    attr_accessor :value


    # Creates a new Cell object and, if *source_text* is provided, populates
    # the object.
    #
    # @example
    #   Cell.new
    #   Cell.new('some value')
    #
    # @param source_text [String] The Gherkin text that will be used to populate the model
    # @raise [ArgumentError] If *source_text* is not a String
    # @return [Cell] A new Cell instance
    def initialize(source_text = nil)

    end

    # Returns a string representation of this model. For a Cell model,
    # this will be Gherkin text that is equivalent to the cell being modeled.
    #
    # @example
    #   cell.to_s
    #
    # @return [String] A string representation of this model
    def to_s
      # Vertical bars and backslashes are special characters that need to be escaped
      @value ? @value.gsub('\\', '\\\\\\').gsub('|', '\|') : ''
    end

    # See `Object#inspect`. Returns some basic information about the
    # object, including its class, object ID, and its most meaningful
    # attribute. For a Cell model, this will be the value of the
    # cell. If *verbose* is true, provides default Ruby inspection
    # behavior instead.
    #
    # @example
    #   cell.inspect
    #   cell.inspect(verbose: true)
    #
    # @param verbose [Boolean] Whether or not to return the full details of
    #   the object. Defaults to false.
    # @return [String] A string representation of this model
    def inspect(verbose: false)
      return super(verbose: verbose) if verbose
