Class Description

This class provides the behavior for the master-detail page Direct to Web tempaltes, specifically BASMasterDetailPage, NEUMasterDetailPage, and WOLMasterDetailPage. The classes for these pages inherit directly from D2WMasterDetailPage and define no additional methods or variables.

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 master-detail 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.
