<snip last idea>
At Steve Alexander's suggestion, I'm going to try subclassing DataBlob
from PersistentMapping.
So now I need to add attribute support...
How do the following three methods sound:
def __getattr__(self,name):
try:
return PersistentMapping.__getattr__(self,name)
except AttributeError,e:
try:
return self.__getitem__(name)
except KeyError:
raise AttributeError, e
def __setattr__(self,name,value):
self.__setitem__(self,name,value)
def __delattr__(self,name):
try:
self.__delitem__(self,name)
except KeyError,e:
raise AttributeError,e
Can anyone see any problems?
cheers,
Chris
