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()). i����c���������C���s����t��t�|����j�|��|�|�|���}�t�d����|�j����D����}�xb�|�D]Z�}�xQ�t�|�d�t������D]:�}�t�|�|�d����}�t�|�d�t���r`�|�j�|���q`�q`�WqD�Wt �|���|�_ �t����|�_�t����|�_ �t����|�_�t�j�|�_�|�S(���Nc���������s���s-���|��]#�\�}�}�t��|�d��t���r�|�Vq�d�S(���R���N(���t���getattrt���False(���t���.0t���namet���value(����(����s���/usr/lib64/python2.7/abc.pys ���<genexpr>Y���s��� t���__abstractmethods__R���(���t���superR ���t���__new__t���sett���itemsR���t���NoneR���t���addt ���frozensetR���R����t ���_abc_registryt ���_abc_cachet���_abc_negative_cachet���_abc_invalidation_countert���_abc_negative_cache_version(���t���mclsR���t���basest ���namespacet���clst ���abstractst���baseR���(����(����s���/usr/lib64/python2.7/abc.pyR���V���s����! c���������C���s{���t��|�t�t�j�f���s'�t�d�����n��t�|�|����r:�d�St�|��|���rX�t�d�����n��|��j�j�|���t �j �d�7_ �d�S(���s&���Register a virtual subclass of an ABC.s���Can only register classesNs'���Refusing to create an inheritance cyclei���(���t ���isinstancet���typet���typest ���ClassTypet ���TypeErrort ���issubclasst���RuntimeErrorR���R���R ���R���(���R ���t���subclass(����(����s���/usr/lib64/python2.7/abc.pyt���registeri���s����c���������C���s����|�d�|��j��|��j�f�IJ|�d�t�j�IJxR�t�|��j�j������D];�}�|�j�d���rA�t�|��|���}�|�d�|�|�f�IJqA�qA�Wd�S(���s'���Debug helper to print the ABC registry.s���Class: %s.%ss���Inv.counter: %st���_abc_s���%s: %rN( ���R���R���R ���R���t���sortedt���__dict__t���keyst ���startswithR���(���R ���t���fileR���R���(����(����s���/usr/lib64/python2.7/abc.pyt���_dump_registryw���s����c���������C���s����t��|�d�d���}�|�d�k �r1�|�|��j�k�r1�t�St�|���}�|�t�k�rR�|�}�n��|�|�k�sj�|�d�k�r��|��j�t�j�k�r��|�|��j �k�r��t �S|��j�|���S|��j�|���p��|��j�|���S(���s'���Override for isinstance(instance, cls).t ���__class__N(���R���R���R���R���R$���t ���_InstanceTypeR���R ���R���R���R���t���__subclasscheck__(���R ���t���instanceR*���t���subtype(����(����s���/usr/lib64/python2.7/abc.pyt���__instancecheck__����s���� c���������C���sa��|�|��j��k�r�t�S|��j�t�j�k��r@�t����|��_�t�j�|��_�n�|�|��j�k�rS�t�S|��j�|���}�|�t �k �r��t �|�t���s��t���|�r��|��j��j �|���n�|��j�j �|���|�S|��t�|�d�d���k�r��|��j��j �|���t�Sx4�|��j�D])�}�t�|�|���r��|��j��j �|���t�Sq��Wx7�|��j����D])�}�t�|�|���r |��j��j �|���t�Sq W|��j�j �|���t�S(���s'���Override for issubclass(subclass, cls).t���__mro__(����(���R���R���R���R ���R���R����R���R���t���__subclasshook__t���NotImplementedR#���t���boolt���AssertionErrorR���R���R���R(���t���__subclasses__(���R ���R*���t���okt���rclst���scls(����(����s���/usr/lib64/python2.7/abc.pyR5�������s6����N( ���R���R���R ���R���R���R+���R���R2���R8���R5���(����(����(����s���/usr/lib64/python2.7/abc.pyR ���A���s��� (����(���R ���R%���t���_weakrefsetR����R���R$���R4���R���t���propertyR���R ���(����(����(����s���/usr/lib64/python2.7/abc.pyt���<module>���s���
