XML in a Nutshell, 3rd Edition

Name

The XMLFilter Interface

Synopsis

An XMLFilter is an XMLReader that obtains its events from another parent XMLReader, rather than reading it from a text source such as InputStream. Filters can sit between the original source XML and the application and modify data in the original source before passing it to the application. Implementing this interface directly is unusual. It is almost always much easier to use the more complete org.xml.sax.helpers.XMLFilterImpl class instead.

package org.xml.sax;
     
public interface XMLFilter extends XMLReader {
     
  public void      setParent(XMLReader parent);
  public XMLReader getParent(  );
     
}
