Hi
I have a closed class and 2 factories function
class Data:
def __init__(self):
self.payload=None
def data_from_string(payload):
data=Data()
data.payload=payload
return data
def data_from_file(f):
data=Data()
data.payload=f.read()
return data
And I want to extend the class, by first including the factories
function inside the constructor,
second add some method to the class.
class MyData(Data):
def __init__(self, arg):
# I know this coke is not working, this is to show you
# what I expect
if isinstance(arg, file):
self=data_from_file(arg)
else:
self=data_from_string(arg)
return self
def len(self):
return len(self.payload)
And how I want to use it
>>> m=MyData('hello')
>>> print m.len()
5
any idea ?
Alain
