[Neutral General]

In Delphi:

Delphi-Quellcode:

procedure TForm1.swapTwoValues<T>(var Value1, Value2: T);
var tmp: T;
begin
  tmp := Value1;
  Value1 := Value2;
  Value2 := tmp;
end;

Aufruf:

Delphi-Quellcode:

swapTwoValues<Integer>(someInt1, someInt2);
swapTwoValues<String>(someStr1, someStr2);
swapTwoValues<TMyRecord>(someRec1, someRec2);
