Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS API for JavaScript 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 }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);

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.

cancelLoad()

Cancels a load() operation if it is already in progress.

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.

fromPortalItem(params){Promise<UtilityNetwork>}static

Creates a new network instance from an ArcGIS Online or ArcGIS Enterprise portal item.

Known Limitations This method does not populate the sharedNamedTraceConfigurations for a UtilityNetwork instance.

Parameters

params Object The parameters for loading the portal item. Specification portalItem PortalItem The object representing an ArcGIS Online or ArcGIS Enterprise portal item from which to load the network.

Returns

Type	Description
Promise<UtilityNetwork>	Returns a promise which resolves to the new utility network instance.

Example

// Create a utility network from a specified portal item that contains a utility network feature service
const item = new PortalItem({
  id: "77c7ae75eb3e4e08a7ad98cb37fefe88",
});

const utilityNetwork = await UtilityNetwork.fromPortalItem(item);

await utilityNetwork.load();
console.log("utilityNetwork loaded? ", utilityNetwork.loadStatus);

getLayerIdBySourceId(id){Number}

The network consists of sources (classes) and each source has a unique Id. These source Ids are used to perform traversal in the network topology. The trace end points are not aware of layers and only returns sources of results. This method returns the layerId for given a source Id. Used as a helper method to process trace results.

Parameter

id Number The id of the source.

Returns

Type	Description
Number	The layer id.

hasHandles(groupKey){Boolean}inherited

Since: ArcGIS API for JavaScript 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");
}

isFulfilled(){Boolean}

isFulfilled() may be used to verify if creating an instance of the class is fulfilled (either resolved or rejected). If it is fulfilled, true will be returned.

Returns

Type	Description
Boolean	Indicates whether creating an instance of the class has been fulfilled (either resolved or rejected).

isRejected(){Boolean}

isRejected() may be used to verify if creating an instance of the class is rejected. If it is rejected, true will be returned.

Returns

Type	Description
Boolean	Indicates whether creating an instance of the class has been rejected.

isResolved(){Boolean}

isResolved() may be used to verify if creating an instance of the class is resolved. If it is resolved, true will be returned.

Returns

Type	Description
Boolean	Indicates whether creating an instance of the class has been resolved.

load(){Promise}

Triggers the loading of the network instance.

Fully loads the network definition and all related objects (e.g. trace configurations)

Returns

Type	Description
Promise	Resolves when the Network is loaded.

load(signal){Promise}

Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance.

This method must be called by the developer when accessing a resource that will not be loaded in a View.

The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.

It's possible to provide a signal to stop being interested into a Loadable instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.

Parameter

signal AbortSignal optional Signal object that can be used to abort the asynchronous task. The returned promise will be rejected with an Error named AbortError when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.

Returns

Type	Description
Promise	Resolves when the resources have loaded.

queryNamedTraceConfigurations(query, options){Promise<NamedTraceConfiguration[]>}

Since: ArcGIS API for JavaScript 4.25

Named trace configurations allow you to add and store complex traces in a network that can be shared across an organization through web maps and consumed by web and field applications. This method returns a list of NamedTraceConfiguration objects that meet specific search conditions. Used to find existing named trace configurations in a utility network.

Parameters

query Object optional The query parameters that are used to determine which named trace configurations will be returned. Specification creators String[] optional An array of the named trace configuration creators to be queried. globalIds String[] optional An array of named trace configuration globalIds (UUID) to be queried. names String[] optional An array of named trace configuration names to be queried. tags String[] optional An array of named trace configuration user tags to be queried.

options RequestOptions optional The request options specified by the user in the data request. See RequestOptions for available properties.

Returns

Type	Description
Promise<NamedTraceConfiguration[]>	Resolves with an array of named trace configurations filtered based on the query parameters.

Examples

// Initialize the query object with global IDs of the named trace configurations to query.
const query = {
  globalIds: ["5dbb5a13-ab2f-452d-bfcb-6f98154ccb9d", "cf568e46-f200-486c-adb1-d008a3da0ed1"],
}

// Query the utility network named trace configurations
// and filter the results by the query object.
const namedTraceConfigurations = await utilityNetwork.queryNamedTraceConfigurations(query);

// Print the named trace configurations to the console.
console.log(namedTraceConfigurations)

// Calling this method without parameters returns all named trace configurations in the utility network.
const namedTraceConfigurations = await utilityNetwork.queryNamedTraceConfigurations();

// Print all the named trace configurations to the console.
console.log(namedTraceConfigurations);

removeHandles(groupKey)inherited

Since: ArcGIS API for JavaScript 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(){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.

when(callback, errback){Promise}

when() may be leveraged once an instance of the class is created. This method takes two input parameters: a callback function and an errback function. The callback executes when the instance of the class loads. The errback executes if the instance of the class fails to load.

Parameters

callback Function optional The function to call when the promise resolves.

errback Function optional The function to execute when the promise fails.

Returns

Type	Description
Promise	Returns a new promise for the result of callback that may be used to chain additional functions.

Example

// Although this example uses MapView, any class instance that is a promise may use when() in the same way
let view = new MapView();
view.when(function(){
  // This function will execute once the promise is resolved
}, function(error){
  // This function will execute if the promise is rejected due to an error
});
