47 | /* | 46 | public class FriendsModule : ISharedRegionModule, IFriendsModule |
48 | This module handles adding/removing friends, and the the presence | ||
49 | notification process for login/logoff of friends. | ||
50 | |||
51 | The presence notification works as follows: | ||
52 | - After the user initially connects to a region (so we now have a UDP | ||
53 | connection to work with), this module fetches the friends of user | ||
54 | (those are cached), their on-/offline status, and info about the | ||
55 | region they are in from the MessageServer. | ||
56 | - (*) It then informs the user about the on-/offline status of her friends. | ||
57 | - It then informs all online friends currently on this region-server about | ||
58 | user's new online status (this will save some network traffic, as local | ||
59 | messages don't have to be transferred inter-region, and it will be all | ||
60 | that has to be done in Standalone Mode). | ||
61 | - For the rest of the online friends (those not on this region-server), | ||
62 | this module uses the provided region-information to map users to | ||
63 | regions, and sends one notification to every region containing the | ||
64 | friends to inform on that server. | ||
65 | - The region-server will handle that in the following way: | ||
66 | - If it finds the friend, it informs her about the user being online. | ||
67 | - If it doesn't find the friend (maybe she TPed away in the meantime), | ||
68 | it stores that information. | ||
69 | - After it processed all friends, it returns the list of friends it | ||
70 | couldn't find. | ||
71 | - If this list isn't empty, the FriendsModule re-requests information | ||
72 | about those online friends that have been missed and starts at (*) | ||
73 | again until all friends have been found, or until it tried 3 times | ||
74 | (to prevent endless loops due to some uncaught error). | ||
75 | |||
76 | NOTE: Online/Offline notifications don't need to be sent on region change. | ||
77 | |||
78 | We implement two XMLRpc handlers here, handling all the inter-region things | ||
79 | we have to handle: | ||
80 | - On-/Offline-Notifications (bulk) | ||
81 | - Terminate Friendship messages (single) | ||
