Detailed Description

Singleton containing and managing the main tree of the go4 analysis. All analysis steps may get and save their events as branches of this tree. The treesource and treestore instances are managing just one branch of this tree for each of their subevents. Branches of this tree might be saved into different root files.

Member Function Documentation

static Bool_t TGo4MainTree::Exists ( )
inlinestatic

True if instance of tree already exists. Used by framework to check if MainTree was created by any treestore/source instance, before the instance is requested. Otherwise framework would create maintree without need.

Int_t TGo4MainTree::IncCurrentIndex ( )

void TGo4MainTree::Update ( )

Update the tree entry information without processing any branch. i.e. increment the entry counter with all branches disabled. To be called by framework once within the event loop.
