OnixS C++ CME iLink 3 Binary Order Entry Handler  1.8.0
API Documentation
Listening to Session Events

OnixS C++ CME iLink 3 Handler exposes the OnixS::CME::iLink3::SessionListener class, whose virtual members are called by an instance of the OnixS::CME::iLink3::Session class, as response to a particular event occurred during the session life-time.

To be notified about a particular session event, overwrite appropriate member of the OnixS::CME::iLink3::SessionListener class, and supply a descendant instance to the OnixS::CME::iLink3::Session's constructor.

The OnixS::CME::iLink3::SessionListener interface class shows all events, exposed by the OnixS::CME::iLink3::Session class.

Session event handling/listening is synchronous operation. For this reason, it is recommended not to perform time-consuming tasks inside event handlers. For the same reason, it is not recommended to call from the event handler any Session method that could change Session state.
