Attribute resolver factory

The hydrator uses AttributeResolverFactoryInterface implementation to create attribute resolvers. The package provides two implementations out of the box:

• ReflectionAttributeResolverFactory. Uses reflection to create attribute resolver, and can create attribute resolvers without dependencies only.
• ContainerAttributeResolverFactory. Uses PSR-11 compatible DI container to create attribute resolver.

Default factory used depends on the environment. When using hydrator package within the Yii ecosystem (an application uses Yii Config), default is ContainerAttributeResolverFactory. Otherwise, it is ReflectionAttributeResolverFactory.

Using attribute resolver factory

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

use Yiisoft\Hydrator\AttributeHandling\ResolverFactory\ContainerAttributeResolverFactory;

/**
 * @var Psr\Container\ContainerInterface $container
 */ 
$attributeResolverFactory = new ContainerAttributeResolverFactory($container);

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