Handler States

Once the handler is started, it processes packets from security definition and multicast feeds. To get understanding in which state the Handler currently is, it's necessary to implement OnixS::Xetra::MarketData::MDI::HandlerStateChangeListener class interface and associate an instance with the Handler using OnixS::Xetra::MarketData::MDI::Handler::registerStateChangeListener member.

Below table describes all possible states for the handler:

State	Description
OnixS::Xetra::MarketData::MDI::HandlerState::Stopped	The handler is stopped or was not executed yet.
OnixS::Xetra::MarketData::MDI::HandlerState::Stopping	The intermediate state when the handler is not Stopped but not Started.
OnixS::Xetra::MarketData::MDI::HandlerState::Started	The handler is started.
OnixS::Xetra::MarketData::MDI::HandlerState::Starting	The intermediate state when the handler is not Started but not Stopped.
