DirectionsFeatureSet

Class: esri/tasks/support/DirectionsFeatureSet
Inheritance: DirectionsFeatureSet FeatureSet Accessor
Since: ArcGIS API for JavaScript 4.0

A FeatureSet that has properties specific to routing. The features property contains the turn by turn directions text and geometry of the route. The attributes for each feature provide information associated with the corresponding route segment. The following attributes are returned:

  • text - The direction text
  • length - The length of the route segment
  • time - The time to travel along the route segment
  • ETA - The estimated time of arrival at the route segment in the local time
  • maneuverType - The type of maneuver that the direction represents

Property Details

declaredClass Stringreadonly inherited
Since: ArcGIS API for JavaScript 4.7

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

displayFieldName String inherited

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 Boolean inherited

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 Extent

The extent of the route.

features Graphic[]

An array of graphics containing the directions.

Autocasts from Object[]
Since: ArcGIS API for JavaScript 4.1

Information about each field.

geometryType String

The geometry type of the FeatureSet. This value is always esriGeometryPolyline.

mergedGeometry Polyline

A single polyline representing the route.

queryGeometry Geometry inherited
Since: ArcGIS API for JavaScript 4.11

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.

routeId String

The ID of the route returned from the server.

routeName String

Name specified in RouteParameters.stops.

spatialReference SpatialReference inherited

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 Object[]

Lists additional information about the directions depending on the value of RouteParameters.directionsOutputType.

totalDriveTime Number

Actual drive time calculated for the route.

totalLength Number

The length of the route as specified in the units set in RouteParameters.directionsLengthUnits.

See also:
totalTime Number

The total time calculated for the route as specified in the units set in RouteParameters.directionsTimeAttribute.
