Should I be using abstract methods in this Python scenario?
- by sfjedi
I'm not sure my approach is good design and I'm hoping I can get a tip. I'm thinking somewhere along the lines of an abstract method, but in this case I want the method to be optional. This is how I'm doing it now...
from pymel.core import *
class A(object):
def __init__(self, *args, **kwargs):
if callable(self.createDrivers):
self._drivers = self.createDrivers(*args, **kwargs)
select(self._drivers)
class B(A):
def createDrivers(self, *args, **kwargs):
c1 = circle(sweep=270)[0]
c2 = circle(sweep=180)[0]
return c1, c2
b = B()
In the above example, I'm just creating 2 circle arcs in PyMEL for Maya, but I fully intend on creating more subclasses that may or may not have a createDrivers method at all! So I want it to be optional and I'm wondering if my approach is—well, if my approach could be improved?
