Function documentation

TSelectorEntries(TTree* tree = 0, const char* selection = 0)
 Default, constructor.
TSelectorEntries(const char* selection)
void Begin(TTree* tree)
 The Begin() function is called at the start of the query.
 When running with PROOF Begin() is only called on the client.
 The tree argument is deprecated (on PROOF 0 is passed).
void SlaveBegin(TTree* tree)
 The SlaveBegin() function is called after the Begin() function.
 When running with PROOF SlaveBegin() is called on each slave server.
 The tree argument is deprecated (on PROOF 0 is passed).
Int_t GetEntry(Long64_t entry, Int_t getall = 0)
read entry
void Init(TTree* tree)
 The Init() function is called when the selector needs to initialize
 a new tree or chain. Typically here the branch addresses and branch
 pointers of the tree will be set.
 It is normaly not necessary to make changes to the generated
 code, but the routine can be extended by the user if needed.
 Init() will be called many times when running on PROOF
 (once per file to be processed).
Bool_t Notify()
 This function is called at the first entry of a new tree in a chain.
Bool_t 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 TSelectorEntries::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.

 The processing can be stopped by calling Abort().

 Use fStatus to set the return value of TTree::Process().

 The return value is currently not used.
void SetSelection(const char* selection)
set the selection expression
void SlaveTerminate()
 The SlaveTerminate() function is called after all entries or objects
 have been processed. When running with PROOF SlaveTerminate() is called
 on each slave server.
void Terminate()
 The Terminate() function is the last function to be called during
 a query. It always runs on the client, it can be used to present
 the results graphically or save the results to file.
Int_t Version()
{ return 2; }
Long64_t GetSelectedRows()
{ return fSelectedRows; }
void SetOption(const char* option)
{ fOption = option; }
void SetObject(TObject* obj)
{ fObject = obj; }
TList * GetOutputList()
{ return fOutput; }
