Display number of downloads

How can I get the number of downloads for each file within "product / show_block_product_files".

I would like to add it next to each file from within the "foreach ($this->element->files as $file) {" loop

I notice that the number of downloads is stored within #__hikashop_download table and does not seem to be available via the class properties. Are there any methods available to give me the number of downloads

TIA

NM. I've done it the old fashioned way.

$query = "SELECT `download_number` FROM `#__hikashop_download` WHERE `file_id` = '" . $file->file_id . "'";    
$db->setQuery($query);
$downloads = $db->loadResult();
