Member Function Documentation

virtual void onOrderBookUpdated ( const OrderBook &  book, const MessageInfo &  msgInfo  )

pure virtual

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.

Parameters

book	is a 'up-to-date' book associated with given market.
msgInfo	information about multicast message block.
