Class Description

This class provides the behavior for the list page and select page Direct to Web templates, specifically BASListPage, NEUListPage, and WOLListPage. The classes for these components inherit directly from D2WListPage and define no additional methods or variables.

D2WPlainListPage also inherits from this class.

Most of the methods in this class are accessed (via the EOKeyValueCoding interface defined in the EOControl framework) from the Direct to Web template's bindings (.wod) file. If you create a Direct to Web template from a list page or a select page, you can invoke the methods in this class in the same way. See the "Direct to Web" chapter of WebObjects Tools and Techniques for more information about creating a Direct to Web template.
