[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH RFC V2 06/10] libxl_json: allow basic JSON type objects generation
The original logic is that basic JSON types (number, string and null) must be an element of JSON map or array. This assumption doesn't hold true anymore when we need to return basic JSON types. Returning basic JSON types is required for parsing number, string and null objects back into libxl__json_object.
