BillingAddressManagement

Magento\Quote\Model\BillingAddressManagement

What it does

This class manages billing address operations for shopping cart quotes in Magento 2.

Developers use it to assign a billing address to a cart (optionally using it for shipping too) or retrieve the current billing address.

It handles validation, persistence, and thread-safe operations through mutex locking to prevent race conditions during checkout.
