public interface StrategyType

Strategies for providing test data. These simply consist of a method iterator(), which can be called to return a new IndefiniteIterator object.

 IndefiniteIterator iterator()
          Compute a fresh indefinite iterator, which can be used to provide test data of some reference type.

Method Detail


public IndefiniteIterator iterator()
Compute a fresh indefinite iterator, which can be used to provide test data of some reference type. The indefinite iterator 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).
