Extensions (GeoPackage Core 3.0.0 API)

java.lang.Object
- mil.nga.geopackage.extension.Extensions

```
public class Extensions
extends Object
```
Indicates that a particular extension applies to a GeoPackage, a table in a GeoPackage or a column of a table in a GeoPackage. An application that access a GeoPackage can query the gpkg_extensions table instead of the contents of all the user data tables to determine if it has the required capabilities to read or write to tables with extensions, and to “fail fast” and return an error message if it does not.
