Class BaseOperationAbstract

Shared state and dispatch plumbing for every provider's operations.

This class owns exactly what every API style has in common — the instance authentication token, the resolved transport settings, and the shallow per-request merge — and delegates the actual HTTP call to the provider- agnostic sendRequest pipeline. Protocol-specific base classes subclass it: GraphQLOperation adds GraphQL envelope handling and RestOperation adds query-string and JSON-body handling without duplicating any of the plumbing here.
