Hi,
I am writing a Tree class which have the following skeleton:
generic TTree<T> = class
private
FItems: TList;
public
...
end;
The FItems variable is used to store Children of current node. My question
is:
Shall I store TTree in FItems or @TTree? My understanding is:
If a variable obj is an TObject, it is actually a pointer, which stores
the address of the "real" object structure.
If I add @obj into FItems, then I am storing the address of the obj
variable, i.e.:
FItems[i] --> obj --> (real object structure)
However, if I add obj into FItems, I am storing the address of the object
structure, i.e.:
FItems[i] -----> (real object structure)
^
|
obj
Is that correct? In the 2nd case, is there any "reference counter" for
TObject which counts how many "pointers" are pointing to the structure?
Thanks.
