UML Class diagram - Criteria persistence framework

The picture shows a class diagram of a portion of a persistence subsystem. Here you can see the classes involved in the search for entities in a relational database. You can view different search criteria as CompositeCriterioBinary and her 2 daughters classes "AND" and "OR". This approach generates the WHERE part of the SQL query. You can also see the "OrderCriterio" class which allows for the entities ordered by some of its attributes.
