process

public abstract ResolvedSiteMapItem process(ResolvedSiteMapItem resolvedSiteMapItem,
                                            javax.servlet.http.HttpServletRequest request,
                                            javax.servlet.http.HttpServletResponse response,
                                            javax.servlet.FilterChain filterChain)

Description copied from interface: FilterChainAwareHstSiteMapItemHandler

Does custom request processing.

This method can return the original resolvedSiteMapItem or a new resolved sitemap item to serve a different one. Or it can return null when it completes the custom request processing by itself so HstFilter needs to stop the request processing.

This method also receives FilterChain instance so it can short circuit HST request processing and continue processing next Filters by invoking filterChain.doFilter(..). If you invoke filterChain.doFilter(..) you must return null from FilterChainAwareHstSiteMapItemHandler.process(org.hippoecm.hst.core.request.ResolvedSiteMapItem, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.FilterChain) because the HST rendering must be short-circuited

Specified by:

process in interface FilterChainAwareHstSiteMapItemHandler

Returns:

a new or the original ResolvedSiteMapItem, or null when the handler did for example already write the entire response and request processing can be stopped

Throws:

HstSiteMapItemHandlerException
