Member Function Documentation

virtual void net_instaweb::FixReflowFilter::DetermineEnabled ( GoogleString *  disabled_reason )

virtual

Invoked by rewrite driver where all filters should determine whether they are enabled for this request. The re-writer my optionally set disabled_reason to explain why it disabled itself, which will appear in the debug output.

Reimplemented from net_instaweb::EmptyHtmlFilter.

virtual void net_instaweb::FixReflowFilter::StartDocument ( )

virtual

Starts a new document. Filters should clear their state in this function, as the same Filter instance may be used for multiple HTML documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.

virtual void net_instaweb::FixReflowFilter::StartElement ( HtmlElement *  element )

virtual

When an HTML element is encountered during parsing, each filter's StartElement method is called. The HtmlElement lives for the entire duration of the document.

Todo:

TODO(jmarantz): consider passing handles rather than pointers and reference-counting them instead to save memory on long documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.
