intIterator
public IntIterator intIterator()
- Description copied from interface:
IntStrategyType
- Compute a fresh IntIterator, which can be used to
provide test data of type int. The
IntIterator returned should be freshly created.
Usually it should not be at its end. However, in rare cases it
might make sense to have an empty iterator be computed (e.g.,
by filtering).
