Usage

Basic usage

Use phpDoc @template as definition of template types:

/**
 * @template IEntity
 */
class Repository {

	public function save(IEntity $entity)
	{
		...
	}

}

Now you can generate own class generated from template. Symbol _ is default separator between class name and template type.

class Article {}

$articleRepository = new Repository_Article;
$articleRepository->save(new Article); // works
$articleRepository->save(11); // fail

If you need to use multiple template types, define them in phpDoc:

/**
 * @template IEntity, IEntityManager
 */
...

and work with it similarly:

$articleRepository = new Repository_Article_EntityManager;
...

If you want to remove typehint:

$repository = new Repository_;
$repository->save('yeah'); // works
$repository->save(33); // works
$repository->save(new stdClass()); // works
...

Working with namespaces

Use absolute class names:

$article = new App\Article;
$article->text = 'Foo';

$articleRepository = new App\Repository_App\Article;
$articleRepository->save($article);

Or you can use use statements:

use App\Article;
use App\Repository_App\Article as ArticleRepository;

$article = new Article;
$article->text = 'Foo';

$articleRepository = new ArticleRepository;
$articleRepository->save($article);

Autowiring

services:
	- ArticleRepository_Article
	- ArticleService

use ArticleRepository_Article as ArticleRepository;

class ArticleService {

	private $repository;

	public function __construct(ArticleRepository $repository)
	{
		$this->repository = $repository;
	}

}

Inheritance rules

abstract class Entity {}
class Page extends Entity {}
class Article extends Page {}
abstract class Repository {}

/** @template Page */
class PageRepository extends Repository {
	public function(Page $entity) {}
}

$pageRepository = new PageRepository;
$articleRepository = new PageRepository_Article;

echo $pageRepository instanceof Repository; // TRUE
echo $pageRepository instanceof PageRepository; // TRUE

echo $articleRepository instanceof Repository; // TRUE
echo $articleRepository instanceof PageRepository; // FALSE
