Does it make sense to use some special value (zero or -1) to mean
uninitialized? That way could at least preserve the type.
But the special value is invalid for keyboard configurations. If it is
set in keyboard properties, users may get confused. So I prefer 'null'
to mean uninitialized. Thanks.
This is a valid point. However, if I understood correctly, these are
values set in the SMF manifest. You can have comments in the manifest
explaining the uninitialized value. Moreover, you can leverage SMF
templates to validate the values, but if you use astring, you cannot
validate ranges.
I don't understand why a missing value in the SMF repository can not
be inferred as uninitialized. Could you please elaborate that?
Hi Antonello,
In fact, in this case I've already used missing value(null, value='') to
mean uninitialized. You can see reference [2] in the PSARC material for
details. For the data type, it seems a missing value is invalid for
'count' type. And for 'integer' type, a missing value is treated as 0.
So I use astring to store the values. When users configure keyboard
using system/keymap service, kbd will be called to validate the
values(ranges) and set the values into kernel. Thanks.
