			0 ignored issues – show Duplication introduced 2017-01-24 23:07 UTC by Report Bug Copy Issue Report This class seems to be duplicated in your project. Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...

			0 ignored issues – show Bug introduced 2017-01-25 00:42 UTC by Report Bug Copy Issue Report The method `getInstance` does only exist in `Comodojo\Cache\Drivers\M...\Cache\Drivers\PhpRedis`, but not in `Comodojo\Cache\Drivers\A...jo\Cache\Drivers\Vacuum`. It seems like the method you are trying to call exists only in some of the possible types. Let’s take a look at an example: class A { public function foo() { } } class B extends A { public function bar() { } } /** * @param A\|B $x / function someFunction($x) { $x->foo(); // This call is fine as the method exists in A and B. $x->bar(); // This method only exists in B and might cause an error. } Available Fixes Add an additional type-check: /* * @param A\|B $x / function someFunction($x) { $x->foo(); if ($x instanceof B) { $x->bar(); } } Only allow a single type to be passed if the variable comes from a parameter: function someFunction(B $x) { /* ... */ } Loading history...
