      • handleMessage

        public void handleMessage​(SimPause sp)

      • handleMessage

        public void handleMessage​(SimStart ss)
        Receives the SimStart message, used to start the clock. The server's clock offset is subtracted from the start time indicated by the server.

        CashPosition is the last message sent by Accounting. This is normally when any broker would submit its bids, so that's when this VizBroker will do it.

      • handleMessage

        public void handleMessage​(TariffSpecification spec)
        Handles a TariffSpecification. These are sent by the server when new tariffs are published. If it's not ours, then it's a competitor's tariff. We keep track of competing tariffs locally, and we also store them in the tariffRepo.

      • handleMessage

        public void handleMessage​(TariffTransaction ttx)
        Handles a TariffTransaction. We only care about certain types: PRODUCE, CONSUME, SIGNUP, and WITHDRAW.
