Hi,
GNATCOLL.JSON question:
I want to test if an object "state" (JSON_Value) is like "{"name":"blabla"}"
which is almost an empty (sub-)object and which I want to avoid to include
in the (super-)object "cell".
The following code/hack works:
------------------------------------------------------------
declare
a : constant JSON_Value := Clone(state);
begin
a.unset_field(Field_Name => "name");
if not a.is_empty then
cell.Set_Field(Field_Name => "state",Field => state);
end if;
end;
-------------------------------------------------------------
I assume this is clumsy. Is there a shorter way?
