CodeSnip Old Code (SVN)

Removed redundant Assign and IsEqual methods from TSnippetList.
Removed unused TSnippetIDListEx class.

Removed TSnippetList.ToIDList method that was added as a temporary measure at revision 3972.

Removed redundant TODO.

Removed assertions that test for nil snippet after calls to Database.Lookup: this method now raises an exception when the lookup fails (see revision 3984).

Changed TDatabase.Lookup to raise exception if given snippet ID is not found.

Corrected & standardised "snippet not found" assertion messages.

Removed unused _Snippets property from IDatabase and removed related GetSnippets property getter from IDatabase and TDatabase.

Changed data structure that maintains list of selected snippets from TSnippetList to ISnippetIDList and made necessary changes to affected code.
Modified code that calls ISearch.Execute re changes made in USearch unit at revision 3980.

Changed ISearchFilter.Match to take a TSnippetID parameter instead of a TSnippet.
Changed ISearch.Execute's input and output parameters types from TSnippetList to ISnippetIDList.
Made minimal internal changes necessitated by these type changes.

Changed IQuery.Selection property and its associated getter function to return a ISnippetIDList object instead of a TSnippetList.
Provided a minimal implementation of those changes in TQuery: further work needed to rationalise the change.
Modified code that uses IQuery.Selection as necessary.
