How to fix   Complexity   

Complex Class

Complex classes like StripeResource 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 StripeResource, and based on these observations, apply Extract Interface, too.

Bug introduced by
The method setRequestParams does only exist in Arcanedev\Stripe\Collection, but not in Arcanedev\Stripe\StripeO...v\Stripe\StripeResource.

It seems like the method you are trying to call exists only in some of the possible types.

Let’s take a look at an example:

class A
{
    public function foo() { }
}

class B extends A
{
    public function bar() { }
}

/**
 * @param A|B $x
 */
function someFunction($x)
{
    $x->foo(); // This call is fine as the method exists in A and B.
    $x->bar(); // This method only exists in B and might cause an error.
}

Available Fixes

  1. Add an additional type-check:

    /**
     * @param A|B $x
     */
    function someFunction($x)
    {
        $x->foo();
    
        if ($x instanceof B) {
            $x->bar();
        }
    }
    
  2. Only allow a single type to be passed if the variable comes from a parameter:

    function someFunction(B $x) { /** ... */ }

Bug introduced by
It seems like $response->getJson() targeting Arcanedev\Stripe\Http\Response::getJson() can also be of type null; however, Arcanedev\Stripe\Utiliti...convertToStripeObject() does only seem to accept array, maybe add an additional type check?

This check looks at variables that are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.

Bug introduced by
Since checkParameters() is declared private, calling it with static will lead to errors in possible sub-classes. You can either use self, or increase the visibility of checkParameters() to at least protected.

Let’s assume you have a class which uses late-static binding:

class YourClass
{
    private static function getTemperature() {
        return "3422 °C";
}

public static function getSomeVariable()
{
    return static::getTemperature();
}

}

The code above will run fine in your PHP runtime. However, if you now create a sub-class and call the getSomeVariable() on that sub-class, you will receive a runtime error:

class YourSubClass extends YourClass {
      private static function getTemperature() {
        return "-182 °C";
    }
}

print YourSubClass::getSomeVariable(); // Will cause an access error.

In the case above, it makes sense to update SomeClass to use self instead:

class YourClass
{
    private static function getTemperature() {
        return "3422 °C";
    }

    public static function getSomeVariable()
    {
        return self::getTemperature();
    }
}
