Examples of DelegatingHandler

de.danet.an.util.sax.DelegatingHandler
DelegatingHandler waits for predefined elements and, if encountered, installs associated handlers on the {@link HandlerStack HandlerStack}.
org.jboss.virtual.plugins.context.DelegatingHandler
A delegating VirtualFileHandler that allows for overriding the delegate parent and name. One usecase is a link which roots another VFSContext under a different parent and name. @author Scott.Stark@jboss.org @version $Revision:$
