README

Lets you easily create decorator classes to dynamically modify the behaviors of Doctrine Collection objects, including the collection objects used by Doctrine ORM in your entities.

Motivation

Custom collection classes won't come to Doctrine ORM anytime soon. Therefore, the only way to modify the behavior of a Doctrine collection is to use decorators. However, creating a Collection decorator by hand is a tedious process.

Synopsis

The decorator class extending one of our abstract classes:

use Doctrine\Common\Collections\Collection;
use Rekalogika\Collections\Decorator\AbstractCollectionDecorator;

/**
 * @extends AbstractCollectionDecorator<array-key,Book>
 */
class BookCollection extends AbstractCollectionDecorator
{
    /**
     * @param Collection<array-key,Book> $collection
     */
    public function __construct(private Collection $collection)
    {
    }

    protected function getWrapped(): Collection
    {
        return $this->collection;
    }

    // add and override methods here:
    // ...
}

The usage in an entity:

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity()]
class BookShelf
{
    /**
     * @var Collection<array-key,Book>
     */
    #[ORM\OneToMany(targetEntity: Book::class)]
    private Collection $books;

    public function __construct()
    {
        $this->books = new ArrayCollection();
    }

    public function getBooks(): BookCollection
    {
        return new BookCollection($this->bookskkk);
    }
}
