Detailed Description

Design of the cache: There is a single KDirListerCache for the whole process. It holds all the items used by the dir listers (itemsInUse) as well as a cache of the recently used items (itemsCached). Those items are grouped by directory (a DirItem represents a whole directory).

KDirListerCache also runs all the jobs for listing directories, whether they are for normal listing or for updates. For faster lookups, it also stores two dicts: a URL -> dirlister holding that URL (urlsCurrentlyHeld) a URL -> dirlister currently listing that URL (urlsCurrentlyListed)

Notify that files have been deleted. This call passes the exact urls of the deleted files so that any view showing them can simply remove them or be closed (if its current dir was deleted) Reimplemented from KDirNotify.

[virtual]

Notify that files have been changed. At the moment, this is only used for new icon, but it could be used for size etc. as well. Note: this is ASYNC so that it can be used with a broadcast
