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 |
||
17 | View Code Duplication | class IsBoolean extends AbstractPropertyValidator implements PropertyValidatorInterface |
|
18 | { |
||
19 | const DIC_NAME = 'BooleanValidator'; |
||
20 | const MESSAGE_TEMPLATE = '"%s" is not boolean'; |
||
21 | |||
22 | /** |
||
23 | * @inheritDoc |
||
24 | */ |
||
25 | 3 | public function isValid($property, JobEntityInterface $jobEntity) |
|
33 | } |
