Selector for PROOF I/O benchmark test.

For the I/O benchmark, event files are read in and histograms are filled. For memory clean-up, dedicated files large enough to clean up memory cache on the machine are read in. Or memory clean-up can be accompolished by system call on Linux machine inside SlaveBegin(..) which should be much faster the reading in large files.

virtual

Reimplemented from TSelector.

◆ Notify()

virtual Bool_t TSelEvent::Notify ( )

virtual

This method must be overridden to handle object notification.

Reimplemented from TSelector.

◆ Process()

Bool_t TSelEvent::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.

◆ SlaveBegin()

void TSelEvent::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 129 of file TSelEvent.cxx.

◆ SlaveTerminate()

void TSelEvent::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 254 of file TSelEvent.cxx.

◆ Terminate()

void TSelEvent::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.
