|virtual void||onOrderBookUpdated (const OrderBook &book, const MessageInfo &msgInfo)=0|
Defines the interface through which the Handler notifies subscribers that all the changes from current multicast message block are applied to the order book.
Is called when the order book is updated.
In compare to the change reported through OnixS::ICE::iMpact::MarketData::OrderBookChangeListener interface, update represents a complex operation and usually consists of multiple changes. Also, books reported via OnixS::ICE::iMpact::MarketData::OrderBookUpdateListener interface are always in a valid state, whereas atomic change may invalidate book until subsequent change.
|book||is a 'up-to-date' book associated with given market.|
|msgInfo||information about multicast message block.|
