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

name	Name of the particle collection

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]	mom	Momentum vector of the accepted particle
[in]	i	Index to check

Returns: True if the request was successfull, false otherwise

Reimplemented from AliTrackContainer.

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

virtual

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]	mom	Momentum vector of the \( i^{th} \) particle in the array
[in]	i	Index of the particle to check

Returns: True if the request was successful, false otherwise

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]	mom	Momentum vector to be filled
[in]	track	Track from which the momentum information is obtained.
[in]	mass	(Optional) Mass hypothesis

Returns

Reimplemented from AliTrackContainer.

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] mom Momentum vector of the next particle in the array

Returns: True if the request was successfull, false (no more entries) otherwise

Reimplemented from AliTrackContainer.

Bool_t AliTrackContainerToyModel::GetNextMomentum ( TLorentzVector & mom )

virtual

Fills a TLorentzVector with the momentum information of the next particle in the container, using a global mass hypothesis. In case the iterator 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.
