java.lang.Object

net.sourceforge.htmlunit.cyberneko.filters.DefaultFilter

All Implemented Interfaces:

HTMLComponent, org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.xni.parser.XMLDocumentFilter, org.apache.xerces.xni.parser.XMLDocumentSource, org.apache.xerces.xni.XMLDocumentHandler

Direct Known Subclasses:

NamespaceBinder

public class DefaultFilter
extends Object
implements org.apache.xerces.xni.parser.XMLDocumentFilter, HTMLComponent

This class implements a filter that simply passes document events to the next handler. It can be used as a base class to simplify the development of new document filters.
