Detailed Description

All Handler classes are located under the OnixS::ICE::iMpact::MarketData namespace. Header files are assembled in the "OnixS/ICE/iMpact/MarketData.h" header file.

Attention

The Handler needs credentials from ICE to login and download product definitions. Please contact ICE Support to get a username and password for TCP connection. When you receive it please update the connectivity configuration file with these values.

The typical way of using the Handler is as follows:

• Optionally create an instance of OnixS::ICE::iMpact::MarketData::HandlerSettings class to adjust Handler's options like activating logging;
• Create an instance of OnixS::ICE::iMpact::MarketData::Handler class;
• Register listener for errors to be notified about failures occurred while processing market data from multicast channels;
• Register listeners for miscellaneous events like product definition reception and/or changes in the market state;
• Create an subscription for interested markets by forming OnixS::ICE::iMpact::MarketData::MarketSubscriptions collection;
• Start a subscription by invoking OnixS::ICE::iMpact::MarketData::Handler::start member and supplying a previously created collection of subscriptions as a parameter;
• Process changes in books and states of the markets through previously registered listeners;
• Stop subscription using the OnixS::ICE::iMpact::MarketData::Handler::stop member.
