C++ (Cpp) TFile::MakeProject Examples

Example #1

File: alice_esd_split.C Project: My-Source/root

//______________________________________________________________________________
Bool_t alice_esd_loadlib(const char* file, const char* project)
{
   // Make sure that shared library created from the auto-generated project
   // files exists and load it.

   TString lib(Form("%s/%s.%s", project, project, gSystem->GetSoExt()));

   if (gSystem->AccessPathName(lib, kReadPermission)) {
      TFile* f = TFile::Open(file, "CACHEREAD");
      if (f == 0)
         return kFALSE;
      f->MakeProject(project, "*", "++");
      f->Close();
      delete f;
   }
   return gSystem->Load(lib) >= 0;
}

Example #2

File: alice_esd.C Project: chunjie-sam-liu/genome_resequencing_pipeline

//______________________________________________________________________________
Bool_t alice_esd_loadlib(const char* project)
{
   // Make sure that shared library created from the auto-generated project
   // files exists and load it.

   TString lib(Form("%s/%s.%s", project, project, gSystem->GetSoExt()));

   if (gSystem->AccessPathName(lib, kReadPermission)) {
      TFile* f = TFile::Open(esd_file_name, "CACHEREAD");
      if (f == 0)
         return kFALSE;
      TFile *f2 = TFile::Open(esd_friends_file_name, "CACHEREAD");
      TTree *tree = (TTree*) f->Get("esdTree");
      tree->SetBranchStatus ("ESDfriend*", 1);
      f->MakeProject(project, "*", "++");
      f->Close();
      delete f;
   }
   return gSystem->Load(lib) >= 0;
