Constructor Detail

GeoPkgExtension

protected GeoPkgExtension(String name,
                          String definition,
                          GeoPkgExtension.Scope scope,
                          GeoPackage geoPackage)

Creates a new geopackage extension. By itself, it only allows to access the associated tables.

Parameters:

name - The extension name, as registered with OGC

definition - The definition, normally a URL pointing to a spec

scope - The scope, read/write or write/only

geoPackage - The GeoPackage providing access to the contents of the file

Returns:

isRegistered

public boolean isRegistered()
                     throws IOException

Returns true if the extension has at least one registration in the geopkg_extensions table. If not registered, the GeoPackage does not really have this extension, but the class could be used to create one (this behavior is extension specific and delegated to sub-classes).
