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.
