Listening to Session Events

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

Note

Session event handling/listening is the synchronous operation, so it is recommended not to perform time-consuming tasks inside event handlers.

Example

using namespace OnixS::CME::iLink3;

class SessionStateListener : public SessionListener
{
public:

    void onStateChange(SessionStateId::Enum newState, SessionStateId::Enum prevState, Session* /*session*/) override
    {
        std::clog
            << "\nSession's state is changed, prevState="
            << SessionStateId::toString(prevState)
            << ", newState="
            << SessionStateId::toString(newState)
            << std::endl;
    }
};
