Simple version of CombineCssFilter.

Concatenates all CSS files loaded from <link> tags into a single output. Does not consider barriers, statements, absolutification, etc.


Member Function Documentation

virtual bool net_instaweb::CombiningFilter::ComputeOnTheFly ( ) const [inline, virtual]

If this method returns true, the data output of this filter will not be cached, and will instead be recomputed on the fly every time it is needed. (However, the transformed URL and similar metadata in CachedResult will be kept in cache).

The default implementation returns false.

Reimplemented from net_instaweb::RewriteFilter.

virtual const UrlSegmentEncoder* net_instaweb::CombiningFilter::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::CombiningFilter::Flush ( ) [inline, 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().

Reimplemented from net_instaweb::EmptyHtmlFilter.

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::CombiningFilter::StartDocumentImpl ( ) [inline, 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.
