title: Hibernate Criteria API equivalent to HQL select clause?
body: <p>I'd like to have a combined query for two persistent classes.</p>
  
  <p>In HQL this could be achieved by the select clause,</p>
  
  <pre><code>select new Family(mother, mate, offspr)
      from DomesticCat as mother
          join mother.mate as mate
          left join mother.kittens as offspr
  </code></pre>
  
  <p>In the above example, Family is a conbined class with DemesticCat as its construtor params</p>
  
  <p>What is the Criteria equivalent of the HQL select clause ?</p>
