Warnings Concept

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