I wonder if these should really all be pure virtual (possibly not in this
patch),  Sami / Haraken WDYT?

[haraken, 2017/01/24 21:49:08]

Yeah, pure virtual sounds nicer.

I prefer keeping EmptyFrameScheduler free of unneeded overrides.

[Sami, 2017/01/26 15:53:34]

I think everything here should be pure virtual. The reason the existing methods
aren't is because the header and the implementation used to live in different
repositories, but we can't use that excuse any longer :)

Fell free to add TODO(alexclarke): Make this API pure virtual

+
   // Tells the scheduler if we are parsing a document on another thread. This
   // tells the scheduler not to advance virtual time if it's using the
   // DETERMINISTIC_LOADING policy.
   virtual void setDocumentParsingInBackground(bool) {}
 
   // Tells the scheduler that the first meaningful paint has occured for this
   // frame.
   virtual void onFirstMeaningfulPaint() {}
 };
 
 }  // namespace blink
