# Interface GeneratedMessageV3.BuilderParent (3.19.4)

    protected static interface GeneratedMessageV3.BuilderParent extends AbstractMessage.BuilderParent

TODO(xiaofeng): remove this after b/29368482 is fixed. We need to move this
interface to AbstractMessage in order to versioning GeneratedMessageV3 but
this move breaks binary compatibility for AppEngine. After AppEngine is
fixed we can exclude this from google3.
