Hi Christine,
If the data structure is small then you do not have to share it by use of a LocalHandle. If it is maybe not so small then the use of LocalHandle might be useful. I personally always use LocalHandle when I can use it (that is, I have a data structure shared between several entities in a space).

Inside the script copy constructor, i create a copy of the array of CarDeparture objects using a CarDeparture copy constructor which updates each of its IntVar variables and data. I am thinking to set a CarDeparture object as a parameter for a brancher. So, i should again do a copy of this object inside the brancher copy constructor. According to you, is it judicious to proceed like this concerning performance ? Or maybe, can i make the CarDeparture class inherit of LocalHandle (in order to be space dependant ?). Thank you all. Cheers, Christine
