Detailed Description

Class deciding whether to store an MC event.

Author

Volker Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e

Since

7 August 2019

The event selection is performed in the method SelectEvent() (nomen est omen...). If this method returns false, the event will not be filled to the output tree.

SelectEvent() can be re-implemented in derived classes. Here, the selection is based on the number of MC data objects (MCTrack, MCPoints), on which the user can specify a minimum by SetMinNofObjects.
