AbstractValue
Magento\CatalogInventory\Model\Config\Backend\AbstractValue
What it does
This abstract base class serves as a foundation for catalog inventory configuration backend models in Magento 2.
Developers extend this class when creating custom config backend models that need to trigger stock reindexing when inventory-related configuration values are saved in the admin panel.
It injects stock indexer dependencies to ensure inventory data stays synchronized when configuration changes occur.
