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.

Reset()

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