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

+ *
+ * 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
