Can one write sth like:
def _decorator(self, foo):
What you're wanting to do isn't possible. Take, for instance, whether or not the code below looks valid:
class Test(object): def _decorator(self, foo): foo() def bar(self): pass bar = self._decorator(bar)
It, of course, isn't valid since
self isn't defined at that point. The same goes for
Test as it won't be defined until the class itself is defined (which its in the process of). I'm showing you this code snippet because this is what your decorator snippet transforms into.
So, as you can see, accessing the instance in a decorator like that isn't really possible since decorators are applied during the definition of whatever function/method they are attached to and not during instantiation.
If you need class-level access, try this:
class Test(object): @classmethod def _decorator(cls, foo): foo() def bar(self): pass Test.bar = Test._decorator(Test.bar)
