[Christian Schulte]

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

Hello Christian,

Thank you!
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

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).

 

Best

Christian

Hello all,

In my script class, i have an array of CarDeparture pointer objects which
class contains several IntVar variables and some data information.

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
