Class DAOFactory

java.lang.Object
  bexee.dao.DAOFactory

Direct Known Subclasses:

JDODAOFactory, MemoryDAOFactory

public abstract class DAOFactory

extends java.lang.Object

Abstract factory class for constructing various types of DAOFactory implementations, each factory supporting a different type of persistent storage implementation.

DAOFactory is an abstract class that is inherited and implemented by different concrete DAO factories to support storage implementation-specific access. The client can obtain a concrete DAO factory implementation such as MemoryDAOFactory and use it to obtain concrete DAOs that work with that specific storage implementation.
