Examples of org.apache.torque.util.Criteria.addJoin()

org.apache.torque.util.Criteria.addJoin()
This is the way that you should add a join of two tables. For example:
AND PROJECT.PROJECT_ID=FOO.PROJECT_ID
left = PROJECT.PROJECT_ID right = FOO.PROJECT_ID @param left A String with the left side of the join. @param right A String with the right side of the join. @return A modified Criteria object.

        Criteria criteria = new Criteria();
        criteria.add(UserGroupRolePeer.USER_ID,
                ((Persistent) user).getPrimaryKey());
        criteria.add(UserGroupRolePeer.GROUP_ID,
                ((Persistent) group).getPrimaryKey());
        criteria.addJoin(UserGroupRolePeer.ROLE_ID, RolePeer.ROLE_ID);
        return retrieveSet(criteria);
    }

                     user.getName());


        criteria.add(TurbineUserGroupRolePeer.GROUP_ID,

        criteria.addJoin(UserPeerManager.getIdColumn(),
