This class seems to be duplicated in your project.
                                            

                                            
                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Duplicated code is one of the most pungent code smells. If you need to duplicate
the same code in three or more different places, we strongly encourage you to
look into extracting the code into a single class or operation.

It seems like you code against a specific sub-type and not the parent class Symfony\Component\Config...\Builder\NodeDefinition as the method children() does only exist in the following sub-classes of Symfony\Component\Config...\Builder\NodeDefinition: Symfony\Component\Config...der\ArrayNodeDefinition, Webcreate\Conveyor\Confi...\StrategyNodeDefinition, Webcreate\Conveyor\Confi...lder\TaskNodeDefinition, Webcreate\Conveyor\Confi...ansporterNodeDefinition. Maybe you want to instanceof check for one of these explicitly?
                                                                                                                                                                                                                                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Let’s take a look at an example:


abstract class User
{
    /** @return string */
    abstract public function getPassword();
}

class MyUser extends 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 sub-classes
of User which does not have a getDisplayName() method, the code will break.




Available Fixes


  1. Change the type-hint for the parameter:
    

    class AuthSystem
{
    public function authenticate(MyUser $user) { /* ... */ }
}

    

    

    2. 

  2. 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.'
            );
        }

    }
}

    

    

    3. 




 Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types
inside the if block in such a case.


  1. Add the method to the parent class:
    

    abstract class User
{
    /** @return string */
    abstract public function getPassword();

    /** @return string */
    abstract public function getDisplayName();
}
