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');
}
}
