## Class ByteRunAutomaton

- java.lang.Object
- - org.apache.lucene.util.automaton.RunAutomaton
  - - org.apache.lucene.util.automaton.ByteRunAutomaton

-     public class ByteRunAutomaton
      extends RunAutomaton

  Automaton representation for matching UTF-8 byte[].

- - ### Constructor Summary

    Constructors
    Constructor and Description
    `ByteRunAutomaton(Automaton a)` Converts incoming automaton to byte-based (UTF32ToUTF8) first
    `ByteRunAutomaton(Automaton a, boolean isBinary, int maxDeterminizedStates)` expert: if utf8 is true, the input is already byte-based

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
