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.

void TGo4BackStore::Reset

(

Bool_t

onlyclearflag = kFALSE

Dynamic list might reset backstore after processing. If onlyclearflag is true, do not reset tree, but just unmark the "backstore was reset" bit.
