			0 ignored issues – show Bug introduced 2018-01-19 16:49 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Drupal\Core\Entity\EntityInterface` as the method `getFields()` does only exist in the following implementations of said interface: `Drupal\Core\Entity\ContentEntityBase`, `Drupal\Core\Entity\EditorialContentEntityBase`, `Drupal\Core\Entity\RevisionableContentEntityBase`, `Drupal\Tests\Core\Entity\EntityManagerTestEntity`, `Drupal\aggregator\Entity\Feed`, `Drupal\aggregator\Entity\Item`, `Drupal\block_content\Entity\BlockContent`, `Drupal\comment\Entity\Comment`, `Drupal\contact\Entity\Message`, `Drupal\content_moderatio...\ContentModerationState`, `Drupal\content_translati...estTranslatableNoUISkip`, `Drupal\content_translati...yTestTranslatableUISkip`, `Drupal\entity_test\Entity\EntityTest`, `Drupal\entity_test\Entity\EntityTestAdminRoutes`, `Drupal\entity_test\Entit...ityTestBaseFieldDisplay`, `Drupal\entity_test\Entity\EntityTestCache`, `Drupal\entity_test\Entit...TestCompositeConstraint`, `Drupal\entity_test\Entity\EntityTestComputedField`, `Drupal\entity_test\Entit...TestConstraintViolation`, `Drupal\entity_test\Entity\EntityTestConstraints`, `Drupal\entity_test\Entity\EntityTestDefaultAccess`, `Drupal\entity_test\Entity\EntityTestDefaultValue`, `Drupal\entity_test\Entity\EntityTestFieldMethods`, `Drupal\entity_test\Entity\EntityTestFieldOverride`, `Drupal\entity_test\Entity\EntityTestLabel`, `Drupal\entity_test\Entity\EntityTestLabelCallback`, `Drupal\entity_test\Entity\EntityTestMul`, `Drupal\entity_test\Entity\EntityTestMulChanged`, `Drupal\entity_test\Entit...tityTestMulDefaultValue`, `Drupal\entity_test\Entity\EntityTestMulLangcodeKey`, `Drupal\entity_test\Entity\EntityTestMulRev`, `Drupal\entity_test\Entity\EntityTestMulRevChanged`, `Drupal\entity_test\Entit...vChangedWithRevisionLog`, `Drupal\entity_test\Entity\EntityTestMulRevPub`, `Drupal\entity_test\Entit...TestMultiValueBasefield`, `Drupal\entity_test\Entity\EntityTestNew`, `Drupal\entity_test\Entity\EntityTestNoBundle`, `Drupal\entity_test\Entity\EntityTestNoId`, `Drupal\entity_test\Entity\EntityTestNoLabel`, `Drupal\entity_test\Entity\EntityTestNoUuid`, `Drupal\entity_test\Entity\EntityTestRev`, `Drupal\entity_test\Entity\EntityTestStringId`, `Drupal\entity_test\Entity\EntityTestViewBuilder`, `Drupal\entity_test\Entity\EntityTestWithBundle`, `Drupal\entity_test_revlo...yTestMulWithRevisionLog`, `Drupal\entity_test_revlo...tityTestWithRevisionLog`, `Drupal\entity_test_update\Entity\EntityTestUpdate`, `Drupal\field_collection\Entity\FieldCollectionItem`, `Drupal\file\Entity\File`, `Drupal\language_test\Entity\NoLanguageEntityTest`, `Drupal\media\Entity\Media`, `Drupal\menu_link_content\Entity\MenuLinkContent`, `Drupal\migrate_entity_te...tity\StringIdEntityTest`, `Drupal\node\Entity\Node`, `Drupal\shortcut\Entity\Shortcut`, `Drupal\taxonomy\Entity\Term`, `Drupal\user\Entity\User`. 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...
