			0 ignored issues – show Bug introduced 2017-07-27 13:35 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `OpenStack\Common\Resource\ResourceInterface` as the method `enumerate()` does only exist in the following implementations of said interface: `OpenStack\BlockStorage\v2\Models\QuotaSet`, `OpenStack\BlockStorage\v2\Models\Snapshot`, `OpenStack\BlockStorage\v2\Models\Volume`, `OpenStack\BlockStorage\v2\Models\VolumeAttachment`, `OpenStack\BlockStorage\v2\Models\VolumeType`, `OpenStack\Common\Resource\OperatorResource`, `OpenStack\Compute\v2\Models\AvailabilityZone`, `OpenStack\Compute\v2\Models\Flavor`, `OpenStack\Compute\v2\Models\Host`, `OpenStack\Compute\v2\Models\Hypervisor`, `OpenStack\Compute\v2\Models\HypervisorStatistic`, `OpenStack\Compute\v2\Models\Image`, `OpenStack\Compute\v2\Models\Keypair`, `OpenStack\Compute\v2\Models\QuotaSet`, `OpenStack\Compute\v2\Models\Server`, `OpenStack\Identity\v2\Models\Catalog`, `OpenStack\Identity\v2\Models\Endpoint`, `OpenStack\Identity\v2\Models\Entry`, `OpenStack\Identity\v2\Models\Tenant`, `OpenStack\Identity\v2\Models\Token`, `OpenStack\Identity\v3\Models\Assignment`, `OpenStack\Identity\v3\Models\Catalog`, `OpenStack\Identity\v3\Models\Credential`, `OpenStack\Identity\v3\Models\Domain`, `OpenStack\Identity\v3\Models\Endpoint`, `OpenStack\Identity\v3\Models\Group`, `OpenStack\Identity\v3\Models\Policy`, `OpenStack\Identity\v3\Models\Project`, `OpenStack\Identity\v3\Models\Role`, `OpenStack\Identity\v3\Models\Service`, `OpenStack\Identity\v3\Models\Token`, `OpenStack\Identity\v3\Models\User`, `OpenStack\Images\v2\Models\Image`, `OpenStack\Images\v2\Models\Member`, `OpenStack\Metric\v1\Gnocchi\Models\Metric`, `OpenStack\Metric\v1\Gnocchi\Models\Resource`, `OpenStack\Metric\v1\Gnocchi\Models\ResourceType`, `OpenStack\Networking\v2\...ayer3\Models\FloatingIp`, `OpenStack\Networking\v2\...ns\Layer3\Models\Router`, `OpenStack\Networking\v2\...ps\Models\SecurityGroup`, `OpenStack\Networking\v2\...odels\SecurityGroupRule`, `OpenStack\Networking\v2\Models\InterfaceAttachment`, `OpenStack\Networking\v2\Models\LoadBalancer`, `OpenStack\Networking\v2\...adBalancerHealthMonitor`, `OpenStack\Networking\v2\...ls\LoadBalancerListener`, `OpenStack\Networking\v2\Models\LoadBalancerMember`, `OpenStack\Networking\v2\Models\LoadBalancerPool`, `OpenStack\Networking\v2\Models\LoadBalancerStat`, `OpenStack\Networking\v2\Models\LoadBalancerStatus`, `OpenStack\Networking\v2\Models\Network`, `OpenStack\Networking\v2\Models\Port`, `OpenStack\Networking\v2\Models\Quota`, `OpenStack\Networking\v2\Models\Subnet`, `OpenStack\ObjectStore\v1\Models\Account`, `OpenStack\ObjectStore\v1\Models\Container`, `OpenStack\ObjectStore\v1\Models\Object`. 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...
