 def register_converter(self, converter, conv_type, conv_format=None, *, name=None):
 """ Register custom path parameter converter. :param BaseConverter converter: Converter Subclass of werkzeug's BaseConverter :param str conv_type: Parameter type :param str conv_format: Parameter format (optional) :param str name: Name of the converter. If not None, this name is used to register the converter in the Flask app. Example:: api.register_converter( UUIDConverter, 'string', 'UUID', name='uuid') @blp.route('/pets/{uuid:pet_id}') api.register_blueprint(blp) This registers the converter in the Flask app and in the internal APISpec instance. Once the converter is registered, all paths using it will have corresponding path parameter documented with the right type and format. The `name` parameter need not be passed if the converter is already registered in the app, for instance if it belongs to a Flask extension that already registers it in the app. """
