◆ Notify()

virtual Bool_t TSelHandleDataSet::Notify ( )
inlinevirtual

This method must be overridden to handle object notification.

Reimplemented from TSelector.

Definition at line 48 of file TSelHandleDataSet.h.

◆ Process()

Bool_t TSelHandleDataSet::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 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.
