◆ Init()

void TSelEventGen::Init ( TTree * tree )

overridevirtual

Reimplemented from TSelector.

◆ IsA()

TClass * TSelEventGen::IsA ( ) const

inlineoverridevirtual

Returns: TClass describing current object

Reimplemented from TSelector.

Definition at line 74 of file TSelEventGen.h.

◆ Notify()

Bool_t TSelEventGen::Notify ( )

overridevirtual

This method must be overridden to handle object notification (the base implementation is no-op).

Different objects in ROOT use the Notify method for different purposes, in coordination with other objects that call this method at the appropriate time.

For example, TLeaf uses it to load class information; TBranchRef to load contents of referenced branches TBranchRef; most notably, based on Notify, TChain implements a callback mechanism to inform interested parties when it switches to a new sub-tree.

Reimplemented from TSelector.

◆ Print()

void TSelEventGen::Print ( Option_t * option = "" ) const

overridevirtual

This method must be overridden when a class wants to print itself.

Reimplemented from TObject.

Definition at line 486 of file TSelEventGen.cxx.

◆ Process()

Bool_t TSelEventGen::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 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.

Reimplemented from TSelector.

Definition at line 326 of file TSelEventGen.cxx.

◆ SetInputList()

void TSelEventGen::SetInputList ( TList * input )

inlineoverridevirtual

Reimplemented from TSelector.

Definition at line 68 of file TSelEventGen.h.

inlineoverridevirtual

Reimplemented from TSelector.

Definition at line 66 of file TSelEventGen.h.

◆ SlaveBegin()

void TSelEventGen::SlaveBegin ( TTree * tree )

overridevirtual

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 89 of file TSelEventGen.cxx.

◆ SlaveTerminate()

void TSelEventGen::SlaveTerminate ( void )

overridevirtual

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 459 of file TSelEventGen.cxx.

◆ Streamer()

void TSelEventGen::Streamer ( TBuffer & R__b )

overridevirtual

Stream an object of class TObject.

Reimplemented from TSelector.

◆ StreamerNVirtual()

void TSelEventGen::StreamerNVirtual ( TBuffer & ClassDef_StreamerNVirtual_b )

inline

Definition at line 74 of file TSelEventGen.h.

◆ Terminate()

void TSelEventGen::Terminate ( void )

overridevirtual

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 480 of file TSelEventGen.cxx.

Int_t TSelEventGen::Version ( ) const
