title: Symfony: question about get and set methods of the base model classes
body: <p>if you go to a base class of the model you won't find any get or set method. </p>
  
  <p>It is because those methods is said are created "on the air".</p>
  
  <p>What does it mean exacltly, I suspect it just means they are created in the moment they are needed.</p>
  
  <p>Am i right? What are the advantages of the way rescpect of generate the methods inside the base class?</p>
  
  <p>Regards</p>
