Dynamic attributes

[Miki Tebeka]

Hello All,

Is there an "official" way to do the following?

class _setter:
    def __init__(self, dict, key):
        self.__dict = dict
        self.__key = key
    def __call__(self, value):
        self.__dict[self.__key] = value


class _getter:
    def __init__(self, dict, key):
        self.__dict = dict
        self.__key = key
    def __call__(self):
        return self.__dict[self.__key]

class DynAttribs:
    def __init__(self):
        self.__dict = {}
    def addAttrib(self, attrib, value = None):
        try: # check if we were initialized
            self.__dict
        except:
            DynAttribs.__init__(self)
        key = '__da%s' % attrib
        self.__dict[key] = value
        self.__dict__[attrib] = _getter(self.__dict, key)
        self.__dict__['set%s' % attrib] = _setter(self.__dict, key)



>>> class XY(common.DynAttribs):
...  def __init__(self, x, y):
...	self.addAttrib('x', x)
...  	self.addAttrib('y', y)
...
>>> xy = XY(1,2)
>>> xy.x()
1
>>> xy.setx(100)
>>> xy.x()
100

Of course, you can add variant checks when assigning, but this is the
general idea.

Bye.
