[Qemu-devel] [PATCH v4 04/18] qapi: add QAPI visitor core |
Date: |
Wed, 22 Jun 2011 07:59:25 -0500 |
Base definitions/includes for Visiter interface used by generated
visiter/marshalling code.
Includes a GenericList type. Our lists require an embedded element.
Since these types are generated, if you want to use them in a different
type of data structure, there's no easy way to add another embedded
element. The solution is to have non-embedded lists and that what this is.
