The Error object returned if an error occurred while loading.

Default Value:null

loadStatus Stringreadonly

Represents the status of a load operation.

Value	Description
not-loaded	The object's resources have not loaded.
loading	The object's resources are currently loading.
loaded	The object's resources have loaded without errors.
failed	The object's resources failed to load. See loadError for more details.

Possible Values:"not-loaded"|"loading"|"failed"|"loaded"

Default Value:not-loaded

loadWarnings Object[]readonly

A list of warnings which occurred while loading.

networkServiceUrl Stringreadonly

Returns the url of network server.

owner Stringreadonly

The portal user owner of the network. This portal user can perform administrive actions against the network.

parsedUrl Stringreadonly

Converts url to a url object

schemaGeneration Numberreadonly

The schema version of the network. Each version of the network introduces new features and capabilities. e.g. A utility network created with ArcGIS Pro 2.8 will have a schema generation version 5. While a UN created with ArcGIS Pro 2.6 will be version 4.

sourceJSON Object

spatialReference SpatialReference

The spatial reference of the network, defined at the creation of the network, usually from the service territory class.

title String

The name of the network as defined in the webmap spec. Represents the layer name of the network layer defined while sharing the webmap.

type Stringreadonly

The type of the dataset. Returns "utility" if the object represents a utility network or "trace" in case the network is a trace network.

Possible Values:"utility"|"trace"

Default Value:utility

Method Overview

Method Details

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.

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.

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.

own(handleOrHandles)inherited

Since: ArcGIS API for JavaScript 4.24

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.whenOnce(() => !view.updating)
  .then(() => {
    wkidSelect.disabled = false;
});

handle.remove();

// Assign a handle using own()
this.own(reactiveUtils.whenOnce(() => !view.updating)
  .then(() => {
    wkidSelect.disabled = false;
  }));

Parameter:

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.

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
});
