Extracts the queried order types and statuses, or NULL when they don't form a rewritable set: the 'type' and 'status' args must both be set and contain only non-empty strings, cover at least two statuses (a single status is already served by the type_status_date index), and stay within the branch cap.

Method of the class: OrdersTableStatusUnionQuery{}

No Hooks.

Returns

Array[]|null. Array of [ types, statuses ] (each a list of unique strings), or NULL when ineligible.

Usage
