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 |
||
| 8 | class Component_number |
||
| 9 | extends AbstractComponent |
||
|
|
|||
| 10 | implements ValueComponentInterface, |
||
| 11 | DisableableComponentInterface, |
||
| 12 | FilterableComponentInterface, |
||
| 13 | ValidatableComponentInterface |
||
| 14 | { |
||
| 15 | public $component_type = 'number'; |
||
| 16 | |||
| 17 | public function default_model() |
||
| 35 | |||
| 36 | public function filter($v) |
||
| 40 | |||
| 41 | public function validation($v,&$e) |
||
| 58 | |||
| 59 | public function required_arguments() |
||
| 63 | |||
| 64 | public function get_template_path() |
||
| 68 | } |
