javascript - how to get socket.io number of clients in room? -

-

my socket.io version 1.3.5

i want number of clients in particular room.

this code.

 socket.on('create or join', function (numclients, room) {             socket.join(room);     });

i use code clients in room :

console.log('number of clients',io.sockets.clients(room));

to number of clients in room can following:

    function numclientsinroom(namespace, room) {       var clients = io.nsps[namespace].adapter.rooms[room];       return object.keys(clients).length;     }

this variable clients hold object each client key. number of clients (keys) in object.

if haven't defined namespace default 1 "/".

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
