doubleIterator
public DoubleIterator doubleIterator()
- Description copied from interface:
DoubleStrategyType
- Compute a fresh DoubleIterator, which can be used to
provide test data of type double. The
DoubleIterator 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).
