Client to client messaging

Hello,

I am new to TNL. I was interested in finding out whether there is an in-built mechanism in the EventConnection or NetInterface classes through which a client can identify specific clients and send them messages. Or should I make some private member (like ID or name) in the class which is a subclass of EventConnection (or the other ones I use: NetInterface, NetEvent).

Of course the server must let a client know the names/IDs of all existing other clients, this is something I have yet to do.

Currently, I just iterate through a loop (using the conn->getInterface()->getConnectionList() attained from the connection object - "conn" - I have on the server, which is of type "SimpleEventConnection", derived from EventConnection). I send all messages received on the server one by one to all existing clients. But I'd like to have the client being able to send messages to specific clients (just as a chat client does).

So what would I have to do at the time of instantiation of a client-connection (on the client or server side) and then at the time of sending the message from the client.

Thanks in advance.

I am using NetEvent to post the message. Here is the process function:


//----------------------------------------------------------------------------------//
void SimpleMessageEvent::process(EventConnection *conn)
{
printf("SimpleMessageEvent received:%s", msg);

TNL::Vector con_list = conn->getInterface()->getConnectionList();

printf("Server has %d clients!", con_list.size());

for(int i = 0; i < con_list.size(); i++){

SimpleEventConnection *con = (SimpleEventConnection *)con_list[i];
con->rpcMessageServerToClient(msg);
}
}
