Detailed Description

Filter to take explicit <style> and <script> tags and outline them to files.

Member Function Documentation

virtual void net_instaweb::JsOutlineFilter::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(), except RenderDone(), which (if in use) happens after Flush().

Reimplemented from net_instaweb::EmptyHtmlFilter.

ScriptUsage net_instaweb::JsOutlineFilter::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::JsOutlineFilter::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.
