[PATCH] qom/object: enable setter for uint types |
|
Date: |
Sun, 17 Nov 2019 15:50:32 +0000 |
Traditionally, the uint-specific property helpers only offer getters.
When adding object (or class) uint types, one must therefore use the
generic property helper if a setter is needed.
This enhances the uint-specific property helper APIs by adding a
'readonly' field and modifying all users of that API to set this
parameter to true. If 'readonly' is false, though, the helper will add
an automatic setter for the value.
