That's not too bad. I'm still not a fan of TVector as a class from a memory and efficiency point of view, but you are at least using it consistently.
When calling Free on a class instance, you do not need to check that the class instance is not nil first. Free does that already.
System.pasNot much else to comment on really. The class design seems to be pretty good.Code:procedure TObject.Free; begin if Self <> nil then Destroy; end;
