Detailed Description

SkFlattenable is the base class for objects that need to be flattened into a data stream for either transport or as part of the key to the font cache.

◆ flatten()

virtual void SkFlattenable::flatten ( SkWriteBuffer &  ) const
inlinevirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead
