		0 ignored issues – show Bug introduced 2016-01-14 17:56 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Youshido\GraphQL\Type\TypeInterface` as the method `resolve()` does only exist in the following implementations of said interface: `Youshido\GraphQL\Introspection\DirectiveListType`, `Youshido\GraphQL\Introspection\DirectiveType`, `Youshido\GraphQL\Introspection\EnumValueListType`, `Youshido\GraphQL\Introspection\EnumValueType`, `Youshido\GraphQL\Introspection\FieldListType`, `Youshido\GraphQL\Introspection\FieldType`, `Youshido\GraphQL\Introspection\InputValueListType`, `Youshido\GraphQL\Introspection\InputValueType`, `Youshido\GraphQL\Introspection\InterfaceListType`, `Youshido\GraphQL\Introspection\MutationType`, `Youshido\GraphQL\Introspection\QueryListType`, `Youshido\GraphQL\Introspection\QueryType`, `Youshido\GraphQL\Introspection\SchemaType`, `Youshido\GraphQL\Introspection\TypeDefinitionType`, `Youshido\GraphQL\Type\ListType\AbstractListType`, `Youshido\GraphQL\Type\ListType\ListType`, `Youshido\GraphQL\Type\Object\AbstractEnumType`, `Youshido\GraphQL\Type\Ob...AbstractInputObjectType`, `Youshido\GraphQL\Type\Object\AbstractMutationType`, `Youshido\GraphQL\Type\Object\AbstractObjectType`, `Youshido\GraphQL\Type\Object\AbstractUnionType`, `Youshido\GraphQL\Type\Object\EnumType`, `Youshido\GraphQL\Type\Object\InputObjectType`, `Youshido\GraphQL\Type\Object\ObjectType`, `Youshido\Tests\DataProvider\UserType`, `Youshido\Tests\StarWars\Schema\DroidType`, `Youshido\Tests\StarWars\Schema\EpisodeEnum`, `Youshido\Tests\StarWars\Schema\HumanType`, `Youshido\Tests\StarWars\Schema\QueryType`, `Youshido\Tests\Type\Union\Schema\FirstType`, `Youshido\Tests\Type\Union\Schema\QueryType`, `Youshido\Tests\Type\Union\Schema\SecondType`, `Youshido\Tests\Type\Union\Schema\TestUnionType`. 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. Add the method to the interface: interface User { /** @return string / public function getPassword(); /* @return string */ public function getDisplayName(); } Loading history...
