6 | // The following methods are defined in this file: | |
7 | // Begin(): called everytime a loop on the tree starts, | |
8 | // a convenient place to create your histograms. | |
9 | // SlaveBegin(): called after Begin(), when on PROOF called only on the | |
10 | // slave servers. | |
11 | // Process(): called for each event, in this function you decide what | |
12 | // to read and fill your histograms. | |
13 | // SlaveTerminate: called at the end of the loop on the tree, when on PROOF | |
14 | // called only on the slave servers. | |
15 | // Terminate(): called at the end of the loop on the tree, | |
16 | // a convenient place to draw/fit your histograms. | |
17 | // | |
18 | // To use this file, try the following session on your Tree T: | |
19 | // | |
20 | // Root > T->Process("esdAna.C") | |
21 | // Root > T->Process("esdAna.C","some options") | |
