org.apache.ojb.broker.PersistenceBroker
PersistenceBroker declares a protocol for persisting arbitrary objects. A typical implementation might wrap an RDBMS access layer. @see org.apache.ojb.broker.core.PersistenceBrokerImpl @see org.apache.ojb.broker.core.PersistenceBrokerBean @author Thomas Mahler @version $Id: PersistenceBroker.java,v 1.30.2.6 2005/12/22 20:40:17 tomdz Exp $
