Object Factory

The hydrator uses ObjectFactoryInterface implementation to create object when you use Hydrator::create() method: hydrator passes resolved constructor arguments to factory and obtains created object for next hydration. The package provides two implementations out of the box:

• ReflectionObjectFactory. Uses reflection to create object. It cannot create objects when some constructor arguments aren't resolved. This object factory is used by default.
• ContainerObjectFactory. Uses Yii Injector to create object that allow to use PSR-11 compatible DI container to resolve constructor argument not resolved by the hydrator.

Using object factory

To use non-default object factory, pass it to the hydrator constructor:

use Yiisoft\Injector\Injector;
use Yiisoft\Hydrator\ObjectFactory\ContainerObjectFactory;

/**
 * @var Psr\Container\ContainerInterface $container
 */ 
$injector = new Injector($container)
$objectFactory = new ContainerObjectFactory($injector);

$hydrator = new Hydrator(
    objectFactory: $objectFactory,
    // ...
);
