Symfony2 User Entity change class variables - variables

Question

simple question but i don't know how to do it.
As an example we have User Entity for login (class below), how can i change $password to $accountPass ? Ofcourse it means that all relationships must be applied as it is $password, and all symfony2 classes must understand that variable (old) $password now is (changed to) $accountPass.
Question is about "names of variables"... Anyone know how to deal with it?
User Entity :
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* #ORM\Entity()
* #ORM\Table(name="_account")
* #UniqueEntity("username")
*/
class User implements UserInterface
{
public function __construct()
{
$this->salt = md5(uniqid(null, true));
$this->isActive = true;
}
/**

*
* #return string
*/
public function getRoles()
{
return array('ROLE_USER');
}
/**
*
*
* #return
*/
public function eraseCredentials()
{
}
/**
* Get equals
*
* #return boolean
*/
public function equals(UserInterface $user)
{
return $user->getUsername() == $this->getUsername();
}
/**

return $this;

/**

public function getUsername()
{
return $this->username;

You have to map all fields in your Entity class and name them as you want to.

Answer 2

/**
* #var string
*
* #ORM\Column(name="password", type="string", length=255)
*/
protected $accountPass;
public function setPassword($password)
{
$this->accountPass = $password;
return $this;
}
/**
* Get password
*
* #return string
*/
public function getPassword()
{
return $this->accountPass;
}
It should be obvious of course that when you change the method name, that other classes have no way of knowing this!
All occurrences of the old method name should be changed to!
But I don't really see why you would this?
