How to fix   Duplicated Code    Complexity   

Duplicated Code

Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.

Common duplication problems, and corresponding solutions are:

Complex Class

 Tip:   Before tackling complexity, make sure that you eliminate any duplication first. This often can reduce the size of classes significantly.

Complex classes like ClassMetadataFactory often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

While breaking up the class, it is a good idea to analyze how other classes use ClassMetadataFactory, and based on these observations, apply Extract Interface, too.

Bug introduced by
Accessing isMappedSuperclass on the interface Doctrine\Common\Persistence\Mapping\ClassMetadata suggest that you code against a concrete implementation. How about adding an instanceof check?

If you access a property on an interface, you most likely code against a concrete implementation of the interface.

Available Fixes

  1. Adding an additional type check:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeInterface $object) {
        if ($object instanceof SomeClass) {
            $a = $object->a;
        }
    }
    
  2. Changing the type hint:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeClass $object) {
        $a = $object->a;
    }

Bug Best Practice introduced by
The expression $parent->generatorOptions of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Duplication introduced by
This code seems to be duplicated across 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.

You can also find more detailed suggestions in the “Code” section of your repository.

This code seems to be duplicated across 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.

You can also find more detailed suggestions in the “Code” section of your repository.
