This involves: - Making sure the candidate claims that it provides the interface using ``iface.providedBy`` (unless *tentative* is `True`, in which case this step is skipped). This means that the candidate's class declares that it `implements <zope.interface.implementer>` the interface, or the candidate itself declares that it `provides <zope.interface.provider>` the interface - Making sure the candidate defines all the necessary methods - Making sure the methods have the correct signature (to the extent possible) - Making sure the candidate defines all the necessary attributes :return bool: Returns a true value if everything that could be checked passed. :raises zope.interface.Invalid: If any of the previous conditions does not hold. .. versionchanged:: 5.0 If multiple methods or attributes are invalid, all such errors are collected and reported. Previously, only the first error was reported. As a special case, if only one such error is present, it is raised alone, like before. �cT)�allN� r ) � implementedBy� providedBy�appendr �namesAndDescriptions�_verify_elementr �lenr ) �iface� candidate� tentative�vtype�tester�excs�name�desc�es �7/usr/lib/python3/dist-packages/zope/interface/verify.py�_verifyr# ' s� � �@ ��|��$�$���!�!�� �D� �V�I� .� � � �$�U�I�6�7��0�0�T�0�:� � ��d� � �E�4��y�%� @�� � �t�9��>��q�'�M� �e�Y��5�5� �� � � �K�K��N�N�� �s � B� B7� B2�2B7c �� � t ||� }t |t � sy t j |� st j |� ry t |t � r4t |t � r|dk( rt || |d�� }nyt || |�� }njt |t � r)t |j � t u rt || |� }n1t |t � r|dk( ry t |� st! |d|| |� �y t# |j% � |j% � � }|rt! |||| |� �y # t $ r% t |t � s|dk( rY y t | ||� �w xY w)Nr r )r �imlevel)r z implementation is not a method)�getattr�AttributeError� isinstancer r �inspect�ismethoddescriptor� isbuiltinr �typer � MethodTypes�__func__r �property�callabler � _incompat�getSignatureInfo)r r r r r �attr�meth�messs r" r r ] sV � �;��y�$�'�� �d�F� #���!�!�$�'�7�+<�+<�T�+B� ��$� �%� �i�� &�5�C�<� ��e�$��B�D� ��e�$�7�D� �T�;� '��4�=�=�!�\�1��$��t�,�� �D�(� #��� � � ��~�,�T�3S�-1�5�)�E� E� � �T�*�*�,�d�.C�.C�.E� F�D� �(��t�T�5�)�L�L� ��s � ;��4��(�e�s�l� �"�5�$� �:�:� ;�s � D2 �2 E �E c � � t | ||d�� S )zF Verify that the *candidate* might correctly provide *iface*. r �r �r# �r r r s r" r r � s � � �5�)�Y�c� :�:� c � � t | ||d�� S )N�or7 r8 r9 s r" r r � s � � �5�)�Y�c� :�:r: z*implementation requires too many argumentsc � � t |d � t | d � kD rt S t |d � t | d � k r|d sy| d r|d sy| d r|d syy y )N�required� positional�varargsz-implementation doesn't allow enough arguments�kwargsz0implementation doesn't support keyword argumentsz1implementation doesn't support variable arguments)r � _MSG_TOO_MANY)r> � implementeds r" r1 r1 � sy � � �;�z� "�#�c�(�:�*>�&?�?� � � �[� � &� '�#�h�|�.D�*E� E��I�&�>����+�h�"7�A�� ��;�y�#9�B� $:�r: )FN)F)�__doc__r) �sys�typesr r �zope.interface.exceptionsr r r r r �zope.interface.interfacer r r �__all__r- r# r r r rB r1 � r: r" �<module>rK ss �� � � � � � :� @� 6� -� 5� E� E� �� �� �n� �4�l>M�D;� ;� ��� � �<� � Cr:
