* {@internal Extends an upstream sniff to benefit from the properties contained therein. |
|
20
|
|
|
* The properties are lists of valid PHP magic function and method names, which |
|
21
|
|
|
* should be ignored for the purposes of this sniff. |
|
22
|
|
|
* As this sniff is not PHP version specific, we don't need access to the utility |
|
23
|
|
|
* methods in the PHPCompatibility\Sniff, so extending the upstream sniff is fine. |
|
24
|
|
|
* As the upstream sniff checks the same (and more, but we don't need the rest), |
|
25
|
|
|
* the logic in this sniff is largely the same as used upstream. |
|
26
|
|
|
* Extending the upstream sniff instead of including it via the ruleset, however, |
|
27
|
|
|
* prevents hard to debug issues of errors not being reported from the upstream sniff |
|
28
|
|
|
* if this library is used in combination with other rulesets.}} |
