CodeSnip Old Code (SVN)

Removed unused _TDatabase.Clear method.

Removed redundant IDBDataProvider, IDataItemFactory interfaces and TDBDataItemFactory and TUserDataProvider classes.

Removed unused TDatabaseIOFactory.CreateUserDBLoader.
Also removed all unused interfaces and classes.

Modified _TDatabase to set a snippet's modification and creation date as necessary. This fixes a bug in new database output mechanism where modified snippets were not being saved.

Added new TDatabase.Save method that saves database using new native file format.
Removed old Save method from IDatabaseEdit and _TDatabase.
Changed affected code to use TDatabase.Save instead of IDatabaseEdit.Save.

Fixed bugs in TDBNativeReader's DatabaseExists and ValidateSnippetFileHeader methods. Former was always returning False and latter was testing for a master file watermark instead of snippet file.

Changed TDatabaseIOFactory.CreateWriter to return an IDatabaseWriter instance that writes database in native format.
Re-ordered code in TDatabaseIOFactory.CreateLoader.

Fixed bug in TDBNativeWriter code that deletes unwanted files: it could delete all files in directory!

Moved field that records whether database has changed from _TDatabase into TDatabase and created a temporary TDatabase.__Updated property to provide access to the new field to the code that needs it in TDatabase.
Also removed IDatabaseEdit.Updated function and its implementation in TDatabase and added a TDatabase.IsDirty method to perform same role.
Modified TDatabase.Load to clear the dirty flag.
Changed affected code to use the new TDatabase method.

Added new IDatabaseWriter interface and modified TDBNativeWriter to implement it.
