Detailed Description

Allows to modify the tracks to implement toy models.

This class derives from AliTrackContainer. It allows to select tracks based and modify their momenta according to some toy modeling. At the moment only pt scaling is implemented

Constructor & Destructor Documentation

AliTrackContainerToyModel::AliTrackContainerToyModel ( )

This is the default constructor, used for ROOT I/O purposes.

Definition at line 26 of file AliTrackContainerToyModel.cxx.

AliTrackContainerToyModel::AliTrackContainerToyModel ( const char *  name)

This is the standard named constructor.

Parameters

Bool_t AliTrackContainerToyModel::GetAcceptMomentum ( TLorentzVector &  mom,
Int_t  i 
) const
virtual

Fills a TLorentzVector with the monentum infomation of the \( i^{th} \) accepted particle in the container, using a global mass hypothesis. In case the provided index is out of range, or the particle under the index is not accepted, false is returned as return value. Overrides the AliTrackContainer methods by applying a pT scaling factor to the TLorentzVector.

Parameters
[out]momMomentum vector of the accepted particle
[in]iIndex to check
Returns
True if the request was successfull, false otherwise

Reimplemented from AliTrackContainer.

Fills a TLorentzVector with the momentum information of the \( i^{th} \) particle in the container, using a global mass hypothesis. In case the provided index is out of range, false is returned as return value. Overrides the AliTrackContainer methods by applying a pT scaling factor to the TLorentzVector.

Parameters
[out]momMomentum vector of the \( i^{th} \) particle in the array

Bool_t AliTrackContainerToyModel::GetMomentumFromTrack ( TLorentzVector &  mom,
const AliVTrack *  track,
Double_t  mass 
) const
virtual

Retrieve momentum information of a track and fill a TLorentzVector with it. In case the optional parameter mass is provided, it is used as mass hypothesis, otherwise the mass hypothesis from the particle itself is used. Overrides the AliTrackContainer methods by applying a pT scaling factor to the TLorentzVector.

Parameters
[out]momMomentum vector to be filled
[in]trackTrack from which the momentum information is obtained.
[in]mass(Optional) Mass hypothesis
Returns

Bool_t AliTrackContainerToyModel::GetNextAcceptMomentum ( TLorentzVector &  mom)
virtual

Fills a TLorentzVector with the monentum infomation of the next accepted particle in the container, using a global mass hypothesis. In case the iteration reached the end of the array, false is returned as return value. Overrides the AliTrackContainer methods by applying a pT scaling factor to the TLorentzVector.

Deprecated:
Old style iterator - use accept_iterator instead
Parameters
[out]momMomentum vector of the next particle in the array
Returns
True if the request was successfull, false (no more entries) otherwise

Reimplemented from AliTrackContainer.
