Member Function Documentation

virtual void net_instaweb::RewrittenContentScanningFilter::EndDocument ( )
virtual

Note: EndDocument will be called immediately before the last Flush call. (which also means that in the RewriteDriver use it is called before rendering for the last flush window).

Reimplemented from net_instaweb::EmptyHtmlFilter.

virtual void net_instaweb::RewrittenContentScanningFilter::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::RewrittenContentScanningFilter::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.
