Use this metaclass to create an ABC. An ABC can be subclassed directly, and then acts as a mix-in class. You can also register unrelated concrete classes (even built-in classes) and unrelated ABCs as 'virtual subclasses' -- these and their descendants will be considered subclasses of the registering ABC by the built-in issubclass() function, but the registering ABC won't show up in their MRO (Method Resolution Order) nor will method implementations defined by the registering ABC be callable (not even via super()). c s&tj||||fi|}t||SN)r __new__r)mclsnamebases namespacekwargsclsrrrr)iszABCMeta.__new__cC t||S)z{Register a virtual subclass of an ABC.

If a class has had one of its abstract methods implemented after the class was created, the method will not be considered implemented until this function is called. Alternatively, if a new abstract method has been added to the class, it will only be considered an abstract method of the class after this function is called. This function should be called before any use is made of the class, usually in class decorators that add methods to the subject class. Returns cls, to allow usage as a class decorator.
