Listening to Session Events

To be notified about a session event, override the corresponding member of the OnixS::B3::BOE::SessionListener class, and supply the class instance to the OnixS::B3::BOE::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::B3::BOE;
 
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;
    }
};
