value:WGS84 (wkid: 4326)

type Stringreadonly

The string value representing the type of geometry.

For Multipoint the type is always "multipoint".

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 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(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(){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(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.

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(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 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(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Removes a group of handles owned by the object.

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(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(index, point){Multipoint}

Updates the point at the specified index.

Parameters

index Number The index of the point in the points property.

point Point|Number[] Point geometry that specifies the new location.

Returns

Type	Description
Multipoint	Returns the updated Multipoint.

toJSON(){Object}inherited

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns

Type	Description
Object	The ArcGIS portal JSON representation of an instance of this class.
