    Detailed Description

    A GeoPackage is a platform-independent SQLite database file that contains the GeoPackage data and metadata tables.

    Member Function Documentation

    GeoPackage::GeoPackage(const QString &path, QObject *parent = nullptr)

    Constructor that takes a path to a GeoPackage file along with an optional parent.

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

    Signal emitted when the loadStatus property changes.

    See also Loadable.

    [override virtual] GeoPackage::~GeoPackage()

    Destructor

    [override virtual] void GeoPackage::cancelLoad()

    Reimplements: Loadable::cancelLoad().

    See Loadable.

    void GeoPackage::close()

    Close the GeoPackage.

    This should only be called once you have finished accessing the data in the GeoPackage. For example: remove feature layers and rasters from maps and release feature tables. Attempts to access a GeoPackage after it is closed will fail, resulting in an error. After closing a GeoPackage, the underlying file it references can be deleted.

    QList<Esri::ArcGISRuntime::GeoPackageFeatureTable *> GeoPackage::geoPackageFeatureTables() const

    Returns all the feature tables from the GeoPackage.

    QList<Esri::ArcGISRuntime::GeoPackageRaster *> GeoPackage::geoPackageRasters() const

    Returns all the rasters from the GeoPackage.

    [override virtual] void GeoPackage::load()

    Reimplements: Loadable::load().

    See Loadable.

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

    Reimplements: Loadable::loadError() const.

    See Loadable.

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

    Reimplements: Loadable::loadStatus() const.

    See Loadable.

    QString GeoPackage::path() const

    The path specified to the GeoPackage file.

    [override virtual] void GeoPackage::retryLoad()

    Reimplements: Loadable::retryLoad().

    See Loadable.
