boost::openmethod::method<Id, ReturnType(Parameters...), Registry>::override

Add overriders to method

Synopsis

template<auto Fn...>
class override;

override, instantiated as a static object, adds one or more overriders to an open‐method.

Fn must be a function that fulfills the following requirements:

Have the same number of formal parameters as the method.
Each `virtual_ptr<T>` in the method's parameter list must have a corresponding `virtual_ptr<U>` parameter in the same position in the overrider's parameter list, such that `U` is the same as `T`, or has `T` as an accessible unambiguous base.
Each `virtual_<T>` in the method's parameter list must have a corresponding `U` parameter in the same position in the overrider's parameter list, such that `U` is the same as `T`, or has `T` as an accessible unambiguous base.
All other formal parameters must have the same type as the method's corresponding parameters.
The return type of the overrider must be the same as the method's return type or, if it is a polymorphic type, covariant with the method's return type.
