Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 11 | View Code Duplication | final class TokenIsNotUsedValidator extends ConstraintValidator |
|
| 12 | { |
||
| 13 | /** |
||
| 14 | * @var OrderRepositoryInterface |
||
| 15 | */ |
||
| 16 | private $orderRepository; |
||
| 17 | |||
| 18 | /** |
||
| 19 | * @param OrderRepositoryInterface $orderRepository |
||
| 20 | */ |
||
| 21 | public function __construct(OrderRepositoryInterface $orderRepository) |
||
| 25 | |||
| 26 | /** |
||
| 27 | * {@inheritdoc} |
||
| 28 | */ |
||
| 29 | public function validate($token, Constraint $constraint) |
||
| 35 | } |
