This module provides a basic “weak method” implementation, WeakMethod. It uses weakref.WeakRef which, used on its own, produces weak methods that are dead on creation, not very useful. Use the getWeakRef(object) module function to create the proper type of weak reference (weakref.WeakRef or WeakMethod) for given object.

(obj, notifyDead=None)¶Get a weak reference to obj. If obj is a bound method, a WeakMethod object, that behaves like a WeakRef, is returned; if it is anything else a WeakRef is returned. If obj is an unbound method, a ValueError will be raised.
