public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId) throws SAXException
DefaultHandler
Always return null, so that the parser will use the system identifier provided in the XML document. This method implements the SAX default behaviour: application writers can override it in a subclass to do special translations such as catalog lookups or URI redirection.

publicId
- The public identifer, or null if none is
available.systemId
- The system identifier provided in the XML
document.
SAXException
- Any SAX exception, possibly
wrapping another exception.EntityResolver.resolveEntity(java.lang.String, java.lang.String)
public void characters(char[] ch, int start, int length) throws SAXException
DefaultHandler
By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).

wrapping another exceptionContentHandler.characters(char[], int, int)
public void endDocument() throws SAXException
DefaultHandler
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).
