Method Detail

isCorrectDatabaseImplementation

public boolean isCorrectDatabaseImplementation(DatabaseConnection conn)
                                        throws DatabaseException

Description copied from interface: Database

Is this AbstractDatabase subclass the correct one to use for the given connection.

Throws:

DatabaseException
