    void 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.

    void retryLoad()
