How to fix   Duplicated Code   

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:

1
<?php

3
declare(strict_types=1);
4
5
namespace League\Event;
6
7
use Psr\EventDispatcher\EventDispatcherInterface;
8

class BufferedEventDispatcher implements EventDispatcherInterface, ListenerAcceptor
10
{
11
    use EventGeneratorBehavior {
12
        recordEvent as protected;
13
        releaseEvents as protected;
14
    }
15
16
    /**

     * @var EventDispatcherInterface
18
     */
19
    private $dispatcher;
20
21
    public function __construct(EventDispatcherInterface $dispatcher)
22
    {
23
        $this->dispatcher = $dispatcher;
24
    }
25
26
    public function dispatch(object $event): void
27
    {
28
        $this->recordEvent($event);
29
    }
30
31
    public function dispatchBufferedEvents(): void
32
    {
33
        foreach ($this->releaseEvents() as $event) {
34
            $this->dispatcher->dispatch($event);
35
        }

This method 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.

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