The filter class has a class method `filter` which gets run before or after the action, depending on if it's a before or after filter. Classes used as around filters can also use the same `filter` method, which will get run in the same way. The method must `yield` to execute the action. Alternatively, it can have both a `before` and an `after` method that are run before and after the action. +Again, this is not an ideal example for this filter, because it's not run in the scope of the controller but gets the controller passed as an argument.
