byteIterator
public ByteIterator byteIterator()
- Description copied from interface:
ByteStrategyType
- Compute a fresh ByteIterator, which can be used to
provide test data of type byte. The
ByteIterator 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).
