Summary

Retrieves the list of root items.

Pascal

 functionGetItems: IJvDataItems;

Description

GetItems retrieves the IJvDataItems instance containing the list of root items. Each Data Provider has to have an IJvDataItems instance so you can safely assume that GetItems will never return a nil reference.
Note that it's common for the IJvDataProvider instance to support the IJvDataItems interface as well. This means that if dpvMe contains a reference to IJvDataProvider that: dpvMe.QueryInterface(IJvDataItems, disRoot)
will be the same as: disRoot := dpvMe.GetItems
