Can't find a method in Bitrix?

Question

1C-Bitrix

I can not understand where this method is located? Judging by Htbr, it is not Bitrix, but where could it be put? Can't find a description...

<?
use Htbr\Utils;


$arResult['CONTACTS'] = Utils::getElements(IBLOCK_CONTACTS, ELEMENT_CONTACTS)[0];
?>

Answer 1

Well, you can determine the path to the class file using Reflection
But in general, usually just an IDE is used for this)
