This section provides information about more advanced development techniques supported by the Handler.

Thread affinity

FeedEngine provides the ability to set an affinity mask for threads. For example, OnixS::B3::MarketData::UMDF::FeedEngineThreadPoolSettings::threadAffinity method can be used to run FeedEngine's threads on the particular processor(s).

Warnings Concept

Miscellaneous non-critical issues may occur while the Handler's instance is being executed. The Handler processes such matters on its own; therefore, no special handling is required in that case. However, sometimes it is reasonable to be notified about such events. For this purpose, the Handler represents OnixS::B3::MarketData::UMDF::WarningListener class and invokes its OnixS::B3::MarketData::UMDF::WarningListener::onWarning member each time a non-critical issue occurs.
