Class LimitedFiniteStringsIterator

java.lang.Object

org.apache.lucene.util.automaton.FiniteStringsIterator

org.apache.lucene.util.automaton.LimitedFiniteStringsIterator

public class LimitedFiniteStringsIterator
extends FiniteStringsIterator

FiniteStringsIterator which limits the number of iterated accepted strings. If more than limit strings are accepted, the first limit strings found are returned.

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.
