0106   //information is retrieved during beginRun, during the Event,
0107   //or during both. This is needed to declare which EventSetup
0108   //products are consumed. In the future, this will affect

0110   //work, but there is some performance advantage to only
0111   //declaring the necessary one. With only a few exceptions,

0113   //functions in this class getting EventSetup data), so EventSetup
0114   //objects might be retrieved in both periods. The argument defaults
