+// The class definition in esdClus.h has been generated automatically

+// framework see $ROOTSYS/README/README.SELECTOR or the ROOT User Manual.

+// The following methods are defined in this file:
+//    Begin():        called everytime a loop on the tree starts,
+//                    a convenient place to create your histograms.
+//    SlaveBegin():   called after Begin(), when on PROOF called only on the
+//                    slave servers.
+//    Process():      called for each event, in this function you decide what
+//                    to read and fill your histograms.
+//    SlaveTerminate: called at the end of the loop on the tree, when on PROOF
+//                    called only on the slave servers.
+//    Terminate():    called at the end of the loop on the tree,
+//                    a convenient place to draw/fit your histograms.
