Class IlcIntDeltaRequiredIterator

An instance of the class IlcIntDeltaRequiredIterator is an iterator that traverses the elements of the required delta set of an instance of IlcIntSetVar (a constrained set variable). The order in which the iterator traverses the required delta set is not predictable.

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 its required delta set.

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

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 required delta set.
