void ROOT::Internal::TreeUtils::ClearMustCleanupBits (TObjArray &branches)
 Reset the kMustCleanup bit of a TObjArray of TBranch objects (e.g.
std::vector< std::string > ROOT::Internal::TreeUtils::ExpandGlob (const std::string &glob)
 Expands input glob into a collection of full paths to files.
std::vector< std::string > ROOT::Internal::TreeUtils::GetFileNamesFromTree (const TTree &tree)
ROOT::TreeUtils::RFriendInfo ROOT::Internal::TreeUtils::GetFriendInfo (const TTree &tree, bool retrieveEntries=false)
std::vector< std::string > ROOT::Internal::TreeUtils::GetTopLevelBranchNames (TTree &t)
 Get all the top-level branches names, including the ones of the friend trees.
static void GetTopLevelBranchNamesImpl (TTree &t, std::unordered_set< std::string > &bNamesReg, std::vector< std::string > &bNames, std::unordered_set< TTree * > &analysedTrees, const std::string friendName="")
std::vector< std::string > ROOT::Internal::TreeUtils::GetTreeFullPaths (const TTree &tree)
std::unique_ptr< TChainROOT::Internal::TreeUtils::MakeChainForMT (const std::string &name, const std::string &title)
 Create a TChain object with options that avoid common causes of thread contention.
std::vector< std::unique_ptr< TChain > > ROOT::Internal::TreeUtils::MakeFriends (const ROOT::TreeUtils::RFriendInfo &finfo)
 Create friends from the main TTree.
void ROOT::Internal::TreeUtils::RecursiveGlob (TList &out, const std::string &glob)
 Recursively expand the glob to take care of potential wildcard specials for subdirectories in the glob.
