			0 ignored issues – show Bug Best Practice introduced 2017-10-05 01:38 UTC by Report Bug Copy Issue Report The expression `return $pipelines` returns the type `array\|AmaTeam\Image\Proj...\Framework\Conversion[]` which is incompatible with the return type mandated by `AmaTeam\Image\Projection...ce::createConversions()` of `AmaTeam\Image\Projection\API\ConversionInterface`. In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName { /** @return string / public function getName(); } class Name { public $name; } class User implements HasName { /* @return string\|Name */ public function getName() { return new Name('foo'); // This is a violation of the ``HasName`` interface // which only allows a string value to be returned. } } Loading history...
