Detailed Description

Event store to keep the last n events in a TTree which is _not_ saved to a file.

Allows to view the event structure from the tree and to perform TTree::Draw actions on the last events by means of dynamic list. May contain ring buffer functionality.

Member Data Documentation

const Text_t TGo4BackStore::fgcEVBRANCHNAME = "Go4EventBranch." [static]

Standard go4 name of the branch used in all treestore and treesource implementations. Definition at line 25 of file TGo4BackStore.cxx.

const Text_t TGo4BackStore::fgcTREESUF = "xTree" [static]
