java.lang.Object
  org.foray.demo.embed.tools.EasyContentHandlerProxy

All Implemented Interfaces:

ContentHandler

public class EasyContentHandlerProxy
extends Object
implements ContentHandler

This class is an implementation of ContentHandler which acts as a proxy to another ContentHandler and has the purpose to provide a few handy methods that make life easier when generating SAX events.
Note: This class is only useful for simple cases with no namespaces.
