ALife.Creatur.Database.CachedFileSystemInternal
Description
A module containing private CachedFileSystem internals. Most developers should use CachedFileSystem instead. This module is subject to change without notice.
- data CachedFSDatabase r = CachedFSDatabase {
- database :: FSDatabase r
- cache :: [r]
- maxCacheSize :: Int
- withFSDB :: Monad m => StateT (FSDatabase r) m a -> StateT (CachedFSDatabase r) m a
- fromCache :: Record r => String -> StateT (CachedFSDatabase r) IO (Maybe r)
- addToCache :: SizedRecord r => r -> StateT (CachedFSDatabase r) IO ()
- deleteByKeyFromCache :: SizedRecord r => String -> StateT (CachedFSDatabase r) IO ()
- deleteFromCache :: SizedRecord r => r -> StateT (CachedFSDatabase r) IO ()
- trimCache :: SizedRecord r => StateT (CachedFSDatabase r) IO ()
- trim :: SizedRecord r => Int -> [r] -> [r]
- listSize :: SizedRecord r => [r] -> Int
- mkCachedFSDatabase :: FilePath -> Int -> CachedFSDatabase r
