54 * The server list in InspIRCd is maintained as two structures
55 * which hold the data in different ways. Most of the time, we
56 * want to very quicky obtain three pieces of information:
58 * (1) The information on a server
59 * (2) The information on the server we must send data through
60 * to actually REACH the server we're after
61 * (3) Potentially, the child/parent objects of this server
63 * The InspIRCd spanning protocol provides easy access to these
64 * by storing the data firstly in a recursive structure, where
65 * each item references its parent item, and a dynamic list
66 * of child items, and another structure which stores the items
67 * hashed, linearly. This means that if we want to find a server
68 * by name quickly, we can look it up in the hash, avoiding
69 * any O(n) lookups. If however, during a split or sync, we want
70 * to apply an operation to a server, and any of its child objects
71 * we can resort to recursion to walk the tree structure.
