virtual void net_instaweb::CssCombineFilter::DetermineEnabled | ( | ) | [virtual] |
Override DetermineEnabled so that filters that use the DOM cohort of the property cache can enable writing of it in the RewriterDriver. Filters inheriting from RewriteDriver that use the DOM cohort should override UsePropertyCacheDomCohort to return true.
Reimplemented from net_instaweb::RewriteFilter.
virtual const UrlSegmentEncoder* net_instaweb::CssCombineFilter::encoder | ( | ) | const [inline, virtual] |
All RewriteFilters define how they encode URLs and other associated information needed for a rewrite into a URL. The default implementation handles a single URL with no extra data. The filter owns the encoder.
Reimplemented from net_instaweb::RewriteFilter.
virtual void net_instaweb::CssCombineFilter::Flush | ( | ) | [virtual] |
Notifies the Filter that a flush is occurring. A filter that's generating streamed output should flush at this time. A filter that's mutating elements can mutate any element seen since the most recent flush; once an element is flushed it is already on the wire to its destination and it's too late to mutate. Flush is initiated by an application calling HttpParse::Flush().
Flush() is called after all other handlers during a HttpParse::Flush(), except RenderDone(), which (if in use) happens after Flush().
Reimplemented from net_instaweb::EmptyHtmlFilter.
virtual void net_instaweb::CssCombineFilter::IEDirective | ( | HtmlIEDirectiveNode * | directive | ) | [virtual] |
Called for an IE directive; typically used for CSS styling. See http://msdn.microsoft.com/en-us/library/ms537512(VS.85).aspx
Reimplemented from net_instaweb::EmptyHtmlFilter.
virtual RewriteContext* net_instaweb::CssCombineFilter::MakeRewriteContext | ( | ) | [virtual] |
Generates a RewriteContext appropriate for this filter. Default implementation returns NULL. This must be overridden by filters. This is used to implement Fetch.
Reimplemented from net_instaweb::RewriteFilter.
virtual void net_instaweb::CssCombineFilter::StartDocumentImpl | ( | ) | [virtual] |
Overload these implementer methods: Intentionally left abstract so that implementers don't forget to change the name from Blah to BlahImpl.
Implements net_instaweb::CommonFilter.
const char net_instaweb::CssCombineFilter::kCssFileCountReduction[] [static] |
Name of statistics variable used to record # of CSS file fetches avoided due to combining.
