That's fine. But have make sure to update the variables! Christian

Ok, then i will use a LocalHandle. Do you confirm that it is not a bad idea to pass such an object as a parameter of a brancher (knowing that it contains several IntVar variables) ? Cheers, Christine 2013/4/23 Christian Schulte <cschu...@kth.se> 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
