Hi,
Can someone explain why in mode objfpc comparing methods only compares
the address, but not the instance?
For example:
a:=TMyClass.Create;
b:=TMyClass.Create;
if @a.test = @b.test then writeln('the same method');
This results in strange behaviors, when using the following code (from
the FCL):
property AfterConnect: TNotifyEvent read FAfterConnect write SetAfterConnect;
procedure TCustomConnection.SetAfterConnect(const AValue: TNotifyEvent);
begin
if FAfterConnect=AValue then exit;
FAfterConnect:=AValue;
end;
