I'm not sure about the relationship between InactiveLoco and Locomotive. Is it bad design how a subclass contains another subclass of the same base class? I thought I had read something like this on the Wiki but couldn't find it. --Elliot Fisher 09:31, 6 October 2008 (UTC)

- InactiveLoco is definitely an Adapter rather than a Proxy. A Proxy does not provide a different interface, it exists to transparently perform additional actions. An Adapter on the other hand often does not perform any or many additional actions, it exits to provide an alternative interface and often simply passes messages on to the adaptee. --Aidan 21:21, 4 October 2009 (UTC)
