3 custom embedded classes in TTree

ROOT
1

Hi,

I have these custom classes I’m trying to store in a TTree. I have a event class that has a STL vector of pulse class which also holds a STL vector of a pmt class. No matter what setting on the TTree splitlevel I give, I can’t seem to get the pmt class info into the tree. I made a very simple example that demonstrates the problem.
CustomClassesTree.C (772 Bytes)
I processed the file like so …

root [0] .x CustomClassesTree.C++ 
Info in <TUnixSystem::ACLiC>: creating shared library /home/j0n0/Desktop/temp/./CustomClassesTree_C.so
In file included from /home/j0n0/Desktop/temp/CustomClassesTree_C_ACLiC_dict.h:34,
                 from /home/j0n0/Desktop/temp/CustomClassesTree_C_ACLiC_dict.cxx:17:
/home/j0n0/Desktop/temp/./CustomClassesTree.C: In member function ‘void C::StreamerNVirtual(TBuffer&)’:
/home/j0n0/Desktop/temp/./CustomClassesTree.C:30: warning: declaration of ‘b’ shadows a member of 'this'
root [1] TFile file("CustomClassTree.root")
root [2] tree->StartViewer()
File name : CustomClassTree.root

And got this

When I did the tree->MakeClass(“myclass”), I expected the ‘b_a’ variable in the example to be a double array but instead get the vector b_a which is commented out. How do I store and access the Class A properly?

Thanks,
Surge

[quote]How do I store and access the Class A properly?[/quote]Collections with a collections can not be split (too many variable sizes). The data is stored correctly in the list, however you can not access it with MakeClass (because MakeClass gives access only to the split members) I recommend you try use MakeProxy instead.
