Property Details
The cache is used to store values computed from geometries that need to cleared or recomputed upon mutation. An example is the extent of a polygon.
- Since: ArcGIS API for JavaScript 4.7
The name of the class. The declared class name is formatted as
esri.folder.className
.
The extent of the geometry. For a point, the extent is null.
Indicates if the geometry has M values.
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.
An array of points.
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 Details
- addPoint(point){Multipoint}
Adds a point to the Multipoint.
Parameter: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 a product in the ArcGIS platform. 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 ObjectA 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 NumberThe index of the point in the points property.
Returns:Type Description Point The point at the specified index.
- removePoint(index){Point}
Removes a point from the Multipoint. The index specifies which point to remove.
Parameter:index NumberThe 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 NumberThe index of the point in the points property.
Point geometry that specifies the new location.
Returns:Type Description Multipoint Returns the updated Multipoint.
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.
