class ProductVariationAccessControlHandler in Commerce Core 8.2

Provides an access control handler for product variations.

Product variations are always managed in the scope of their parent (the product), so they have a simplified permission set, and rely on parent access when possible:

• A product variation can be viewed if the parent product can be viewed.
• A product variation can be created, updated or deleted if the user has the "manage $bundle commerce_product_variation" permission.

The "administer commerce_product" permission is also respected.
