-Lazy Collections
-================
-
-To create a lazy collection you can extend the
-``Doctrine\Common\Collections\AbstractLazyCollection`` class
-and define the ``doInitialize`` method. Here is an example where
-we lazily query the database for a collection of user records:
-
-.. code-block:: php
- use Doctrine\DBAL\Connection;
-
- class UsersLazyCollection extends AbstractLazyCollection
- {
- /** @var Connection */
- private $connection;
-
- public function __construct(Connection $connection)
- {
- $this->connection = $connection;
- }
-
- protected function doInitialize() : void
- {
- $this->collection = $this->connection->fetchAll('SELECT * FROM users');
- }
- }
