Members

H.service.RoutingService8.CONFIG_KEY string staticconstant

The property name to use when specifying options for this service within the H.service.Platform.Options#servicesConfig.

Methods

addEventListener (type, handler, opt_capture, opt_scope) inherited

This method adds a listener for a specific event.

Note that to prevent potential memory leaks, you must either call removeEventListener or dispose on the given object when you no longer need it.

Name	Type	Description
type	string	The name of the event
handler	function	An event handler function
opt_capture	boolean	optional true indicates that the method should listen in the capture phase (bubble otherwise)
opt_scope	Object	optional An object defining the scope for the handler function

addOnDisposeCallback (callback, opt_scope) inherited

This method adds a callback which is triggered when the EventTarget object is being disposed.

Name	Type	Description
callback	function	The callback function.
opt_scope	Object	optional An optional scope for the callback function

calculateIsoline (params, onResult, onError)H.util.ICancelable

This method sends a "Calculate Isoline" request to the HERE Isoline Routing API v8 and calls the onResult callback function once the service response becomes available (providing a H.service.ServiceResult object) or the onError callback if a communication error occurred.

Please refer to the HERE Isoline Routing API v8 documentation for information on available parameters and the response object structure.

Name	Type	Description
params	H.service.ServiceParameters	Contains service parameters to be sent with the request.
onResult	function(H.service.ServiceResult)	A callback function to be called once the API provides a response to the request.
onError	function(Error)	A callback function to be called if a communication error occurs during the request.

Returns:

Type	Description
H.util.ICancelable	a handle that allows to cancel the request.

Example

let routingParams = {
 'routingMode': 'fast',
 'transportMode': 'car',
 'origin':'52.5,13.4',
 'range[type]': 'time',
 'range[values]': '900',
};

// Define a callback function to process the routing response
let onResult = function(result) {
  if (result.isolines.length) {
    result.isolines[0].polygons.forEach((polygon) => {
        // Create a linestring to use as a point source for the isoline
        const linestring = H.geo.LineString.fromFlexiblePolyline(polygon.outer);

        // Create a polygon and a marker representing the isoline
        const isolinePolygon = new H.map.Polygon(linestring, {
          style: { strokeColor: 'blue', lineWidth: 3 }
        });

        // Create a marker for the start point
        const isolineCenter = new H.map.Marker(result.departure.place.location);

        // Add the polygon and marker to the map
        map.addObjects([isolinePolygon, isolineCenter]);

        // Center and zoom the map so that the whole isoline polygon is
        // in the viewport
        map.getViewModel().setLookAtData({bounds: isolinePolygon.getBoundingBox()});
    });
  }
};

// Assumption: the platform is instantiated.
// Get an instance of the routing service
let router = platform.getRoutingService(null, 8);

// Call the Isoline Routing API to calculate an isoline
router.calculateIsoline(
  routingParams,
  onResult,
  console.error
);

calculateRoute (params, onResult, onError)H.util.ICancelable

This method sends a request to the Routing API v8 to calculate a route and calls the onResult callback function once the service response becomes available (providing a H.service.ServiceResult object) or the onError callback if a communication error occurred.

Please refer to the Routing API v8 documentation for information on available parameters and the response object structure.

Name	Type	Description
params	H.service.ServiceParameters	Contains service parameters to be sent with the request.
onResult	function(H.service.ServiceResult)	A callback function to be called once the API provides a response to the request.
onError	function(Error)	A callback function to be called if a communication error occurs during the request.

Returns:

Type	Description
H.util.ICancelable	a handle that allows to cancel the request.

dispatchEvent (evt) inherited

This method dispatches an event on the EventTarget object.

Name	Type	Description
evt	H.util.Event | string	An object representing the event or a string with the event name

dispose () inherited

This method removes listeners from the given object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners.

getUrl ()H.service.Url inherited

This method returns the configured service URL.

Returns:

Type	Description
H.service.Url

removeEventListener (type, handler, opt_capture, opt_scope) inherited

This method removes a previously added listener from the EventTarget instance.

Name	Type	Description
type	string	The name of the event
handler	function	A previously added event handler
opt_capture	boolean	optional true indicates that the method should listen in the capture phase (bubble otherwise)
opt_scope	Object	optional An object defining the scope for the handler function
