All Implemented Interfaces:

Cloneable, com.webobjects.directtoweb.generation.DTWGeneration, EditRelationshipPageInterface, NSKeyValueCoding, NSKeyValueCoding.ErrorHandling, NSKeyValueCodingAdditions, NSValidation, Serializable, WOActionResults

Direct Known Subclasses:

BASEditRelationshipPage, NEUEditRelationshipPage, WOLEditRelationshipPage

public class D2WEditRelationshipPage

extends D2WPage

implements EditRelationshipPageInterface, com.webobjects.directtoweb.generation.DTWGeneration

The D2WEditRelationshipPage class provides the behavior for the edit-relationship page Direct to Web templates: BASEditRelationshipPage, NEUEditRelationshipPage, and WOLEditRelationshipPage. The classes for these components inherit directly from D2WEditRelationshipPage and define no additional methods or variables.

Most methods 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 an edit-relationship page, you can invoke the methods in this class in the same way.
