遍历Map的方法

Map<String, ClientLink> clients = ClientLinkManager.getOnlineUsers();Iterator<Entry<String, ClientLink>> iter = clients.entrySet().iterator();while (iter.hasNext()) {    Map.Entry<String, ClientLink> entry = (Map.Entry<String, ClientLink>) iter.next();    //String key = entry.getKey();    ClientLink client = entry.getValue();    client.sendMsgToClient(msg);}
