it.unibz.inf.ontop.injection.OntopSQLOWLAPIConfiguration getConfiguration()

close

void close()

Closes its connection to the in-memory DB that was kept just for keeping the DB alive. After calling this method, the loader is not RESPONSIBLE for keeping the DB alive anymore. This responsibility may be delegating to another object: the latter just need to keep a connection alive. An in-memory DB like H2 is dropped when no-one connects to it.
