ReadHandler
Magento\Catalog\Model\Category\Link\ReadHandler
What it does
This class is responsible for reading and loading category link data for products in Magento 2.
It retrieves all category associations for a product entity and populates them as extension attributes, making category link information available when working with product objects.
Developers typically don't interact with this class directly - it's automatically invoked by Magento's entity manager when loading product data.
