Detailed Description

This filter converts from synchronous AdSense snippets (showads.js) to async ones (adsbygoogle.js)

Member Function Documentation

virtual void net_instaweb::MakeShowAdsAsyncFilter::Characters ( HtmlCharactersNode characters)
virtual

If a subclass overloads this function and wishes to use InsertNodeAtBodyEnd(), it needs to make an upcall to this implementation for InsertNodeAtBodyEnd() to work correctly.

Reimplemented from net_instaweb::CommonFilter.

ScriptUsage net_instaweb::MakeShowAdsAsyncFilter::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.
