Dear all,
I need to process a tree including objects, discribed in shared library.
I have the following code:
> {
> gSystem->Load("libEvent.so");
>
> gROOT->GetPluginManager()->AddHandler("TVirtualStreamerInfo",
> "*",
> "TStreamerInfo",
> "RIO",
> "TStreamerInfo()");
>
> TFile *f = new TFile("test1.root");
>
> TTree *t = (TTree*)gDirectory->Get("t");
>
> Int_t np;
> t->SetBranchAddress("np",&np);
> std::vector<BEPoint> *data;
> t->SetBranchAddress("fBEPoints",&data);
>
> Long64_t nentries = t->GetEntries();
>
> std:::cout<<"N="<<nentries<<std::endl;
> Long64_t ientry = t->LoadTree(1);
> Int_t nbytes=0;
> nbytes += t->GetEntry(1);
>
> std:::cout<<"np="<<np<<std::endl;
> std:::cout<<"size="<<data->size()<<std::endl;
> }
and the followinf output:
> root [0] .x loadtest.C
> N=1000
> np=2
> Error: illegal pointer to class object data 0x0 3101 loadtest.C:27:
> *** Interpreter error recovered ***
So it seems that data of type Int_t (np) are loaded correctly, but data of type std::vector (data) are not loaded. What is wrong?
Thanks,

Thanks, but this doesn’t help. Now the code is:
> {
> gSystem->Load("libEvent.so");
>
> gROOT->GetPluginManager()->AddHandler("TVirtualStreamerInfo",
> "*",
> "TStreamerInfo",
> "RIO",
> "TStreamerInfo()");
>
> TFile *f = new TFile("test1.root");
>
> TTree *t = (TTree*)gDirectory->Get("t");
>
> Int_t np;
> t->SetBranchAddress("np",&np);
> std::vector<BEPoint> *data = 0;
> t->SetBranchAddress("fBEPoints",&data);
>
> Long64_t nentries = t->GetEntries();
>
> std:::cout<<"N="<<nentries<<std::endl;
> Long64_t ientry = t->LoadTree(1);
> Int_t nbytes=0;
> nbytes += t->GetEntry(1);
>
> std:::cout<<"np="<<np<<std::endl;
> std:::cout<<"size="<<data->size()<<std::endl;
> }
and the output is:
> root [0] .x loadtest.C
> N=1000
> np=2
> Error: illegal pointer to class object data 0x0 3101 loadtest.C:27:
> *** Interpreter error recovered ***
So it seems data are not loaded.
Maybe your tree has no “fBEPoints” branch. Try:
t->Print();
Try also:
if (data) std::cout << "size=" << data->size() << std::endl;
else std::cout << "no data in tree" << std::endl;
BTW. When you post “source code” or “output” here, do remember to enclose them into two lines which contain just three characters ``` (see how your posts have been edited above).

Most of data, which are objects (not numbers or arrays) are not included in class - only fHeader is included. Why?
Which ROOT version are you using?@pcanal as I remember that some older versions had some problems with objects.

Just now tried ROOT 5.34/36 - the same situation.
So, try the newest ROOT 6.
