Is there a way to bind a decorator to all functions within a class generically, rather than explicitly stating it for every function?
I suppose it then becomes a kind of aspect, rather than a decorator and it does feel a bit odd, but was thinking for something like timing or auth it'd be pretty neat.
The cleanest way to do this, or to do other modifications to a class definition, is to define a metaclass.
Alternatively, just apply your decorator at the end of the class definition using inspect:
import inspect
class Something:
def foo(self):
pass
for name, fn in inspect.getmembers(Something, inspect.isfunction):
setattr(Something, name, decorator(fn))
In practice of course you'll want to apply your decorator more selectively. As soon as you want to decorate all but one method you'll discover that it is easier and more flexible just to use the decorator syntax in the traditional way.
