Member Function Documentation

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().

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

Todo:
TODO(mdsteele): Should we try to maintain the nested structure of the conditionals, in the same way that we maintain nesting of elements?

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.

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.
