What it does
This class handles reading catalog rule entity data from the database by populating customer group IDs and website IDs into the rule entity.
Developers use this when loading catalog rules to ensure the rule's associated customer groups and websites are automatically loaded with the main entity data.
It's part of Magento's entity manager extension attribute loading mechanism.
