java.lang.Object

org.jaxen.saxpath.helpers.DefaultXPathHandler

All Implemented Interfaces:

XPathHandler

public class DefaultXPathHandler
extends java.lang.Object
implements XPathHandler

Default base class for SAXPath event handlers. This class is available as a convenience base class for SAXPath applications: it provides a default do-nothing implementation for all of the callbacks in the core SAXPath handler class, XPathHandler. Application writers can extend this class when they need to implement only part of the XPathHandler interface. Parser writers can instantiate this class to provide default handlers when the application has not supplied its own.
