const std::string &  filename = "AnaTutorial.root" 
)

Constructor.

Cluster/Calorimeter includes.

Jet includes Tracking includes Truth evaluation includes HEPMC truth includes Fun4All includes ROOT includes C++ includes This class demonstrates the construction and use of an analysis module within the sPHENIX Fun4All framework. It is intended to show how to obtain physics objects from the analysis tree, and then write them out to a ROOT tree and file for further offline analysis. Constructor of module

Initialize variables and trees so we don't accidentally access memory that was never allocated
