Class IntVarIterator

java.lang.Object
com.google.ortools.constraintsolver.BaseObject
com.google.ortools.constraintsolver.IntVarIterator
public class IntVarIterator extends BaseObject
The class Iterator has two direct subclasses. HoleIterators
iterates over all holes, that is value removed between the
current min and max of the variable since the last time the
variable was processed in the queue. DomainIterators iterates
over all elements of the variable domain. Both iterators are not
robust to domain changes. Hole iterators can also report values outside
the current min and max of the variable.
HoleIterators should only be called from a demon attached to the
variable that has created this iterator.
IntVar* current_var;
std::unique_ptr<IntVarIterator> it(current_var->MakeHoleIterator(false));
for (const int64_t hole : InitAndGetValues(it)) {
use the hole
}
