Constructor & Destructor Documentation

TSelHist::TSelHist ( )
TSelHist::~TSelHist ( )
virtual

Destructor.

Definition at line 54 of file TSelHist.cxx.

Member Function Documentation

void TSelHist::Begin ( TTree tree)
virtual

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).

Reimplemented from TSelector.

Definition at line 84 of file TSelHist.cxx.

virtual TList* TSelHist::GetOutputList ( ) const
inlinevirtual

Reimplemented from TSelector.

Definition at line 58 of file TSelHist.h.

Bool_t TSelHist::Process ( Long64_t  entry)
virtual

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 TSelHist::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.

Reimplemented from TSelector.

Definition at line 267 of file TSelHist.cxx.

virtual void TSelHist::SetInputList ( TList input)
inlinevirtual

Reimplemented from TSelector.

Definition at line 57 of file TSelHist.h.

virtual void TSelHist::SetObject ( TObject obj)
inlinevirtual

Reimplemented from TSelector.

Definition at line 56 of file TSelHist.h.

virtual void TSelHist::SetOption ( const char *  option)
inlinevirtual

Reimplemented from TSelector.

Definition at line 55 of file TSelHist.h.

void TSelHist::SlaveBegin ( TTree tree)
virtual

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).

Reimplemented from TSelector.

Definition at line 156 of file TSelHist.cxx.

void TSelHist::SlaveTerminate ( void  )
virtual

The SlaveTerminate() function is called after all entries or objects have been processed.

When running with PROOF SlaveTerminate() is called on each slave server.

Reimplemented from TSelector.

Definition at line 306 of file TSelHist.cxx.

void TSelHist::Terminate ( void  )
virtual

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.

Reimplemented from TSelector.

Definition at line 315 of file TSelHist.cxx.

virtual Int_t TSelHist::Version ( ) const

Reimplemented from TSelector.
