def __get__(self, instance, owner):
Instead of directly returning the value directory, we look up each instance's value using
the instance itself as the key.
if instance is not None: # attribute lookup initiated from instance
if len(self._instance_values) < NonNullStringDescriptor.CAPACITY:
self._instance_values[instance] = self.__default
return self._instance_values.get(instance, self.__default)
else: # attribute lookup initiated via class
return self.__default
