I am not quite sure whether my synatx is correct. IMHO explictly defining the
type feels more pascalish. Having more time at hand i have written a much
shorter example code which shows in what way such a type should be defined.
Now I get:
[1004] [EMAIL PROTECTED]:~/Dev/Tests

"Error in a type definition". I do not know whether fpc is supposed to support
this kind if structures. If it is than it is a bug otherwise, no.
Code:
{$mode objfpc}{$h+}
program test3;
uses classes, sysutils;
type
generic TNode = class
type public
PT = ^T;
var private
Data: T;
public
constructor Create;
destructor Destroy; override;
end;
generic TContainer = class
type public
TTNode = specialize TNode;
TPT = TTNode.PT;
var
private
Data: TTNode;
public
constructor Create;
destructor Destroy; override;
function Get: TPT;
end;
constructor TNode.Create;
begin
end;
destructor TNode.Destroy;
begin
inherited Destroy;
end;
constructor TContainer.Create;
begin
end;
destructor TContainer.Destroy;
begin
inherited Destroy;
end;
function Get: TPT;
begin
result := @Data.Data;
end;
begin
end.
