use Doctrine\ORM\Mapping as ORM;
use Lzakrzewski\FacebookAuthenticationBundle\Model\FacebookUser;

/**
 * @ORM\Entity
 * @ORM\Table(name="users")
 */
class User extends BaseUser implements FacebookUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="bigint", nullable=true)
     */
    private $facebookId;

    /** {@inheritdoc} */
    public function getFacebookId()
    {
        return $this->facebookId;
