動的型付け言語

Ruby

  def name
    @name
  end

protected
  def name=(value)
    @name = value
  end
end

Python

class PropertyTest1(object):
    def __init__(self):
        self._x = None
    def get_x(self):
        return self._x
    def set_x(self, value):
        self._x = value
    x = property(get_x, set_x)
