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 |
||
5 | class Result |
||
6 | { |
||
7 | private $size; |
||
8 | private $duration; |
||
9 | private $hasSolution; |
||
10 | |||
11 | /** |
||
12 | * @param int $size |
||
13 | * @param int $duration |
||
14 | * @param bool $hasSolution |
||
15 | */ |
||
16 | public function __construct($size, $duration, $hasSolution) |
||
22 | |||
23 | public function getSize() |
||
27 | |||
28 | public function getDuration() |
||
32 | |||
33 | public function hasSolution() |
||
37 | |||
38 | View Code Duplication | private function filterSize($size) |
|
48 | |||
49 | View Code Duplication | private function filterDuration($duration) |
|
59 | |||
60 | private function filterHasSolution($hasSolution) |
||
64 | } |
