 over again: it only generates getters and setters that don't exist (i.e. it
 doesn't replace your existing methods).

 .. note::
 
     Doctrine doesn't care whether your properties are ``protected`` or ``private``,
     or whether or not you have a getter or setter function for a property.
     The getters and setters are generated here only because you'll need them
     to interact with your PHP object.
