Method Detail

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).

Specified by:
iterator in interface StrategyType

approve

public abstract boolean approve(Object elem)
Return true if the element is to be returned by the get() method.
