    Detailed Description

    Preplanned map areas are specific work areas or major incident areas that are defined by an online map author. Each online map can contain several map areas. These can be provided in a list by the OfflineMapTask::preplannedMapAreas method.

    Each preplanned map area creates map content that is stored online.

    Download this map content by running a DownloadPreplannedOfflineMapJob.

    Create this job by passing the preplanned map area to the OfflineMapTask::downloadPreplannedOfflineMap method on the task.

    To successfully load a PreplannedMapArea the PreplannedMapArea::packagingStatus must be PreplannedPackagingStatus}{PreplannedPackagingStatus::Complete}.

    Member Function Documentation

    PreplannedMapArea::PreplannedMapArea(Esri::ArcGISRuntime::PortalItem *portalItem, QObject *parent = nullptr)

    Constructor that accepts a PortalItem (portalItem) and an optional parent.

    Use this constructor to create a preplanned map area instance with a portal item that is of type map area.

    [signal] void PreplannedMapArea::contentItemsCompleted(QUuid taskId, Esri::ArcGISRuntime::ImmutablePortalItemListModel *contentItems)

    Signal emitted when contentItems completes.

    • taskId - The task ID that this signal corresponds to.
    • contentItems - A list model containing the fetched content items.

    The returned ImmutablePortalItemListModel object has the PreplannedMapArea as its parent.

    This function was introduced in Esri::ArcGISRuntime 100.3.

    See also Returned QObjects Parenting.

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

    Signal emitted when the loadStatus changes for this object.

    See also Loadable.

    [override virtual] PreplannedMapArea::~PreplannedMapArea()


    Esri::ArcGISRuntime::Geometry PreplannedMapArea::areaOfInterest() const

    Returns the area of interest bounding the preplanned map area.

    The area of interest is returned as a Geometry which can be either an Envelope or a Polygon depending on how the online map was created.

    [override virtual] void PreplannedMapArea::cancelLoad()

    Reimplements: Loadable::cancelLoad().

    See Loadable.

    Esri::ArcGISRuntime::TaskWatcher PreplannedMapArea::contentItems()

    Starts a task to fetch the content items for this preplanned map area.

    This method populates an ImmutablePortalItemListModel with the content items for this preplanned area. The results of this operation are cached, so the same portal item instances will be returned with each subsequent call of this method.

    This method returns a TaskWatcher for the asynchronous operation.

    This function was introduced in Esri::ArcGISRuntime 100.3.

    [override virtual] void PreplannedMapArea::load()

    Reimplements: Loadable::load().

    See Loadable.

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

    Reimplements: Loadable::loadError() const.

    See Loadable.

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

    Reimplements: Loadable::loadStatus() const.

    See Loadable.

    Esri::ArcGISRuntime::PreplannedPackagingStatus PreplannedMapArea::packagingStatus() const

    Returns the publishing status of the online map area.

    This property allows you to check whether an online PreplannedMapArea is in a PreplannedPackagingStatus::Complete state and ready to be downloaded.

    There are four possible values:

    If you attempt to download a PreplannedMapArea that is not PreplannedPackagingStatus::Complete the DownloadPreplannedOfflineMapJob will fail with Error::errorType {Esri::ArcGISRuntime::ErrorType} {ErrorType::MappingPackagingNotComplete}.

    If you attempt to create a set of DownloadPreplannedOfflineMapParameters by calling OfflineMapTask::createDefaultDownloadPreplannedOfflineMapParameters from a PreplannedMapArea that is not PreplannedPackagingStatus::Complete, the operation will also fail with Error::errorType {Esri::ArcGISRuntime::ErrorType} {ErrorType::MappingPackagingNotComplete}.

    If the packaging status is PreplannedPackagingStatus::Processing you can check it again following these steps:

    This function was introduced in Esri::ArcGISRuntime 100.9.

    Esri::ArcGISRuntime::PortalItem *PreplannedMapArea::portalItem() const

    Returns the portal item that this preplanned map area was created from.

    [override virtual] void PreplannedMapArea::retryLoad()

    Reimplements: Loadable::retryLoad().

    See Loadable.

    Esri::ArcGISRuntime::OfflineMapUpdateCapabilities *PreplannedMapArea::updateCapabilities() const

    Describes what methods for obtaining updates are supported for this preplanned map area. This property will return an empty OfflineMapUpdateCapabilities until loaded.

    This function was introduced in Esri::ArcGISRuntime 100.6.0.
