      Throws:
      IllegalArgumentException - if the string cannot be parsed to boolean.

    • isBoolean

      public static boolean isBoolean(char[] text, int offset, int length)
      returns true iff the sequence of chars is one of "true","false".
      Parameters:
      text - sequence to check
      offset - offset to start
      length - length to check
