Detailed Description

Class for reading output of GGSHadrIntAction.

This class provides methods to read the information about hadronic interactions as saved by GGSHadrIntAction.

Definition at line 26 of file GGSTHadrIntReader.h.

Member Function Documentation

void GGSTHadrIntReader::GetEntry ( Long64_t  entry )

virtual

@ brief Reads the specified entry from the hadronic interaction branch.

Parameters

entry

The desired entry.

Implements GGSTChainReader.

Definition at line 37 of file GGSTHadrIntReader.cpp.

                                               {
  if (entry != _hadrIntChain->GetEntries()) {
    _hadrIntChain->GetEntry(entry);
  }
}

GGSTHadrIntInfo * GGSTHadrIntReader::GetInelastic

(

Int_t

trackID = 1

)

Retrieves the inelastic interaction for the given primary.

Parameters

trackID

The track ID of the primary particle.

Returns

Pointer to inelastic interaction info (NULL if no inelastic interaction is found).

Definition at line 44 of file GGSTHadrIntReader.cpp.

                                                              {

  GGSTHadrIntInfo *interaction;
  for (int i = 0; i < _inelastic->GetEntries(); i++) {
    interaction = (GGSTHadrIntInfo *)(_inelastic->At(i));
    if (interaction->originalTrackID == trackID)
      return interaction;
  }

  return NULL;
}

Int_t GGSTHadrIntReader::GetNQuasiElastic

(

Int_t

trackID = 1

)

Retrieves the number of quasi-elastic interactions for the given primary.

Parameters

trackID

The track ID of the primary particle.

Returns

The number of quasi-elastic interactions.

Definition at line 58 of file GGSTHadrIntReader.cpp.

                                                       {

  Int_t nInt = 0;
  for (int i = 0; i < _quasiElastic->GetEntries(); i++) {
    if (((GGSTHadrIntInfo *)(_quasiElastic->At(i)))->originalTrackID == trackID)
      nInt++;
  }

  return nInt;
}

GGSTHadrIntInfo * GGSTHadrIntReader::GetQuasiElastic	(	Int_t	nQE,
		Int_t	trackID = 1
	)

Retrieves a quasi-elastic interaction for the given primary.

Note that ordering is random, so first interaction is not guaranteed to be happened before the second, and so on.

Parameters

nQE	The desired quasi-elastic interaction.
trackID	The track ID of the primary particle.

Returns

Pointer to quasi-elastic interaction info.

NULL if no quasi-elastic interaction is found or if nQE >= GetNQuasiElastic.

Definition at line 71 of file GGSTHadrIntReader.cpp.

                                                                            {

  Int_t nInt = 0;
  GGSTHadrIntInfo *interaction;
  for (int i = 0; i < _quasiElastic->GetEntries(); i++) {
    interaction = (GGSTHadrIntInfo *)(_quasiElastic->At(i));
    if (interaction->originalTrackID == trackID) {
      if (nInt == nQE)
        return interaction;
      else
        nInt++;
    }
  }

  return NULL;
}

bool GGSTHadrIntReader::SetChain ( TChain *  hadrIntChain )

virtual

Sets the chain.

This method sets the hadronic interactions chain, from which the informations will be read.

Parameters

hadrIntChain

The chain containing the hadronic interactions.

Implements GGSTChainReader.

                                                     {

  _hadrIntChain = hadrIntChain;
  if (_hadrIntChain->SetBranchAddress("inelastic", &_inelastic) == 0 &&
      _hadrIntChain->SetBranchAddress("quasiElastic", &_quasiElastic) == 0) {
    return true;
