- Direct Known Subclasses:
LimitedFiniteStringsIterator
Iterates all accepted strings.
If the Automaton
has cycles then this iterator may throw an
IllegalArgumentException
, but this is not guaranteed!
Be aware that the iteration order is implementation dependent and may change across releases.
If the automaton is not determinized then it's possible this iterator will return duplicates.
- WARNING: This API is experimental and might change in incompatible ways in the next release.
