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 |
||
10 | View Code Duplication | final class CartExistsValidator extends ConstraintValidator |
|
11 | { |
||
12 | /** |
||
13 | * @var OrderRepositoryInterface |
||
14 | */ |
||
15 | private $orderRepository; |
||
16 | |||
17 | /** |
||
18 | * @param OrderRepositoryInterface $orderRepository |
||
19 | */ |
||
20 | public function __construct(OrderRepositoryInterface $orderRepository) |
||
24 | |||
25 | /** |

26 | * {@inheritdoc} |
||
27 | */ |
||
28 | public function validate($token, Constraint $constraint) |
||
