Could I do some RTL magic on a record to loop over its fields and set them to
another record by name? In the example below I want to set all the fields in
TRecA to matching named fields in TRecB. Just curious if we can do this
automatically using RTL.
type
TRecA = record
a: string;
b: string;
end;
type
TRecB = record
a: string;
b: string;
c: integer;
d: integer;
end;
for field in recA.GetFields do
recB.GetFieldByName(field.name).value := field.value
If you make sure that any variable of tRecB is declared first, you can use
Var RecB : tRecB;
RecA : tRedA ABSOLUTE RecB;
Quite obviously, it doesn't work the other way around as tRecB is larger
than tRecA...
