Hello,

TDirectory and TFolder both manage tree like structures.
There are many differences between the two classes.
TDirectory manages hierachical structures in memory AND disk.
TFolder knows only about memory.
TDirectory always owns the objects. This is not the case
with a TFolder.
I've tried the following code:
TList* list=new TList;
TObjString* buf=NULL;
for(Int_t i = 0; i<cardbuf.Count();i++){
buf=new TObjString;
*buf=cardbuf[i][formulaindex].Data();
list->Add(buf);
}
gDirectory->Add(list);
gDirectory->Delete("*;*");
delete list;
If TDirectory owned always its objects, it should fail on last line
because it would try to free memory that is already freed. However, it
doesn't. Why?
Where can I find detailed documentation about ownership of
List/Array/Tree/Directory classes in Root?
Thank you!
