longIterator

public LongIterator longIterator()

Description copied from interface: LongStrategyType

Compute a fresh LongIterator, which can be used to provide test data of type long. The LongIterator 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 LongStrategyType:

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