All Implemented Interfaces:

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

Direct Known Subclasses:

BASErrorPage, NEUErrorPage, WOLErrorPage

public class D2WErrorPage

extends D2WPage

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

The D2WErrorPage class provides behavior for the error page Direct to Web templates, specifically BASErrorPage, NEUErrorPage, and WOLErrorPage. The classes for these pages inherit directly from D2WErrorPage and define no additional methods or variables. Most methods are accessed, via the EOKeyValueCoding interface defined in EOControl, from the bindings (.wod) file of the Direct to Web template. If you create a Direct to Web template from an error page, you can invoke the methods in this class in the same way.
