◆ Begin()

void TSelHist::Begin ( TTree * tree )

The Begin() function is called at the start of the query.

TClass * TSelHist::IsA ( ) const

inlineoverridevirtual

Returns: TClass describing current object

Reimplemented from TSelector.

Definition at line 60 of file TSelHist.h.

◆ Process()

Bool_t TSelHist::Process ( Long64_t entry )

overridevirtual

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.
