How to free up the memory correctly?

[rafaelcapucho]

I know that there is the .Clear() method to call, but how should I do when I have nested structures like this:

CJAVal json_positions_list;

for(...){
      CJAVal json_position;

      json_position["account_number"] = account_number;
      json_position["takeprofit"] = takeprofit;
      json_position["digits"] = digits;
      
      json_positions_list.Add(json_position);
}

Calling json_positions_list.Clear() will also free the memory of the internals json_position elements?

Should I iterate of json_positions_list and free the memory one by one?

I want to get rid of json_positions_list memory entirely, would a delete json_positions_list works? I read that the delete command only works when the object is created using the new statement,

@vivazzi Any help is appreciated, Thanks!
