This graph shows which files directly or indirectly include this file:

Classes
class	ROOT::Internal::TreeUtils::RNoCleanupNotifier
class	ROOT::Internal::TreeUtils::RNoCleanupNotifierHelper

Namespaces
namespace	ROOT
	tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7
namespace	ROOT::Internal
namespace	ROOT::Internal::TreeUtils
	Namespace hosting functions and classes to retrieve tree information for internal use.

Functions
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::pair< std::vector< Long64_t >, Long64_t >	ROOT::Internal::TreeUtils::GetClustersAndEntries (std::string_view treename, std::string_view path)
	Returns the cluster boundaries and number of entries of the input tree.
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.
std::vector< std::string >	ROOT::Internal::TreeUtils::GetTreeFullPaths (const TTree &tree)
std::unique_ptr< TChain >	ROOT::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.
std::pair< bool, std::string >	ROOT::Internal::TreeUtils::TreeUsesIndexedFriends (const TTree &tree)
	Check whether the input tree is using any TTreeIndex.
