booleanIterator

public BooleanIterator booleanIterator()

Description copied from interface: BooleanStrategyType

Compute a fresh BooleanIterator, which can be used to provide test data of type boolean. The BooleanIterator 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 BooleanStrategyType:

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