public class DataConnectionManager implements JSONSerialization{

private static DataConnectionManager msManager = null;

public DataConnectionManager() {

//Initialize connection

}

public static DataConnectionManager getInstance() {

if(msManager == null) {

msManager = new DataConnectionManager();

}

return msManager;

}

public static void deserialize(JSONObject obj) {

msManager = new DataConnectionManager();

msManager.setFromJSON(obj);

}

}
