DirectionsFeatureSet | API Reference | ArcGIS Maps SDK for JavaScript 4.31

DirectionsFeatureSet is a subclass of FeatureSet that contains street directions for a solved route.

DirectionsFeatureSet is only returned when a route is solved with an directions output type of "complete", "complete-no-events", "instructions-only", "standard", or "summary-only". The "featuresets" output type returns two regular FeatureSet, one for events, and the other for the path in-between events.

Example

// Get the drive time between Esri and the Redlands Bowl
const apiKey = "<ENTER YOUR API KEY HERE>";
const url = "https://route-api.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World";

const spatialReference = SpatialReference.WebMercator;

const stops = new Collection([
  new Stop({
    name: "Esri",
    geometry: new Point({ x: -13046165, y: 4036335, spatialReference })
  }),
  new Stop({
    name: "Redland Bowl",
    geometry: new Point({ x: -13045111, y: 4036114, spatialReference })
  })
]);

const routeParameters = new RouteParameters({
  apiKey,
  stops,
  outSpatialReference: spatialReference,
  returnDirections: true,
  directionsOutputType: "standard" // default value
});

const { routeResults } = await route.solve(url, routeParameters);
const { directions } = routeResults[0];
console.log(`The total drive time is: ${directions.totalTime}`);

Property Details

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

displayFieldName Inherited Property displayFieldName String Inherited from FeatureSet

The name of the layer's primary display field. The value of this property matches the name of one of the fields of the feature. This is only applicable when the FeatureSet is returned from a task. It is ignored when the FeatureSet is used as input to a geoprocessing task.

exceededTransferLimit Inherited Property exceededTransferLimit Boolean Inherited from FeatureSet

Typically, a layer has a limit on the number of features (i.e., records) returned by the query operation. If maxRecordCount is configured for a layer, exceededTransferLimit will be true if a query matches more than the maxRecordCount features. It will be false otherwise. Supported by ArcGIS Server version 10.1 and later.

extent Property extent Extent

The extent of the route.

features Property features Graphic[]

An array of direction features. The features are of type DirectionsFeature.

fields Inherited Property fields Field[]autocast Inherited from FeatureSet Autocasts from Object []

Information about each field.

geometryType Property geometryType String

The geometry type of the Directions FeatureSet.

For DirectionsFeatureSet the geometryType is always "polyline".

mergedGeometry Property mergedGeometry Polyline

A single polyline representing the route.

queryGeometry Inherited Property queryGeometry Geometry Inherited from FeatureSet

The geometry used to query the features. It is useful for getting the buffer geometry generated when querying features by distance or getting the query geometry projected in the outSpatialReference of the query. The query geometry is returned only for client-side queries and hosted feature services. The query's returnQueryGeometry must be set to true and the layer's capabilities.query.supportsQueryGeometry has to be true for the query to return query geometry.

Query.returnQueryGeometry

routeId Property routeId Number

The ID of the route.

routeName Property routeName String

The name of the route.

spatialReference Inherited Property spatialReference SpatialReference Inherited from FeatureSet

When a FeatureSet is used as input to Geoprocessor, the spatial reference is set to the map's spatial reference by default. This value can be changed. When a FeatureSet is returned from a task, the value is the result as returned from the server.

strings Property strings DirectionsString[]

A flattened array of all direction strings.

totalDriveTime Property totalDriveTime Number

The total drive time for the route. Temporal units are defined by RouteParameters.directionsTimeAttribute in a route solve request.

totalLength Property totalLength Number

The total length of the route. Length units are defined by RouteParameters.directionsLengthUnits in a route solve request.

See also

RouteParameters.directionsLengthUnits

totalTime Property totalTime Number

The total time for the route including wait and service time. Temporal units are defined by RouteParameters.directionsTimeAttribute in a route solve request.

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.	FeatureSet
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.	FeatureSet

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 Inherited 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 Inherited Method toJSON(){Object} Inherited from FeatureSet

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.
