Example

const [WebMap, MapView, esriConfig] = await $arcgis.import([
  "@arcgis/core/WebMap.js",
  "@arcgis/core/views/MapView.js",
  "@arcgis/core/config.js"
]);

// set the hostname to the portal instance
esriConfig.portalUrl = "https://myHostName.domain.com/arcgis";

const webMap = new WebMap({
  portalItem: {
    id: "webmapID"
  }
});

const mapView = new MapView({
  map: webMap
});

webMap.when(async () => {
  // check if webMap contains utility networks
  if (webMap.utilityNetworks.length > 0) {
    // assign the utility network at index 0
    utilityNetwork = webMap.utilityNetworks.at(0);

    // trigger the loading of the UtilityNetwork instance
    await utilityNetwork.load();

    // Print the subnetworks table service url and id
    console.log(`Dirty areas layer id: ${utilityNetwork.networkSystemLayers.subnetworksTableId}`);
    console.log(`Dirty areas layer url: ${utilityNetwork.networkSystemLayers.subnetworksTableUrl}`);

associationsTable

readonly Property

Type: FeatureLayer | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.32

A FeatureLayer representing the associations table. This layer is only loaded as needed, so the property has a default value of null. It can be set by calling the loadAssociationsTable() method.

associationsTableId

readonly Property

Type: number | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.29

associationsTableUrl

readonly Property

Type: string | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.29

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

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

dirtyAreasLayerId

readonly Property

Type: number | null | undefined

The layer ID of the service containing the utility network's dirty areas.

dirtyAreasLayerUrl

readonly Property

Type: string | null | undefined

The service url containing the utility network's dirty areas.

rulesTableId

readonly Property

Type: number | null | undefined

The layer ID of the service containing the network rules table.

rulesTableUrl

readonly Property

Type: string | null | undefined

The service url containing the network rules table.

subnetworksTable

readonly Property

Type: FeatureLayer | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.34

A FeatureLayer representing the subnetworks table. This layer is only loaded as needed, so the property has a default value of null. It can be set by calling the loadSubnetworksTable() method.

subnetworksTableId

readonly Property

Type: number | null | undefined

The layer ID of the service containing the utility network's Subnetworks table. The Subnetworks table contains the information about all the existing and deleted subnetworks in a utility network.

subnetworksTableUrl

readonly Property

Type: string | null | undefined

The service url containing the utility network's Subnetworks table.
