Hello, I just can't seem to get some things straight about the Interface and Component system used in Twisted. Take for example Manhole; The Interface defines three methods; console, receiveExplorer and listCapabilities: class IManholeClient(components.Interface): def console(self, list_of_messages): def receiveExplorer(self, xplorer): def listCapabilities(self): In twisted/manhole/ui/gtk2manhole.py The class ManholeClient _claims_ to implements this interface: class ManholeClient(components.Adapter, pb.Referenceable): __implements__ = (IManholeClient,) Well, strictly seen it doesn't. It defines the methods remote_console, remote_receiveExplorer and remote_listCapabilities (!). It does not define either of console, receiveExplorer and listCapabilities. What is the use of claiming it does implement it? Probably there is something about interfaces used in the perspective broker that I don't understand. Why isn't there a different notation for remote and local interfaces? Like ILocalManholeClient and IRemoteManholeClient, wherein the first is like the current IManholeClient, and the second with methods remote_ prefixes. Wladimir
