This package is a tool to make [dependency injection](https://en.wikipedia.org/wiki/Dependency_injection) and class instantiation easier. Its API allows class' dependencies to be discovered and injected automatically by the factory.

Retrievers help you inject dependencies, even if you can't or won't from the calling code, by retrieving them based on suggestions from the class authors:

```
use Psr\Log\LoggerInterface;

class Bar {

  /**
   * @suggestedDependency drupalContainerService:logger.channel.form $formLogger
   */
  public function __construct(LoggerInterface $formLogger, $severity) {
    // ...
  }

}
```

When used in a system in which Drupal's service container is available, the `logger.channel.form` service is a suggested dependency for the `$formLogger`parameter. The `drupalContainerService` retriever can retrieve this dependency and give it to the factory to be injected during class instantiation.

```
$factory = new SimpleFactory(new AnnotatedFinder(), new DrupalContainerServiceRetriever());
$bar = $factory->instantiate(Bar::class, [
  'severity' => LogLevel::WARNING,
]);
```

In this example, `Bar` is instantiated using an overridden dependency (value) for `$severity`, but `AnnotatedFinder`, and the hypothetical `DrupalContainerServiceRetriever` provide the factory with a dependency for `$formLogger` based on `Bar`'s `@suggestedDependency` annotation.
