No i don't use database,
Server side, i've got
- an static hashmap<idUser,usermodel> with all users online. ( add and
remove users by connectionEvents received from client)
- an static hashmap<idUser,Event> to know wich events to which
client .
for example :
- on the client,
=>jim connect --> that sends an eventConnection to server --
> add jim_user to the hashmap and return to client
- another client;
=>Abhiram connect --> that sends an eventConnection to server
--> add_Abhiram_user to the hashmap, add the events to other users
( hashmap<Jim_User,Event>)
so jim_user receive the event and jim_user knows that Abhiram is
connected
- jim want to says something to all other user --> jim users send a
messageEvent to the server ( for all keyset of the
hashmap<idUser,Event> )
.......
.....
- jim want to speak with Abhiram only) --> send a messageEvent to the
server and put only the event for the hashmap<Abhiram_user,Event> ...
sorry for my english ! I'm Frenchman.
