Nirvana C++ : Creating a Session

To interact with a Nirvana Server, the first thing to do is create a Nirvana Session (nSession) object, which is effectively your logical and physical connection to a Nirvana Realm.

Creating a Nirvana Session Object

  1. Create a nSessionAttributes object with the RNAME value of your choice 

    std::string[] RNAME=({"nsp://127.0.0.1:9000"});
int length = 1;
nSessionAttributes *nsa=new nSessionAttributes(RNAME,length)

  2. Call the create method on nSessionFactory to create your session 

    Session *mySession = nSessionFactory::create(nsa);

    Alternatively, if you require the use of a session reconnect handler to intercept the automatic reconnection attempts, pass an instance of that class too in the create method: 

    class myReconnectHandler :
    public nReconnectHandler
     {

     //implement tasks associated with reconnection

     }

 myReconnectHandler rhandler=new myReconnectHandler();
 nSession *mySession=nSessionFactory::create(nsa, rhandler);

Initializing a Nirvana Session

  1. Initialise the session object to open the connection to the Nirvana Realm 

    mySession->init();
