Let's say that I have a class defined in moduleA.py
which I want to add a method to, using some sort of loader method that takes a the name of a second module and the method defined there that should be bound
class ClassA(object):
def __init__(self,config):
super(ClassA, self).__init__()
self.a = 1
self.b = 2
self.meth1 = self. bind_method(config)
def bind_method(self,config):
# load method
<return method defined in config as a str 'moduleB.meth2'>
def calling_method():
return self.meth1()
where the method defined in moduleB.py
looks something like:
def meth2(self):
return self.a + self.b
The point being that I want to be able to write meth2
to be able to access class variables of ClassA
once it is bound. This way, when you would have something like:
from moduleA import ClassA
A = ClassA()
aout = A.calling_method()
Calling A.calling_method()
properly calls the method defined in moduleB.py
.
I've seen this sort of binding done in answers on SO after ClassA
is instantiated using types.MethodType
, but I haven't been able to dig up how to bind inside the class definition so that it is done internally when the class is instantiated.
Any suggestions on what should go in the bind_method
method would be much appreciated.
