Class IlcIntVarDeltaIterator

An instance of the class IlcIntVarDeltaIterator is an iterator that traverses the values belonging to the domain-delta of a constrained integer variable (that is, an instance of IlcIntVar).

For more information, see the concepts Propagation, Domain-Delta, and Iterator.

This constructor creates an iterator associated with var to traverse the values belonging to the domain-delta of var.

This member function returns IlcTrue if there is a current element and the iterator points to it. Otherwise, it returns IlcFalse.

To traverse the values belonging to the domain-delta of a constrained integer variable, use the following code:

 IlcInt val;
 for (IlcIntVarDeltaIterator iter(var); iter.ok(); ++iter){
         val = *iter;
         // do something with val
 }

This operator returns the current element, the one to which the invoking iterator points.

This operator advances the iterator to point to the next value in the domain-delta of the constrained integer variable.
