Class HibernateDAOFactory

java.lang.Object
  jhomenet.dao.DAOFactory
      jhomenet.dao.hibernate.HibernateDAOFactory

public class HibernateDAOFactory
extends DAOFactory

Returns Hibernate-specific instances of DAOs.

One of the responsiblities of the factory is to inject a Hibernate Session into the DAOs. You can customize the getCurrentSession() method if you are not using the default strategy, which simply delegates to Hibernates built-in "current Session" mechanism.

If for a particular DAO there is no additional non-CRUD functionality, we use an inner class to implement the interface in a generic way. This allows clean refactoring later on, should the interface implement business data access methods at some later time. Then, we would externalize the implementation into its own first-level class. We can't use anonymous inner classes for this trick because they can't extend or implement an interface and they can't include constructors.
