-/**
- * @file lldiskcache.h
- * @brief The disk cache implementation declarations.
- *
- * @Description:
- * This code implements a disk cache using the following ideas:
- * 1/ The metadata for a file can be encapsulated in the filename.
-      The filenames will be composed of the following fields:
-        Prefix:     Used to identify the file as a part of the cache.
-                    An additional reason for using a prefix is that it
-                    might be possible, either accidentally or maliciously
-                    to end up with the cache dir set to a non-cache
-                    location such as your OS system dir or a work folder.
-                    Purging files from that would obviously be a disaster
-                    so this is an extra step to help avoid that scenario.
-        ID:         Typically the asset ID (UUID) of the asset being
-                    saved but can be anything valid for a filename
-        Extra Info: A field for use in the future that can be used
-                    to store extra identifiers - e.g. the discard
-                    level of a JPEG2000 file
-        Asset Type: A text string created from the LLAssetType enum
-                    that identifies the type of asset being stored.
-        .asset      A file extension of .asset is used to help
-                    identify this as a Viewer asset file
- * 2/ The time of last access for a file can be updated instantly
- *    for file reads and automatically as part of the file writes.
- * 3/ The purge algorithm collects a list of all files in the
- *    directory, sorts them by date of last access (write) and then
- *    deletes any files based on age until the total size of all
- *    the files is less than the maximum size specified.
- * 4/ An LLSingleton idiom is used since there will only ever be
- *    a single cache and we want to access it from numerous places.
- * 5/ Performance on my modest system seems very acceptable. For
- *    example, in testing, I was able to purge a directory of
- *    10,000 files, deleting about half of them in ~ 1700ms. For
- *    the same sized directory of files, writing the last updated
- *    time to each took less than 600ms indicating that this
- *    important part of the mechanism has almost no overhead.
