- - ### Constructor Detail

    - #### CharacterRunAutomaton

          public CharacterRunAutomaton(Automaton a)

      Construct with a default number of maxDeterminizedStates.

    - #### CharacterRunAutomaton

          public CharacterRunAutomaton(Automaton a,
                                       int maxDeterminizedStates)

      Construct specifying maxDeterminizedStates.
      Parameters:
        `a` - Automaton to match
        `maxDeterminizedStates` - maximum number of states that the automaton can have once determinized. If more states are required to determinize it then a TooComplexToDeterminizeException is thrown.

  - ### Method Detail

    - #### run

          public boolean run(String s)

      Returns true if the given string is accepted by this automaton.

    - #### run

          public boolean run(char[] s,
                             int offset,
                             int length)

      Returns true if the given string is accepted by this automaton
