Example

// Utility network service url
const networkServiceUrl = "https://myserver.esri.com/server/rest/services/NapervilleElectric/UtilityNetworkServer";

// Define the QueryAssociationsParameters
const queryAssociationsParameters = new QueryAssociationsParameters({
  associationTypes: ["containment", "attachment", "junction-edge-from-connectivity"],
  elements: [
    {
      networkSourceId: 2,
      globalId: "{46B3FA19-2237-4D38-A7CF-AA34C3T40420}",
      objectId: 44,
      terminalId: 1,
      assetGroupCode: 1,
      assetTypeCode: 1
    },
    {
      networkSourceId: 9,
      globalId: "{321C0089-1165-42D9-K45B-ED91B1A40500}",
      objectId: 45,
      terminalId: 1,
      assetGroupCode: 13,
      assetTypeCode: 441
    }
 ]
});

// Query associations, and assign the query result to a variable of type QueryAssociationsResult
const queryAssociationsResult = await queryAssociations(networkServiceUrl, queryAssociationsParameters);

// Print out the first association
console.log(queryAssociationsResult.associations[0]);

Junction-edge connectivity associations are used to establish a relationship between a point feature or junction object and an edge object.

Junction-edge from connectivity
Junction-edge midspan connectivity
Junction-edge to connectivity

These association types enable connectivity to be established between nonspatial junction and edge objects and provide an additional method to model connectivity between noncoincident point features using an edge object.

Possible Values

Value	Description
connectivity	Allows modeling the connectivity between two features that are not coincident or between spatial features and nonspatial junction and edge objects.
junction-junction-connectivity	Allows modeling the connectivity between two features that are not coincident or between spatial features and nonspatial junction and edge objects.
attachment	Allows the modeling of supporting structures and attachments in a network.
containment	Allows a dense collection of features to be represented by a single feature.
junction-edge-from-connectivity	Junction edge from connectivity.
junction-midspan-connectivity	Junction edge midspan connectivity.
junction-edge-to-connectivity	Junction edge to connectivity.

The "connectivity" type has been deprecated since version 4.29. Please use "junction-junction-connectivity" instead.

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
*	Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product.	QueryAssociationsParameters
Boolean	Returns true if a named group of handles exist.	Accessor
	Removes a group of handles owned by the object.	Accessor
Object	Converts an instance of this class to its ArcGIS portal JSON representation.	QueryAssociationsParameters

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.

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 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 Inherited Method removeHandles(groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 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");

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.
