caproto.server.server.
NestedPvproperty
(get=None, put=None, startup=None, shutdown=None, *, scan=None, name=None, dtype=None, value=None, max_length=None, alarm_group=None, doc=None, read_only=None, field_spec=None, fields=None, record=None, **cls_kwargs)[source]¶ Nested pvproperty which allows decorator usage in parent class
Without using this for the SubGroups, using @subgroup.prop.getter causes the parent class to see multiple pvproperties - one defined on the subgroup, and one returned from pvproperty.getter. This class fixes that by returning the expected class - the parent (i.e., the subgroup)
- Bonus points if you understood all of that.
… scratch that, bonus points to me, I think.
