Same name and namespace in other branches

1. 10 core/modules/sdc/src/Plugin/Discovery/DirectoryWithMetadataDiscovery.php \Drupal\sdc\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

1 call to DirectoryWithMetadataDiscovery::findProvider()

Class

DirectoryWithMetadataDiscovery

Does the actual finding of the directories with metadata files.

Namespace

Drupal\Core\Plugin\Discovery

Code

private function findProvider(string $file, array $provider_paths) : string {
    $parts = explode(DIRECTORY_SEPARATOR, $file);
    array_pop($parts);
    if (empty($parts)) {
        return '';
    }
    $provider = $provider_paths[implode(DIRECTORY_SEPARATOR, $parts)] ?? '';
    return empty($provider) ? $this->findProvider(implode(DIRECTORY_SEPARATOR, $parts), $provider_paths) : $provider;
}
