Subject: [PATCH] util: json: Split out array->strinlist conversion from
|
|
virJSONValueObjectGetStringArray
|
|
|
|
Introduce virJSONValueArrayToStringList which does only the conversion
|
|
from an array to a stringlist.
|
|
|
|
This will allow refactoring the callers to be more careful in case when
|
|
they want to handle the existance of the member in the parent object
|
|
differently.
|
|
