      • authKeysForEidsUnchanged

        public boolean authKeysForEidsUnchanged​(java.util.Map<EidLispAddressKey,​EidLispAddress> eids,
                                        long timeout)
        We maintain a HashMap with the update times of AuthenticationKey objects in the updatedEntries field. We keep entries in the HashMap for the Map-Register cache timeout interval, and lazy remove them afterwards. As a result the same EID will be considered updated during that interval, even on subsequent queries. This is necessary because more than one xTR may register the same EID, and to avoid complexity we don't store origin information. The performance trade-off is not significant, because during a typical cache timeout the same xTR will send only a few registration packets (2 for the default value of 90s, when UDP Map-Registers are sent at 1 minute intervals).
        Parameters:
        eids - List of EIDs to check
        timeout - MapRegister cache timeout value
        Returns:
        false if any of the EIDs in the eids list was updated in the last timout period, true otherwise
