Class XMLDTDValidator

Implemented Interfaces:
RevalidationHandler, org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDocumentFilter, org.apache.xerces.xni.XMLDocumentHandler, org.apache.xerces.xni.parser.XMLDocumentSource, XMLDTDValidatorFilter
Known Direct Subclasses:
XML11DTDValidator, XMLNSDTDValidator

public class XMLDTDValidator
extends java.lang.Object
implements org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDocumentFilter, XMLDTDValidatorFilter, RevalidationHandler

The DTD validator. The validator implements a document filter: receiving document events from the scanner; validating the content and structure; augmenting the InfoSet, if applicable; and notifying the parser of the information resulting from the validation process.

Formerly, this component also handled DTD events and grammar construction. To facilitate the development of a meaningful DTD grammar caching/preparsing framework, this functionality has been moved into the XMLDTDLoader class. Therefore, this class no longer implements the DTDFilter or DTDContentModelFilter interfaces.

This component requires the following features and properties from the component manager that uses it:
