    Detailed Description

    A ServiceAreaTask calculates areas that can be serviced (reached) from a given location. A network service area is a region that encompasses all street locations that can be accessed within a given distance or travel time from one or more facilities. For instance, the 10-minute service area for a facility includes all the street locations that can be reached within 10 minutes from that facility.

    The service area task works in an online connected scenario by using a transportation network that is published to ArcGIS Server as an online Network Analyst service area service. Esri also provides ready-to-use services, such as the Directions and Routing Services, which require authentication with an ArcGIS organizational account. In connected scenarios, provide a URL to the REST endpoint of the service, along with any necessary credentials.

    See also Loadable and Service Area REST API documentation.

    ServiceAreaTask::ServiceAreaTask(const QUrl &url, QObject *parent = nullptr)

    Constructor that takes a url to an NA service endpoint with an optional parent.

    ServiceAreaTask::ServiceAreaTask(const QUrl &url, Esri::ArcGISRuntime::Credential *credential, QObject *parent = nullptr)

    Constructor that takes a url to a secured NA service endpoint and a credential, with an optional parent.

    ServiceAreaTask::ServiceAreaTask(const QString &databasePath, const QString &networkName, QObject *parent = nullptr)

    Constructor that takes a databasePath and networkName, with an optional parent.

    This function was introduced in Esri::ArcGISRuntime 100.2.

    [signal] void ServiceAreaTask::createDefaultParametersCompleted(QUuid taskId, Esri::ArcGISRuntime::ServiceAreaParameters defaultParameters)

    Signal emitted after the createDefaultParameters asynchronous method completes.

    • taskId - The task ID of the asynchronous task.
    • defaultParameters - The generated default ServiceAreaParameters.

    [signal] void ServiceAreaTask::doneLoading(Esri::ArcGISRuntime::Error loadError)

    Signal emitted when this object is done loading.

    • loadError - Details about any error that may have occurred.

    Note: If there is a load error it will also be emitted on the errorOccurred signal.

    See also Loadable and Object.

    [signal] void ServiceAreaTask::loadStatusChanged(Esri::ArcGISRuntime::LoadStatus loadStatus)

    Signal emitted when the load status changes for this object.

    See also Loadable.

    [signal] void ServiceAreaTask::solveServiceAreaCompleted(QUuid taskId, Esri::ArcGISRuntime::ServiceAreaResult serviceAreaResult)

    Signal emitted after the solveServiceArea asynchronous method completes.

    • taskId - The task ID of the asynchronous task.
    • serviceAreaResult - The generated ServiceAreaResult.

    [override virtual] ServiceAreaTask::~ServiceAreaTask()

    Destructor.

    [override virtual] QString ServiceAreaTask::apiKey() const

    Reimplements: ApiKeyResource::apiKey() const.

    Returns the API key. See ApiKeyResource.

    This function was introduced in Esri::ArcGISRuntime 100.10.

    See also setApiKey().

    [override virtual] void ServiceAreaTask::cancelLoad()

    Reimplements: Loadable::cancelLoad().

    See Loadable.

    Esri::ArcGISRuntime::TaskWatcher ServiceAreaTask::createDefaultParameters()

    Creates default service area parameters from the service.

    The createDefaultParametersCompleted signal emits when the operation is complete, giving access to the resulting ServiceAreaParameters.

    [override virtual] Esri::ArcGISRuntime::Credential *ServiceAreaTask::credential() const

    Reimplements: RemoteResource::credential() const.

    Returns the security credential used to access the service area service.

    Only applicable if using an online service that is secured.

    [override virtual] void ServiceAreaTask::load()

    Reimplements: Loadable::load().

    See Loadable.

    [override virtual] Esri::ArcGISRuntime::Error ServiceAreaTask::loadError() const

    Reimplements: Loadable::loadError() const.

    See Loadable.

    [override virtual] Esri::ArcGISRuntime::LoadStatus ServiceAreaTask::loadStatus() const

    Reimplements: Loadable::loadStatus() const.

    See Loadable.

    [override virtual] Esri::ArcGISRuntime::RequestConfiguration ServiceAreaTask::requestConfiguration() const

    Reimplements: RemoteResource::requestConfiguration() const.

    Returns the RequestConfiguration in use by this task.

    See also setRequestConfiguration().

    [override virtual] void ServiceAreaTask::retryLoad()

    Reimplements: Loadable::retryLoad().

    See Loadable.

    Esri::ArcGISRuntime::ServiceAreaTaskInfo ServiceAreaTask::serviceAreaTaskInfo() const

    Returns the ServiceAreaTaskInfo for this ServiceAreaTask.

    Wait until this ServiceAreaTask is finished loading before attempting to obtain the ServiceAreaTaskInfo.

    [override virtual] void ServiceAreaTask::setApiKey(const QString &apiKey)

    Reimplements: ApiKeyResource::setApiKey(const QString &apiKey).

    Sets the API key to apiKey. See ApiKeyResource.

    This function was introduced in Esri::ArcGISRuntime 100.10.

    See also apiKey().

    [override virtual] void ServiceAreaTask::setRequestConfiguration(const Esri::ArcGISRuntime::RequestConfiguration &requestConfiguration)

    Reimplements: RemoteResource::setRequestConfiguration(const Esri::ArcGISRuntime::RequestConfiguration &requestConfiguration).

    Sets the configuration parameters used for network requests sent by this task to requestConfiguration.

    See also requestConfiguration().

    Esri::ArcGISRuntime::TaskWatcher ServiceAreaTask::solveServiceArea(const Esri::ArcGISRuntime::ServiceAreaParameters &serviceAreaParameters)

    Solves a service area with the given serviceAreaParameters.

    The ServiceAreaTask::solveServiceAreaCompleted signal emits when the operation is complete, giving access to the ServiceAreaResult.
