Examples of org.apache.ojb.broker.query.Criteria

org.apache.ojb.broker.query.Criteria
Persistent Criteria can be used to retrieve sets of objects based on their attributes Normally each attribute is ANDed together, an OR can be performed by creating a new PersistentCriteria and adding it.
Criteria are used, rather than a simple string, because they can be precompiled for efficiency. This code is based on stuff from COBRA - Java Object Persistence Layer Copyright (C) 1997, 1998 DB Harvey-George eMail: cobra@lowrent.org @author Jakob Braeuchi @version $Id: Criteria.java,v 1.45.2.5 2005/12/21 22:27:09 tomdz Exp $
