Member Function Documentation

void net_instaweb::ImageCombineFilter::AddCssBackgroundContext ( const GoogleUrl &  original_url,
const GoogleUrl &  base_url,
Css::Values *  values,
int  value_index,
CssFilter::Context parent,
Css::Declarations *  decls,
MessageHandler *  handler 
)

Attempt to add the CSS background image with (resolved) url original_url to this partnership. We do not take ownership of declarations; it must live until you call Realize() or Reset(). declarations is where we will add the new width and height values; url_value must point to the URL value to be replaced. Will not actually change anything until you call Realize(). This will succeed even in cases when it turns out (later) the image can not be sprited.

virtual const UrlSegmentEncoder* net_instaweb::ImageCombineFilter::encoder ( ) const [inline, protected, virtual]

All RewriteFilters define how they encode URLs and other associated information needed for a rewrite into a URL. The default implementation handles a single URL with no extra data. The filter owns the encoder.

Reimplemented from net_instaweb::RewriteFilter.

If there is any work to do, registers the RewriteContext created by Reset(). If there isn't, cleans it up.

virtual void net_instaweb::ImageCombineFilter::StartDocumentImpl ( ) [inline, protected, 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.
