How to use the autodocsumm.__init__.AutoSummClassDocumenter function in autodocsumm

doc_class = get_documenters(self.env.app)[objtype]
            args = (self.state, ) if sphinx_version >= [2, 1] else ()
            params = DocumenterBridge(
                env, reporter,

                                           self.options),
                lineno, *args)
        documenter = doc_class(params, self.arguments[0])
        if hasattr(documenter, 'get_grouped_documenters'):
            self._autosummary_documenter = documenter
            return documenter
        # in case the has been changed in the registry, we decide manually
        if objtype == 'module':

        elif objtype == 'class':
            documenter = AutoSummClassDocumenter(params, self.arguments[0])
        else:
            raise ValueError(
                "Could not find a valid documenter for the object type %s" % (
                    objtype))
