Understanding Handler Events

Uncovers Handler processing machinery in terms of events raised by the Handler while processing market data.

To meet the needs, SDK exposes service for listeners whose members are invoked by the OnixS::Senaf::MarketData::Handler instance once registered.

The following table summarizes the Handler events.

Event	Description
OnixS::Senaf::MarketData::ErrorListener::onError	Invoked by the Handler when error occurred
OnixS::Senaf::MarketData::WarningListener::onWarning	Invoked by the Handler when warning occurred
OnixS::Senaf::MarketData::HandlerStateChangeListener::onHandlerStateChange	Invoked by the Handler when its state changed
OnixS::Senaf::MarketData::LogReplayListener::onReplayFinished	Invoked by the Handler when log replay finished
