Detailed Description

A place storing a rewritable URL inside a CSS AST.

Member Function Documentation

virtual bool net_instaweb::CssResourceSlot::CanDirectSetUrl ( )

inlinevirtual

Returns true if DirectSetUrl is supported by this slot (html and css right now).

Reimplemented from net_instaweb::ResourceSlot.

virtual bool net_instaweb::CssResourceSlot::DirectSetUrl ( const StringPiece &  url )

virtual

Update the URL in the slot target without touching the resource. This is intended for when we're inlining things as data: URLs and also for placing the rewritten version of the URL in the slot. The method returns true if it successfully updates the slot target. Resources that are not explicitly authorized will get rejected at this point. Note that if you call this you should also call set_disable_rendering(true), or otherwise the result will be overwritten. Does not alter the URL in any way. Not supported on all slot types — presently only slots representing things within CSS and HTML have this operation (others will DCHECK-fail). Must be called from within a context's Render() method.

Reimplemented from net_instaweb::ResourceSlot.

virtual void net_instaweb::CssResourceSlot::Finished ( )

virtual

Called after all contexts have had a chance to Render. This is especially useful for cases where Render was never called but you want something to be done to all slots.

Reimplemented from net_instaweb::ResourceSlot.

virtual GoogleString net_instaweb::CssResourceSlot::LocationString ( ) const

virtual

Returns a human-readable description of where this slot occurs, for use in log messages.

Implements net_instaweb::ResourceSlot.

virtual void net_instaweb::CssResourceSlot::Render ( )

virtual

Render is not thread-safe. This must be called from the thread that owns the DOM or CSS file. The RewriteContext state machine will only call ResourceSlot::Render() on slots that were optimized successfully, and whose partitions are safely url_relocatable(). (Note that this is different from RewriteContext::Render).

Implements net_instaweb::ResourceSlot.
