[gecode-users] pointer safe (sorry for multiple posting)

[Christian Schulte]

Just pass arrays by reference and not by value!

Hello all,

 

I would like to know if this functions are "pointer safe",

I was looking at the array implementation and I think

it manage its own memory allocation.

 

IntVarArray create(Space * h, int size)

{

   return IntVarArray(h,size,1,1000);

}

 

IntVar * get_IntVar(Space * h,IntVar * pos, IntVarArray array)

{

     IntVar * answer = new IntVar(h,1,1000);

     element(h, array, *pos, *answer); 

     return answer;

}

 

IntVar * get_IntVar(Space * h,int pos, IntVarArray array)

{

     return &array[pos];

}

 

I tried using new with IntVarArray but it not allowed.

Is there a problem of creating an IntVarArray in a function and returning
it?

is there a problem with the other two?

 

Thanks
