Examples of org.apache.ojb.broker.query.Criteria.addPathClass()

org.apache.ojb.broker.query.Criteria.addPathClass()
Add a hint Class for a path. Used for relationships to extents.
SqlStatment will use these hint classes when resolving the path. Without these hints SqlStatment will use the base class the relationship points to ie: Article instead of CdArticle. @param aPath the path segment ie: allArticlesInGroup @param aClass the Class ie: CdArticle @see org.apache.ojb.broker.QueryTest#testInversePathExpression()

        // a C called '_third' 
        crit = new Criteria();
        crit.addLike("name", name+"_%");
        crit.addEqualTo("ref.name", name+"_second_1");
        crit.addEqualTo("ref.ref.name", name+"_third");
        crit.addPathClass("ref", ObjB.class);
        crit.addPathClass("ref.ref", ObjC.class);
        q = QueryFactory.newQuery(ObjA.class, crit);
        result = broker.getCollectionByQuery(q);
        assertEquals(1, result.size());
