Public Methods

Method	Description
AttachFilesOrPaths ( IEnumerable paths ) : void	Loads the provided files from all of the specified paths.
DeleteFiles ( List files ) : void	Deletes the list of files from the database.
DetatchFiles ( List files ) : void	Detaches the list of files from the database.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
GetAllAttachedFiles ( ) : List	Enumerates all of the files attached to the database.
HardCommit ( ) : void	Forces a commit to the disk subsystem. Once this returns, the data will not be lost due to an application crash or unexpected shutdown. Hard commits can take 100ms or longer depending on how much data has to be committed. This requires two consecutive hardware cache flushes.
SoftCommit ( ) : void	Forces a soft commit on the database. A soft commit only commits data to memory. This allows other clients to read the data. While soft committed, this data could be lost during an unexpected shutdown. Soft commits usually occur within microseconds.
