## §4.6 Overriding access restrictions

Callin bindings may also mention inaccessible methods (cf. decapsulation §3.4). Due to the reverse call direction this is relevant only for base calls within `callin` methods. Base calls have unrestricted access to protected base methods. Accessing a base method with private or default visibility is also allowed, but signaled by a compiler warning.

##### Comment:

A base call to an inaccessible base method is considered harmless, since this is the originally intended method execution.

#### (a) Private methods from super classes

(Cf. §3.4.(d)) If a callin binding shall bind to a private base method, that method must be defined in the exact base class to which the current role class is bound using `playedBy`.
If a private base feature must indeed be callin-bound, a role class must be defined that is played by the exact base class defining the private feature. Another role bound to a sub-base-class can then be defined as a sub class of the first role. It will inherit the callin binding and through this it can access the desired feature.
