// Print the number of polyline barriers.
const routeLayer = new RouteLayer({
  portalItem: {
    id: "69569b47b1e445b8a42ec12feab41ce9"
  }
});
await routeLayer.load();

const count = routeLayer.polylineBarriers.length;
console.log(`The route contains ${count} linear barriers`);
// output: "The route contains 2 linear barriers"

// Zoom to first barrier
view.goTo(routeLayer.polylineBarriers[0].geometry)

fromGraphic

static Method

Signature: fromGraphic (graphic: Graphic): PolylineBarrier

Since: ArcGIS Maps SDK for JavaScript 4.24

Creates a PolylineBarrier from the parsed Graphic. The method assumes that the graphic's attributes conform to the route layer item schema.

Parameters

Parameter	Type	Description	Required
graphic	`Graphic`	A Graphic instance.

Returns: PolylineBarrier
A PolylineBarrier instance.

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

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.

Parameters

Parameter	Type	Description	Required
json	`any`	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: any
Returns a new instance of this class.

clone

inherited Method

Signature: clone (): this

Inherited from: ClonableMixin

Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.

Returns: this
A deep clone of the class instance that invoked this method.

toGraphic

Method

Signature: toGraphic (): Graphic

Since: ArcGIS Maps SDK for JavaScript 4.24

Creates a Graphic from the PolylineBarrier instance. The resulting graphic will have attributes that conform to the route layer item schema.

Returns: Graphic
A Graphic instance.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
