it.unibz.inf.ontop.answering.connection.impl

Class SQLConnection

java.lang.Object

it.unibz.inf.ontop.answering.connection.impl.SQLConnection

All Implemented Interfaces:

OBDAConnection, OntopConnection, AutoCloseable

public class SQLConnection
extends Object
implements OntopConnection

Quest connection is responsible for wrapping a JDBC connection to the data source. It will translate calls to OBDAConnection into JDBC Connection calls (in most cases directly). SQL-specific implementation (specific to the JDBCConnector)! TODO: rename it SQLQuestConnection
