Abstract implementation for the IJvDataItemsImages interface.

Pascal

 run\JvDataProvider.pas
 TJvBaseDataItemsImagesImpl = class(TJvDataItemsAggregatedObject, IJvDataItemsImages);


Description

The TJvBaseDataItemsImages class is the abstract base implementation of the IJvDataItemsImages interface. The class itself provides no implementation for interface's methods but rather declares them as abstract virtual methods.
As a descendant of TJvDataItemsAggregatedObject it also provides access to the item list object this extension belongs to (both as interface as well as the implementing object), along with the ContextDestroying notification method, which will be called when a context is destroyed.
You should not instantiate an object of this class but rather one of it's descendants that override the methods for IJvDataItemsImages.
