A TSelector object is used by the TTree::Draw, TTree::Scan, TTree::Process to navigate in a TTree and make selections.

It contains the following main methods:

void TSelector::Init(TTree *t). Called every time a new TTree is attached.
void TSelector::SlaveBegin(). Create e.g. histograms in this method. This method is called (with or without PROOF) before looping on the entries in the Tree. When using PROOF, this method is called on each worker node.
void TSelector::Begin(). Mostly for backward compatibility; use SlaveBegin() instead. Both methods are called before looping on the entries in the Tree. When using PROOF, Begin() is called on the client only.
Bool_t TSelector::Notify(). This method is called at the first entry of a new file in a chain.
Bool_t TSelector::Process(Long64_t entry). This method is called to process an entry. It is the user's responsibility to read the corresponding entry in memory (may be just a partial read). Once the entry is in memory one can apply a selection and if the entry is selected histograms can be filled. Processing stops when this function returns kFALSE. This function combines the next two functions in one, avoiding to have to maintain state in the class to communicate between these two functions. See WARNING below about entry. This method is used by PROOF.
Bool_t TSelector::ProcessCut(Long64_t entry). This method is called before processing entry. It is the user's responsibility to read the corresponding entry in memory (may be just a partial read). The function returns kTRUE if the entry must be processed, kFALSE otherwise. This method is obsolete, use Process(). See WARNING below about entry.
void TSelector::ProcessFill(Long64_t entry). This method is called for all selected entries. User fills histograms in this function. This method is obsolete, use Process(). See WARNING below about entry.
void TSelector::SlaveTerminate(). This method is called at the end of the loop on all PROOF worker nodes. In local mode this method is called on the client too.
void TSelector::Terminate(). This method is called at the end of the loop on all entries. When using PROOF Terminate() is call on the client only. Typically one performs the fits on the produced histograms or write the histograms to file in this method.

WARNING when a selector is used with a TChain:

in the Process, ProcessCut, ProcessFill function, you must use the pointer to the current Tree to call GetEntry(entry). entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use fChain->GetTree()->GetEntry(entry);

◆ Abort()

void TSelector::Abort	(	const char *	why,
		EAbort	what = `kAbortProcess`
	)

virtual

Abort processing.

If what = kAbortProcess, the Process() loop will be aborted. If what = kAbortFile, the current file in a chain will be aborted and the processing will continue with the next file, if there is no next file then Process() will be aborted. Abort() can also be called from Begin(), SlaveBegin(), Init() and Notify(). After abort the SlaveTerminate() and Terminate() are always called. The abort flag can be checked in these methods using GetAbort().

TSelector * TSelector::GetSelector ( const char * filename )

static

The code in filename is loaded (interpreted or compiled, see below), filename must contain a valid class implementation derived from TSelector.

If filename is of the form file.C, the file will be interpreted. If filename is of the form file.C++, the file file.C will be compiled and dynamically loaded. The corresponding binary file and shared library will be deleted at the end of the function. If filename is of the form file.C+, the file file.C will be compiled and dynamically loaded. At next call, if file.C is older than file.o and file.so, the file.C is not compiled, only file.so is loaded.

◆ ImportOutput()

void TSelector::ImportOutput ( TList * output )

virtual

Imports the content of 'output' in the internal output list.

Existing content in the output list is discarded (unless found also in 'output'). In particular, if 'output' is nullptr or empty, reset the internal list. On return, the content of 'output' is cleared to avoid double deletion issues. (The caller is responsible of 'output' as container: its content is transferred under the selector ownership).

static

Find out if this is a standard selection used for Draw actions (either TSelectorDraw, TProofDraw or deriving from them).

Definition at line 237 of file TSelector.cxx.

◆ Notify()

Bool_t TSelector::Notify ( )

inlineoverridevirtual

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 TObject.

Reimplemented in TSelEvent, TSelVerifyDataSet, TSelEventGen, TSelHandleDataSet, TSelectorDraw, and TSelectorEntries.

◆ operator=()

TSelector & TSelector::operator= ( const TSelector & )

private

◆ Process()

Bool_t TSelector::Process ( Long64_t )

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 t01::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.

WARNING when a selector is used with a TChain, you must use the pointer to the current TTree to call GetEntry(entry). The entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use: fChain->GetTree()->GetEntry(entry).

Definition at line 360 of file TSelector.cxx.

◆ ProcessCut()

Bool_t TSelector::ProcessCut ( Long64_t )

virtual

This method is called before processing entry.

It is the user's responsibility to read the corresponding entry in memory (may be just a partial read). The function returns kTRUE if the entry must be processed, kFALSE otherwise. This method is obsolete, use Process().

WARNING when a selector is used with a TChain: in the Process, ProcessCut, ProcessFill function, you must use the pointer to the current Tree to call GetEntry(entry). entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use fChain->GetTree()->GetEntry(entry);

Definition at line 313 of file TSelector.cxx.

void TSelector::ProcessFill ( Long64_t )

virtual

This method is called for all selected entries.

User fills histograms in this function. This method is obsolete, use Process().
