			0 ignored issues – show Bug introduced 2018-09-10 22:47 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Railt\Parser\Ast\RuleInterface` as the method `getFullName()` does only exist in the following implementations of said interface: `Railt\SDL\Frontend\Ast\D...\ArgumentDefinitionNode`, `Railt\SDL\Frontend\Ast\D...DirectiveDefinitionNode`, `Railt\SDL\Frontend\Ast\D...tion\EnumDefinitionNode`, `Railt\SDL\Frontend\Ast\D...EnumValueDefinitionNode`, `Railt\SDL\Frontend\Ast\D...ion\FieldDefinitionNode`, `Railt\SDL\Frontend\Ast\D...ion\InputDefinitionNode`, `Railt\SDL\Frontend\Ast\D...nputFieldDefinitionNode`, `Railt\SDL\Frontend\Ast\D...InterfaceDefinitionNode`, `Railt\SDL\Frontend\Ast\D...on\ObjectDefinitionNode`, `Railt\SDL\Frontend\Ast\D...on\ScalarDefinitionNode`, `Railt\SDL\Frontend\Ast\D...on\SchemaDefinitionNode`, `Railt\SDL\Frontend\Ast\D...hemaFieldDefinitionNode`, `Railt\SDL\Frontend\Ast\D...tion\TypeDefinitionNode`, `Railt\SDL\Frontend\Ast\D...ion\UnionDefinitionNode`. 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.
