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.
