This is a common pattern I’m finding when working with generics in FPC. In the
example below there is an equals comparison that needs to be checked but for
some types such as records there is no default operator overload so I need to
add one for every record that will be specialized in the class.
Is there a way around this? I’d like to just skip the comparison for
specialized types that can’t be compared if possible.
type
generic TCollection<T> = class
procedure AddValue (value: T);
end;
procedure TCollection.AddValue (value: T);
begin
// comparison operator doesn't exist for records so I get compiler
errors if I specialize TCollection<> with a record type
if value = T then
;
end;
