Return value

\RecursiveIteratorIterator A \RecursiveIteratorIterator object or array where the values are \SplFileInfo objects.

    $flags = \FilesystemIterator::KEY_AS_PATHNAME | \FilesystemIterator::CURRENT_AS_FILEINFO | \FilesystemIterator::SKIP_DOTS;
    $directory_iterator = new \RecursiveDirectoryIterator($directory, $flags);
    // Detect "my_component.component.yml".
    $regex = '/^([a-z0-9_-])+.component.yml$/i';
