some code meaning

Sorry to ask that.
In the Display -> View -> product-> reversed
I note the following code, just before the hikashop_product_price_main DIV.
What's the meaning of it?
Thanks

<?php
  if(!empty($this->element->extraData->rightBegin))
    echo implode("\r\n",$this->element->extraData->rightBegin);
?>

Hi there,

That's a code we added so you can display more information or feature through a plugin.
For example it's used by HikaMarket to display the edit buttons on the front end.
If you want more information about it I'll be please to explain you how we do this.
