A @Saga's handler function of processor: it returns the requests of the commands it derives (requestsOf); the saga's @OnRejected handlers, the rejections, take the rejections of those commands, and its @OnCommitted handlers, the commits, their success receipts. It derives only the commands of the classes derives lists, schedules only those schedules lists and calls only those calls lists (@Sends).
