Dear All,
I would like to make a new class inheriting from a class based on
UniqueRepresentation. My goal, among other things, is to preparse the
arguments a little before calling the class I am inheriting from.
Unfortunately this class also does some preparsing via __classcall__ to make
the input hashable. Could you point me to the correct way of setting this up?
Sketch of the situation:
class OldFoo(UniqueRepresentation):
@staticmethod
def __classcall__(self, data):
# make data hashable
return super(oldFoo, self).__classcall__(self, hashable_data)
def __init__(self, hashable_data):
# do something
class NewFoo(OldFoo):
# First neutralize OldFoo __classcall__
__classcall__ = None
def __init__(self, data):
# preparse data then initialize OldFoo
If __classcall__ were not there I would call OldFoo.__init__ but this does
not seem to work with OldFoo.__classcall__
Thanks
S.
