esri/layers/support/MultidimensionalSubset
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 Details
-
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();ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey 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
Methodclone(){MultidimensionalSubset} -
Creates a deep clone of the MultidimensionalSubset object.
ReturnsType Description MultidimensionalSubset A clone of the object that invoked this method.
-
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
jsonparameter 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.Parameterjson 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.
ReturnsType Description * Returns a new instance of this class.
-
hasHandles
InheritedMethodhasHandles(groupKey){Boolean}Inherited from Accessor -
Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns trueif 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"); }
-
Inherited from Accessor
-
Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handle-group"); obj.removeHandles("other-handle-group");
-
toJSON
MethodtoJSON(){Object} -
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
ReturnsType Description Object The ArcGIS portal JSON representation of an instance of this class.
