Hi,
There is something I don't understand with TDirectory::Get(). Suppose I've
a
TNamed object and a object from a class that I've derived from
TNamed. Both objects have been added in gDirectory using
gDirectory->Add(). The object names are respectively "tnamed" and
"tnamedd". Why do I get this result:
gDirectory->Get("tnamed") returns a pointer to the TNamed object
gDirectory->Get("tnamedd") returns a NULL pointer (not a pointer to the
TNamed derived object)
If both objects are written a TKey into gDirectory, I get valid pointers
with the 2 lines
I get also this problem with ROOT classes. With a TObjString object, I get
a valid pointer. With a TMatrixD object, I get a NULL
pointer.
TDirectory::FindObject() behaves the same way (with objects in memory of
course)
Thank you!
