Class HTMLPublisherListener

java.lang.Object

com.neurosys.seo.ajax.HTMLPublisherListener

All Implemented Interfaces:

ChangeListener<Object[]>, ChangeListenerTransfomer<Object[]>, Serializable, EventListener, org.apache.commons.collections.Transformer, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class HTMLPublisherListener
extends Object
implements ChangeListenerTransfomer<Object[]>, org.springframework.context.ApplicationContextAware

For on call this listener will publish a given working URL to a HTML page using AjaxUrlToHTMLTransformer do that a crawler may access the published file as per Google Specs

Note: How the Crawler will may the ugly URL (with _escaped_fragment_ param) to the published file is open to implementation. However, if we want to trigger any automated sequence of action we may do so by overriding autoMap(String, URI) method.
