If *maxsize* is set to None, the LRU features are disabled and the cache can grow without bound. If *typed* is True, arguments of different types will be cached separately. For example, f(3.0) and f(3) will be treated as distinct calls with distinct results. Arguments to the cached function must be hashable. View the cache statistics named tuple (hits, misses, maxsize, currsize) with f.cache_info(). Clear the cache and statistics with f.cache_clear(). Access the underlying function with f.__wrapped__.

If no *abcs* are given, the algorithm works exactly like the built-in C3 linearization used for method resolution. If given, *abcs* is a list of abstract base classes that should be inserted into the resulting MRO. Unrelated ABCs are ignored and don't end up in the result. The algorithm inserts ABCs where their functionality is introduced, i.e. issubclass(cls, abc) returns True for the class itself but returns False for all its direct base classes. Implicit ABCs for a given class (either registered or inferred from the presence of a special method like __len__) are inserted directly after the last ABC explicitly listed in the MRO of said class. If two implicit ABCs end up next to each other in the resulting MRO, their ordering depends on the order of types in *abcs*. �__abstractmethods__r Nc 3 s | ]}t |� �V qd S )N)� issubclass)r@ �b)�baser r rc � s z_c3_mro.<locals>.<genexpr>c s g | ]}t |� d ��qS ))�abcs)�_c3_mro)r@ r� )r� r r rC � s z_c3_mro.<locals>.<listcomp>c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s ) � enumerate�reversed� __bases__r[ rX �listr� �anyr� �remover� ) rB r� �i�boundary�explicit_bases�abstract_bases� other_bases�explicit_c3_mros�abstract_c3_mros� other_c3_mrosr )r� r� r r� ~ s( r� c s� t �j�� � �fdd���fdd��D ���fdd���fdd��D ��t ���g }x��D ]�}g }x<|j� D ]0}|� krlt�|�rl|j�fdd�|jD �� qlW |s�|j|� qZ|jtd d � x,|D ]$}x |D ]}||kr�|j|� q�W q�W qZW t�|d �S ) z�Calculates the method resolution order for a given class *cls*.
