jhomenet.dao
Class DAOFactory

java.lang.Object
  jhomenet.dao.DAOFactory

Direct Known Subclasses:

HibernateDAOFactory

public abstract class DAOFactory
extends java.lang.Object

Defines all DAOs and the concrete factories to get the conrecte DAOs.

Either use the DEFAULT to get the same concrete DAOFactory throughout your application, or a concrete factory by name, e.g. DAOFactory.HIBERNATE is a concrete HibernateDAOFactory.

Implementation: If you write a new DAO, this class has to know about it. If you add a new persistence mechanism, add an additional concrete factory for it to the enumeration of factories.

It probably wouldn't be a bad idea to move the DEFAULT setting into external configuration.
