    Detailed Description

    Use a RouteTask to find the best way to get from one location to another or to visit several locations. A route task is a network analysis task that solves a routing problem defined in a RouteParameters instance, using data in a transportation network dataset. The task calculates the route between a series of locations, known as stops. A route task is executed asynchronously. A successful execution returns a RouteResult instance with details about the route.

    When working in an online connected scenario, the transportation network can be published to ArcGIS Server as an online Network Analyst routing service. Esri also provides ready-to-use services, such as the Directions and Routing Services, which requires authentication with an ArcGIS organizational account. In connected scenarios, provide a URL to the REST endpoint of the service, along with any necessary credentials.

    When working offline in a disconnected scenario, the transportation network can be exported as a Runtime-enabled network from either ArcMap or ArcGIS Pro. If you are using ArcMap, run the Create Runtime Content geoprocessing tool, and reference a map document that contains the network dataset you want to export. This will output a mobile geodatabase (*.geodatabase), and a transportation network folder (*.tn). Create route task by loading the mobile geodatabase and transportation network folder onto the device, setting the URL property to a local path to the mobile geodatabase that contains the network, and setting the networkName property to the name of the network dataset. If you are using ArcGIS Pro, run the Create Mobile Map Package geoprocessing tool, and select the map and network dataset that you wish to export. The output is a mobile map package (*.mmpk) which is a compressed file containing everything needed to use the route task offline. To solve network analyst routes, load a mobile map package onto your device, extract the map from the package, and access the transportation network from each map. Each transportation networks contain the geodatabase and the network name needed to execute a route task.

    An example of an online RouteTask:

    RouteTask {
        id: onlineRouteTask
        url: "https://www.myServer.com/arcgis/rest/services/routing/NAServer/Route"
    }

    And for offline routing a local path is provided along with a network name:

    RouteTask {
        id: offlineRouteTask
        url: "file:///Users/<username>/routing.geodatabase"
        networkName: "Streets_ND"
    }

    Note: The url and transportationNetworkDataset properties should not both be assigned. A RouteTask may be initialized from one or the other, but not both. In the event that both are assigned, the last one assigned takes precedence and will be used to initialize the RouteTask.

    This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
