MultidimensionalSubset

AMD: require(["esri/layers/support/MultidimensionalSubset"], (MultidimensionalSubset) => { /* code goes here */ });
ESM: import MultidimensionalSubset from "@arcgis/core/layers/support/MultidimensionalSubset.js";
Class: esri/layers/support/MultidimensionalSubset
Inheritance: MultidimensionalSubsetAccessor
Since: ArcGIS Maps SDK for JavaScript 4.25

A subset of multidimensional raster data created by slicing the data along defined variables and dimensions. Only dimensional slices that meet the multidimensionalSubset requirements will be available on a multidimensional ImageryLayer or ImageryTileLayer when the multiDimensionalSubset property is set on the layer. For example, if you have an ImageryLayer that contains 30 years of monthly precipitation data, and you only want to expose data for each January to see how precipitation has changed for that month, you can set the multiDimensionalSubset on the imagery layer.

When the multiDimensionalSubset is defined on a layer, the multidimensionalDefinition property of the ImageryTileLayer or the mosaicRule.multidimensionalDefinition of the ImageryLayer must be within the defined multidimensionalSubset, otherwise nothing will be displayed on the map or available for analysis.

Method Overview

Show inherited methods Hide inherited methods
Name Return Type Summary Class

Adds one or more handles which are to be tied to the lifecycle of the object.

Accessor

Creates a deep clone of the MultidimensionalSubset object.

MultidimensionalSubset
*

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product.

MultidimensionalSubset

Returns true if a named group of handles exist.

Accessor

Removes a group of handles owned by the object.

Accessor

Converts an instance of this class to its ArcGIS portal JSON representation.

Method Details

addHandles

Inherited
Method
addHandles(handleOrHandles, groupKey)
Inherited from Accessor

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.

clone

Method
clone(){MultidimensionalSubset}

Creates a deep clone of the MultidimensionalSubset object.

Returns
Type Description
MultidimensionalSubset A clone of the object that invoked this method.

fromJSON

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.

hasHandles

Inherited
Method
hasHandles(groupKey){Boolean}
Inherited from Accessor

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

Inherited
Method
removeHandles(groupKey)
Inherited from Accessor

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");

toJSON

Method
toJSON(){Object}

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.

Type Definitions

SubsetDimension

Type Definition
SubsetDimension Object

Dimension name and its extent or range computed from the subsetDefinitions and it is added to dimensions.

Properties
name String

The dimension name.

extent Number[]

The computed extent or ranges for the given dimension.
