TTree and custom classes

jlam · January 5, 2013, 3:35am

Hi,
I’m working on a project where I store data in a custom class and store the object in a TTree for later access and processing. My custom class extends off TObject, includes the ClassDef and ClassImp functions, along with functions to modify and/or retrieve stored data (which includes Int_t, Double_t, string, and vector).
The problem I’m running into is that after associating the object with a branch, saving data to the object, calling Fill() and Write(), no data is saved.
Without posting the full code (I can post full code if needed), this is what I roughly have:

TFile *Events = new TFile("CoreasEvents.root", "RECREATE");
  if(Events->IsOpen())
{
      CoreasEvent *testEvent = new CoreasEvent;
      TTree *eventTree = new TTree("Event List", "Collection of CoreasEvent Objects" );
      eventTree->Branch("CoreasEvent", "CoreasEvent", &testEvent, 64000, 99);
      //code for grabbing and storing into testEvent object
      eventTree->Fill();
      eventTree->Write("eventTree");
}

I’ve been compiling the code using CINT if it matters at all.
I’ve looked through various tutorials on how to use TTree with custom objects but I can’t find out what’s wrong with my code. Any help would be appreciated.

Maybe you could try:
root [0] TFile *f = TFile::Open(“CoreasEvents.root”);
root [1] f->ls();
root [2] eventTree->Print();

Hi,
That method was one of the methods I used to verify no data was saved. One curious thing though is that the structure of the object is saved, but not the data it contains.
Just in case though, this is how I’ve been trying to access the class after it’s saved:

CoreasEvent *buf = new CoreasEvent;
TBranch *branch = eventTree->GetBranch("CoreasEvent");
branch->SetAddress(&buf);
buf->print(); //print() is is simply a function that calls cout and prints some basic values stored in the class, used to verify whether or not any data was saved

One thing I wanted to ask is that, when looking through the documentation, I see both GetEntry and GetEvent. What is the difference between these two functions?
Another thing to note is that in some examples I noticed split level 0 was used, but whenever I attempt to use split level 0, the program crashes with a segfault. I was wondering why that might be.
Thank you.

Could you, please, execute the commands that I gave you and post the output here (note: you may need to load some shared library which provides the dictionary for your “CoreasEvent” class before you do this).

BTW. It seems that you try to “buf->print();” without prior calling “branch->GetEntry(SomeEntryNumber);” or “eventTree->GetEntry(SomeEntryNumber);” (where “0 <= SomeEntryNumber < eventTree->GetEntries()”) .

P.S. See TTree::GetEvent and/or TBranch::GetEvent methods descriptions if you want to learn what it does (and compare them to TTree::GetEntry and/or TBranch::GetEntry methods descriptions, if you like).

As far as my code goes, I had GetEntry in my source code but forgot to include it in my post.

There’s one branch that looks suspicious to me: “Br 21 :fgIsA : TClass*”.
Is it possible that you run your code which creates the tree (and the root file) as interpreted?
In particular, is it possible that you did not create a compiled dictionary for your “CoreasEvent” class?
Could you try (and post the output here):
root […] .class CoreasEvent

How would I go about compiling a dictionary for my class? My experience with this is somewhat limited.

root [0] .L CoreasEvent.cpp++
… then load and execute the code which creates the tree (this code can be run as interpreted, I believe) …

I noticed that if I loaded CoreasEvent.cpp before running the code that creates the tree, I also had to load CoreasEvent.cpp before accessing the file otherwise it would complain about a lack of dictionary Warning in <TClass::TClass>: no dictionary for class CoreasEvent is available

Aside from that, this is the output I get when I load CoreasEvent.cpp before accessing the root file

You need “++” -> see my previous post (it MUST be pre-compiled by ACLiC).
Note: your tree is broken -> you need to recreate it after you load a compiled dictionary for your “CoreasEvent” class.

jlam · January 6, 2013, 8:46pm

Just to clarify, in order to pre-compile with ACLiC, would I just run “.L CoreasEvent.cpp+”? Or would I run it for the script that creates the tree with include links to CoreasEvent.cpp?
I’m following this guide: root.cern.ch/download/doc/ROOTUs … 07s09.html

Wile_E_Coyote · January 6, 2013, 8:51pm

I prefer “++”, but you may use just “+”, if you like.
You should “.L CoreasEvent.cpp++” first.
Then you can “.L” any code (either as interpreted or as compiled) that uses this class -> note however, this code must NOT #include “CoreasEvent.cpp”, it should #include “CoreasEvent.h” only.

jlam · January 6, 2013, 9:13pm

Attempting to run “.L CoreasEvent.cpp++” returns the error

Error in <ACLiC>: Compilation failed!

All the errors seem to point to lines where 2D vectors were used. Is there any way to fix this?

Wile_E_Coyote · January 6, 2013, 9:18pm

These are c++ source code errors. You need to fix them.
Try (fix all reported errors and warnings):
root-config --cxx --cflags -O2 -W -Wall -c CoreasEvent.cpp

jlam · January 6, 2013, 9:30pm

Okay, I will try that.
I see a lot of errors that look like this: CoreasEvent.h:9: error: âDouble_tâ does not name a type
What does it mean when it says does not name a type? For reference, that specific error points to this line: Double_t energy; in the class declaration. It also gives similar errors to the other lines in the class declaration.
Would this method require me to add include lines for classes from the root library?

Wile_E_Coyote · January 6, 2013, 9:33pm

You said you were inheriting from a “TObject”, so you should have #include “TObject.h” which should also be sufficient for a “Double_t” and so.

jlam · January 7, 2013, 7:48pm

Adding #include “Tobject.h” resolved issues with 2D vectors and strings (#include being present). This is the output I’m currently getting when i run root-config --cxx --cflags -O2 -W -Wall -c CoreasEvent.cpp

All the errors seem to point to string and vector.
For reference I am running the code on gcc 4.1.2

Either (recommended):
std::string<…> …;
std::vector<…> …;
or (acceptable):
using std::string;
using std::vector;
or (discouraged):
using namespace std;

I’m not quite sure how I managed to forget to add using namespace std but that happens occasionally I suppose.
I managed to fix all the errors and successfully save data to the root file. Thank you very much Wile!
