Detailed Description

Reduced information about a reconstructed jet.

Class with reduced jet information for the reduced jet tree. For a jet, the following information is stored:

  1. 4-momentum vector of the jet
  2. list of reduced constituents found by the jet clustering algorithm
  3. list of all charged particles with reduced information within a certain distance to the main jet axis.

Constructor & Destructor Documentation

HighPtTracks::AliReducedJetInfo::AliReducedJetInfo ( )

Definition at line 31 of file AliReducedJetInfo.cxx.

HighPtTracks::AliReducedJetInfo::AliReducedJetInfo ( double  px,
double  py,
double  pz,
double  e 
)

Main constructor of the reduced jet information of a reconstuced jet. Initializes the 4-momentum vector. Also containers for associated particles and jet constituents are allocated.

Parameters
pxx-component of the 4-momentum vector
pyy-component of the 4-momentum vector
pzz-component of the 4-momentum vector
eReconstructed jet energy

Definition at line 52 of file AliReducedJetInfo.cxx.

HighPtTracks::AliReducedJetInfo::AliReducedJetInfo ( const AliReducedJetInfo &  ref)

Copy constructor, initializes a new jet info from a reference object. For constituents and associated particles a deep copy is performed, meaning the new object keeps ownership over its pointers.

Parameters
refReference object for the copy

Definition at line 74 of file AliReducedJetInfo.cxx.

HighPtTracks::AliReducedJetInfo::~AliReducedJetInfo ( )
virtual

Destructor, cleaning object. All containers are deleted.

Definition at line 136 of file AliReducedJetInfo.cxx.

Member Function Documentation

void HighPtTracks::AliReducedJetInfo::AddConstituent ( AliReducedJetConstituent *  con)

Adds a constituent (charged or neutral) as associated by the clustering algorithm to the reduced jet.

Parameters
conJet constituent to be added

void HighPtTracks::AliReducedJetInfo::FillLorentzVector ( TLorentzVector &  vec) const

Fills a TLorentzVector with jet 4-momentum.

Parameters
vecThe vector to be filled.

void HighPtTracks::AliReducedJetInfo::Set ( double  px,
double  py,
double  pz,
double  e 
)
inline

Set the jet 4-momentum vector

Parameters
pxx-component of the 4-momentum vector
pyy-component of the 4-momentum vector
pzz-component of the 4-momentum vector
ejet energy
