CodeSnip Old Code (SVN)

Made public all protected methods that implement interfaces.

Changed use of "criteria" to "filter" in various identifiers in USearch unit and in using code to better reflect purpose of the names. Made changes to affected code.

Removed redundant interface and method from USearch.
Moved check for a null search from ISearch to ISearchCriteria and changed calling code accordingly.
Revised TSearch and descendants to directly call ISearchCriteria.Match to match required records instead of indirectly. Match abstract method of TSearch removed accordingly.

Changed units which have no specific namespace from MPL v1.1 to MPL v2.0.

Renamed IQuery.CurrentSearch as IQuery.LatestSearch and updated implementing and calling code accordingly

Changed TQuery to descend from TSingleton.

Re-implemented code that records and re-applies nested or refined searches. Previous implementation at r1884 was seriously buggy.

Modified IQuery / TQuery to permit searches to be nested, so one acts on results of previous one.
Also added new IQuery.IsSearchActive method and its implementation.

Standardised svn:mime-type properties to "text/pascal" and svn:eol-style to "native"

Reintegrated v4-dev branch into trunk.
Trunk now contains v4 development tree
