All Implemented Interfaces:
Cloneable, com.webobjects.directtoweb.generation.DTWGeneration, ListPageInterface, NSKeyValueCoding, NSKeyValueCoding.ErrorHandling, NSKeyValueCodingAdditions, NSValidation, Serializable, WOActionResults
Direct Known Subclasses:
BASMasterDetailPage, NEUMasterDetailPage, WOLMasterDetailPage

public class D2WMasterDetailPage
extends D2WPage
implements ListPageInterface

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

Most methods are accessed, via the EOKeyValueCoding interface defined in the EOControl framework, from the bindings (.wod) file of the Direct to Web template. 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.
