示例1: Process
//_____________________________________________________________________________
Bool_t ProofEventProc::Process(Long64_t entry)
{
// The Process() function is called for each entry in the tree (or possibly
// keyed object in the case of PROOF) to be processed. The entry argument
// specifies which entry in the currently loaded tree is to be processed.
// It can be passed to either TTree::GetEntry() or TBranch::GetEntry()
// to read either all or the required parts of the data. When processing
// keyed objects with PROOF, the object is already loaded and is available
// via the fObject pointer.
//
// This function should contain the "body" of the analysis. It can contain
// simple or elaborate selection criteria, run algorithms on the data
// of the event and typically fill histograms.
// WARNING when a selector is used with a TChain, you must use
// the pointer to the current TTree to call GetEntry(entry).
// The entry is always the local entry number in the current tree.
// Assuming that fChain is the pointer to the TChain being processed,
// use fChain->GetTree()->GetEntry(entry).
if (fEntMin == -1 || entry < fEntMin) fEntMin = entry;
if (fEntMax == -1 || entry > fEntMax) fEntMax = entry;
