## 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.

  WARNING: This API is experimental and might change in incompatible ways in the next release.

                                              int limit)

      Constructor.
      Parameters:
        `a` - Automaton to create finite string from.
        `limit` - Maximum number of finite strings to create, or -1 for infinite.

    - #### next

          public IntsRef next()

      Description copied from class: `FiniteStringsIterator`
      Generate next finite string. The return value is just valid until the next call of this method!
      Overrides:
        `next` in class `FiniteStringsIterator`
      Returns:
        Finite string or null, if no more finite strings are available.

    - #### size

          public int size()

      Number of iterated finite strings.
