Definition: External.C:236
Base task in the EMCAL framework.
void SetUseAliAnaUtils(Bool_t b, Bool_t bRejPilup=kTRUE)
AliEmcalList * fOutput
!output list
virtual bool Run()
Run function. This is the core function of the analysis and contains the user code. Therefore users have to implement this function.
void UserCreateOutputObjects()
Main initialization function on the worker.
