|
|
* The BO-layer implementes some extra features on top of the so-layer:
|
|
|
|
|
* 1) It handles links to not already existing entries. This is used by the eTemplate link-widget, which allows to
|
|
|
|
|
* setup links even for new / not already existing entries, before they get saved.
|
|
|
|
|
* In that case you have to set the first id to 0 for the link-static function and pass the array returned in that id
|
|
|
|
|
* (not the return-value) after saveing your new entry again to the link static function.
|
|
|
|
|
* 2) Attaching files: they are saved in the vfs and not the link-table (!).
|
|
|
|
|
* Attached files are stored under $vfs_basedir='/infolog' in the vfs!
|
|
|
|
|
* 3) It manages the link-registry, in which apps can register themselfs by implementing some hooks
|
|
|
|
|
* 4) It notifies apps, who registered for that service, about changes in the links their entries
