	container that stores histograms of ThrObj class
namespace	ROOTTools::ThrObjHolder

Functions
void	ROOTTools::ThrObjHolder::Write ()
	Call this function to merge and write histograms in the current open TDirectory (i.e. gDirectory)
void	ROOTTools::ThrObjHolder::Write (const std::string &outputFileName)
	Call this function to merge and write histograms in the specified file which will be overwritten if it already exists, otherwise it will be created.
std::shared_ptr< TH1F >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH1F > *hist, const std::string &directory)
	Not intended for user. Adds TH1F histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH2F >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH2F > *hist, const std::string &directory)
	Not intended for user. Adds TH2F histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH3F >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH3F > *hist, const std::string &directory)
	Not intended for user. Adds TH3F histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH1D >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH1D > *hist, const std::string &directory)
	Not intended for user. Adds TH1D histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH2D >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH2D > *hist, const std::string &directory)
	Not intended for user. Adds TH2D histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH3D >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH3D > *hist, const std::string &directory)
	Not intended for user. Adds TH3D histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH1L >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH1L > *hist, const std::string &directory)
	Not intended for user. Adds TH1L histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH2L >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH2L > *hist, const std::string &directory)
	Not intended for user. Adds TH2L histogram to the corresponding container; this function is called in ThrObj constructor.
std::shared_ptr< TH3L >	ROOTTools::ThrObjHolder::AddHistogram (ROOT::TThreadedObject< TH3L > *hist, const std::string &directory)
	Not intended for user. Adds TH3L histogram to the corresponding container; this function is called in ThrObj constructo.
void	ROOTTools::ThrObjHolder::Clear ()
	Not intended for user. Not intended for user. Clears containers with histogram after histograms were merged and written.
void	ROOTTools::ThrObjHolder::AddTFileDirectory (const std::string &directory, const int thrObjIndex)
	Not intended for user. Adds index of ThrObj to the directory index. This function is called in AddHistogram function.

Detailed Description

Contains useful set of containers to simplify and/or speed up the process of writing multithreaded applications with ROOT TThreadedObject<T> objects.

In order to use these containers libThrObj.so must be loaded
