1. 10 core/modules/sdc/src/Plugin/Discovery/DirectoryWithMetadataDiscovery.php \Drupal\sdc\Plugin\Discovery\DirectoryWithMetadataDiscovery::findProvider()
2. 10 core/lib/Drupal/Core/Plugin/Discovery/DirectoryWithMetadataDiscovery.php \Drupal\Core\Plugin\Discovery\DirectoryWithMetadataDiscovery::findProvider()

Finds the provider of the discovered file.

The approach here is suboptimal because the provider is actually set in the plugin definition after the getIdentifier is called. So we either do this, or we forego the base class.

Parameters

string $file: The discovered file.

array $provider_paths: The associative array of the path to the provider.

Return value

string The provider

        return '';
    }
    $provider = $provider_paths[implode(DIRECTORY_SEPARATOR, $parts)] ?? '';
    return empty($provider) ? $this->findProvider(implode(DIRECTORY_SEPARATOR, $parts), $provider_paths) : $provider;
}
