Hi,

In Delphi you can overload the Explicit operator. This makes is possible to have a type TTypeX and TTypeY and cast one into the other. To do that, implement an operator overloader: operator Explicit(const AValue: TTypeX): TTypeY.

  // implement converstio from TTypeX to TTypeY.

Then you can do stuff like
var
  tx: TTypeX;
  ty: TTypeY;
begin
  tx := TTypeX.Create;
  ty := TTypeY(tx);
end;

Is something like this possible in FPC?

Kind regards,
Birger

I don't know. If you don't get an answer, it may be useful to ask on the fpc-pascal mailing list, that is a better place for such questions:

overload the := operator instead. Search for the free pascal docs on
operator overloading.
