Why do you think, that D2006 will have generics?
D2006 <> D11=D2007
How will Delphi handle the following case with overloads and different types:
If it is handled as a kind of macro, then it is no problem. The type of
data is known at compile time.
If the generic is "pre"compiled (which is maybe necesary if you need
access to privates) then I fear some runtime logic has to be added to
call the correct procedure. IE. something like
case TypeInfo(Data) of
StringType: Show(Data);
IntegerType: Show(Data);
end;
Marc
unit test;
interface
type
List<T> = class
data : T;
constructor(aData: T);
procedure dump;
end;
implementation
procedure show(i:integer);overload;
begin
end;
procedure show(s:string);overload;
begin
end;
constructor List<T>(aData: T);
begin
Data := aData;
end;
procedure List<T>.Dump;
begin
Show(Data);
end;
end.
