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 ` the interface, or the candidate itself declares that it `provides ` 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)allNr) implementedBy providedByappendrnamesAndDescriptions_verify_elementrlenr ) iface candidate tentativevtypetesterexcsnamedesces E/home/dcms/DCMS/lib/python3.12/site-packages/zope/interface/verify.py_verifyr#)sB |$$!!
