Order Books

The sample below demonstrates listening to Handler's events:

 
    struct MyOrderBookListener : public OrderBookListener
    {
        void onOrderBookChanged(const OrderBook& book, const Messaging::SbeMessage message) final 
        {
        }

        void onOrderBookUpdated(const OrderBook& book) final 
        {
        }

        void onOrderBookOutOfDate(const OrderBook& book) final 
        {
        }
 
    } orderBookListener;
 
    HandlerSettings settings;
    Handler handler(settings);
 
    handler.registerOrderBookListener(&orderBookListener);
