shortIterator

public ShortIterator shortIterator()

Description copied from interface: ShortStrategyType

Compute a fresh ShortIterator, which can be used to provide test data of type short. The ShortIterator 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).

Specifications inherited from overridden method in interface ShortStrategyType:

assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;
