42 * @brief Defines the interface to manage the Admin Users/Groups and Override caches.
44 * The administration system is more of a volatile cache than a system. It is designed to be
45 * temporary rather than permanent, in order to compensate for more storage methods. For example,
46 * a flat file might be read into the cache all at once. But a MySQL-based system might only cache
47 * admin permissions when that specific admin connects.
49 * The override cache is the simplest to explain. Any time an override is added, any existing
50 * and all future commands will gain a new access level set by the override. If unset, the default
51 * access level is restored. This cache is dynamically changeable.
53 * The group cache contains, for each group:
54 * 1] A set of inherent flags - fully readable/writable.
55 * 2] An immunity table - insertion and retrieval only.
56 * 3] An override table - insertion and retrieval only.
57 * Individual groups can be invalidated entirely. It should be considered an expensive
58 * operation, since each admin needs to be patched up to not reference the group.
60 * For more information, see the SourceMod Development wiki.
