			0 ignored issues – show Bug introduced 2018-05-24 14:00 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `RDS\Hydrogen\Criteria\CriterionInterface` as the method `getQuery()` does only exist in the following implementations of said interface: `RDS\Hydrogen\Criteria\Group`, `RDS\Hydrogen\Criteria\Relation`. Let’s take a look at an example: interface User { /** @return string / public function getPassword(); } class MyUser implements User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.

			0 ignored issues – show Comprehensibility Bug introduced 2018-05-24 14:00 UTC by Report Bug Copy Issue Report It seems like you call parent on a different method (`getDoctrineExpression()` instead of `apply()`). Are you sure this is correct? If so, you might want to change this to `$this->getDoctrineExpression()`. This check looks for a call to a parent method whose name is different than the method from which it is called. Consider the following code: class Daddy { protected function getFirstName() { return "Eidur"; } protected function getSurName() { return "Gudjohnsen"; } } class Son { public function getFirstName() { return parent::getSurname(); } } The `getFirstName()` method in the `Son` calls the wrong method in the parent class.
