virtual void net_instaweb::DelayImagesFilter::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::DelayImagesFilter::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.

ScriptUsage net_instaweb::DelayImagesFilter::GetScriptUsage ( ) const

inlineoverridevirtual

Note: there is also kRequiresScriptExecutionFilterSet in rewrite_options.cc, which identifies filters that will leave broken pages if javascript is disabled, and hence require noscript handing. The set of filters that CanInjectScripts is larger, as it includes filters that might inject beacons or other optional functionality that is not page-critical.

Implements net_instaweb::HtmlFilter.

virtual void net_instaweb::DelayImagesFilter::StartDocumentImpl ( )

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.
