- * Okay, it's nice that this was documented and all, but I at least understood very little
- * of it, so I'm going to attempt to explain the data structures in here a bit more.
- *
- * For efficiency, many data structures are kept.
- *
- * The first is a global list `watchentries':
- * hash_map<irc::string, std::deque<User*> >
- *
- * That is, if nick 'w00t' is being watched by user pointer 'Brain' and 'Om', <w00t, (Brain, Om)>
- * will be in the watchentries list.
- *
- * The second is that each user has a per-user data structure attached to their user record via Extensible:
- * std::map<irc::string, std::string> watchlist;
- * So, in the above example with w00t watched by Brain and Om, we'd have:
- * Brain-
- * `- w00t
- * Om-
- * `- w00t
- *
- * Hopefully this helps any brave soul that ventures into this file other than me. :-)

-/* This module has been refactored to provide a very efficient (in terms of cpu time)
- * implementation of /WATCH.
- *
- * To improve the efficiency of watch, many lists are kept. The first primary list is
- * a hash_map of who's being watched by who. For example:
- *
- * KEY: Brain ---> Watched by: Boo, w00t, Om
- * KEY: Boo ---> Watched by: Brain, w00t
- *
- * This is used when we want to tell all the users that are watching someone that
- * they are now available or no longer available. For example, if the hash was
- * populated as shown above, then when Brain signs on, messages are sent to Boo, w00t
- * and Om by reading their 'watched by' list. When this occurs, their online status
- * in each of these users lists (see below) is also updated.
- *
- * Each user also has a seperate (smaller) map attached to their User whilst they
- * have any watch entries, which is managed by class Extensible. When they add or remove
- * a watch entry from their list, it is inserted here, as well as the main list being
- * maintained. This map also contains the user's online status. For users that are
- * offline, the key points at an empty string, and for users that are online, the key
- * points at a string containing "users-ident users-host users-signon-time". This is
- * stored in this manner so that we don't have to FindUser() to fetch this info, the
- * users signon can populate the field for us.
- *
- * For example, going again on the example above, this would be w00t's watchlist:
- *
- * KEY: Boo ---> Status: "Boo brains.sexy.babe 535342348"
- * KEY: Brain ---> Status: ""
- *
- * In this list we can see that Boo is online, and Brain is offline. We can then
- * use this list for 'WATCH L', and 'WATCH S' can be implemented as a combination
- * of the above two data structures, with minimum CPU penalty for doing so.
- *
- * In short, the least efficient this ever gets is O(n), and thats only because
- * there are parts that *must* loop (e.g. telling all users that are watching a
- * nick that the user online), however this is a *major* improvement over the
- * 1.0 implementation, which in places had O(n^n) and worse in it, because this
- * implementation scales based upon the sizes of the watch entries, whereas the
- * old system would scale (or not as the case may be) according to the total number
- * of users using WATCH.
