title: Mapping a custom NHibernate class (like a view)
body: <p>I have several classes/mappings ... Its all working fine...
  Sometimes a create a view for better performance ...</p>
  
  <p>I´d like to know if it´s posible to create a special mapping without creating the DB view...</p>
  
  <p>Example, I have :</p>
  
  <pre><code>class Test
  {
    Test2 test2;
    string a;
  } 
  
  class Test2
  {
    Test3 test3;
    string x;
  } 
  
  class Test3
  {
    Test4 test4;
    string y;
  } 
  </code></pre>
  
  <p>I´d like to create a class/mapping (without creating a db view) like that:</p>
  
  <pre><code>class CustomTest
  {
     string test_a;
     string Test2_x;
     string Test2_y;
  }
  </code></pre>
  
  <p>Is it posible?</p>
