CodeSnip Old Code (SVN)

Modified methods of IStringList and routines in UUtils.pas that explode a string based on a delimiter to take a string as the delimiter instead of just single characters.

* Changed visibility of some methods: from protected to strict private or protected to strict protected.
* Clarified comments.

Added new constant to IntfPreview.pas that specifies size of margin to use in previews and changed FrHTMLPreview.pas and FrMemoPreview.pas to use the constant instead of literal value.

Removed unused units from uses clauses.

* Remove factory classes
* Removed TDatabaseType
* Removed all implementation section

* Modified TSnippetsIOFactory re removal of TDatabaseType: Replaced TSnippetsIOFactory.CreateLoader with TSnippetsIOFactory.CreateMainDBLoader and TSnippetsIOFactory.CreateUserDBLoader methods
* Modified re removal of data IO factories with direct construction data reader and writer objects.

Modified code that loads databases in line with changes to TSnippetsIOFactory.

Modified objects that read and write main and user databases, including nul reader used when one of the databases doesn't exist:
* Removed code that registered reader / writer - now redundant.
* Moved class declarations from implementation to interface sections of unit.
* Except for nul reader, removed references and dependencies on deleted TDatabaseType. Additionally, path to database directory now passed in constructor rather than being determined within read class.

Modified units to work with new garbage collector, TGC from new UGC unit, instead of TAutoObjFree object from removed UAutoFree unit.

Replaced UAutoFree.pas with UGC.pas which provides a garbage collector static class that can be used to manage the lifetime of objects.
