rawData

private final StrategyType rawData

Specifications: spec_public non_null
is in groups: objectState
maps rawData.objectState \into objectState

iterator

public IndefiniteIterator iterator()

Description copied from interface: StrategyType

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).
