Member Function Documentation

void net_instaweb::InsertAmpLinkFilter::DetermineEnabled ( GoogleString * disabled_reason )

overridevirtual

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.

ScriptUsage net_instaweb::InsertAmpLinkFilter::GetScriptUsage ( ) const

inlineoverridevirtual

Todo:: TODO(jmarantz): Make an explicit filter method declaring this filter as something we don't want to run in an AMP document. In the meantime, we can induce disabling for AMP documents with this:

Implements net_instaweb::HtmlFilter.

void net_instaweb::InsertAmpLinkFilter::StartDocumentImpl ( )

overridevirtual

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.
