CodeSnip Old Code (SVN)

Changed internal data structure of _TDatabase that maintains list of snippets from _TSnippetList to TDBSnippetsTable.
Made changes to some method bodies re this change.
Modified Save and Load methods to interface with database writer and loader using a _TSnippetList.

Renamed TSnippet class as TSnippetHelper and converted the class into a class helper for TDBSnippet: providing a kind of façade to TDBSnippet.
Redefined TSnippet as a simple alias to TDBSnippet.
Added DB.USnippet to units that require it so that the class helper works.

Converted TSnippet's properties into functions that call inherited read accessor functions.

Extracted nested TTitleComparer and TTitleEqualityComparer from within TSnippet and made classes in their own right, named TSnippetTitleComparer and TSnippetTitleEqualityComparer.
Modified using code re this renaming.

Removed constructor from TSnippet and made it's SetProps method public. Modified affected code as necessary.

Merged remaining method of TSnippetListEx down into _TSnippetList and removed TSnippetListEx.
Modified affected code as necessary.

Merged methods of TSnippetEx down into TSnippet and removed TSnippetEx and TTempSnippet.
Modified affected code as necessary.

Removed redundant constructor and snippet and category list fields from TUserDataProvider.

Revised _TDatabase.UpdateSnippet so it no longer revises TCategory.SnippetIDs property: this is safe because a snippet's categories can no longer be changed.

Moved responsibility for ensuring RequiredModules and XRefs properties of new and updated snippets from TSnippet / TSnippetEx to _TDatabase.
