I'm trying to figure out if there's an elegant and concise way to have a class accessing one of its own properties when "used" as a dictionary, basically redirecting all the methods that'd be implemented in an ordered dictionary to one of its properties.
Currently I'm inheriting from IterableUserDict and explicitly setting its data to another property, and it seems to be working, but I know that UserDict is considered sort of old, and I'm concerned I might be overlooking something.
What I have:
class ConnectionInterface(IterableUserDict):
def __init__(self, hostObject):
self._hostObject= hostObject
self.ports= odict.OrderedDict()
self.inputPorts= odict.OrderedDict()
self.outputPorts= odict.OrderedDict()
self.data= self.ports
This way I expect the object to behave and respond (and be used) the way I mean it to, except I want to get a freebie ordered dictionary behaviour on its property "ports" when it's iterated, items are gotten by key, something is looked up ala if this in myObject, and so on.
Any advice welcome, the above seems to be working fine, but I have an odd itch that I might be missing something.
Thanks in advance.
