Method Details

adapter_hook(self, interface, object, name='', default=None)

Hook function used when calling interfaces.

When called from Interface.__adapt__, only the interface and object parameters will be passed.

If the factory produces `None`, then the default is returned. This allows us to prevent adaptation (if desired) and make the factory decide whether an adapter will be available.
