Member Function Documentation

virtual void net_instaweb::LoggingFilter::IEDirective ( HtmlIEDirectiveNode *  directive )

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.

void net_instaweb::LoggingFilter::LogStatistics

(

StatisticsLog *

statistics_log

)

const

Logging, diffing, and aggregation.

Report all statistics

virtual void net_instaweb::LoggingFilter::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.
