RaveSetup Class Reference

The RaveSetup class is part of the RaveInterface together with RaveVertexFitter It holds all global options for the RaveVertexFitter and also takes care that stuff like the magnetic field is correctly set up in way Rave can access it. More...

Public Member Functions
void	setBeamSpot (const B2Vector3D &beamSpot, const TMatrixDSym &beamSpotCov)
	The beam spot position and covariance is known you can set it here so that and a vertex in the beam spot should be fitted you can set it here.
void	unsetBeamSpot ()
	unset beam spot constraint
void	reset ()
	frees memory allocated by initialize(). More...

Static Public Member Functions
static RaveSetup *	getInstance ()
	get the pointer to the instance to get/set any of options stored in RaveSetup
static void	initialize (int verbosity=1, double MagneticField=1.5)
	Set everything up so everything needed for vertex fitting is there. More...
static void	Print ()
	Print() writes all RaveSetup member variables to the terminal

Protected Member Functions
	RaveSetup ()
	default constructor
	~RaveSetup ()
	default destructor

Static Protected Member Functions
static RaveSetup *	getRawInstance ()
	Same as getInstance(), but no check if the instance is initialised.

Protected Attributes
bool	m_useBeamSpot
	flag determines if beam spot information should be used for vertex fit. More...
B2Vector3D	m_beamSpot
	beam spot position. More...
TMatrixDSym	m_beamSpotCov
	beam spot position covariance matrix. More...
rave::VertexFactory *	m_raveVertexFactory
	The RAVE vertex factory is the principal interface offered by the RAVE vertex fitting library.
rave::KinematicTreeFactory *	m_raveKinematicTreeFactory
	< The RAVE Kinematic Tree factory is the principal interface offered by the RAVE for kinematic vertex fitting.
bool	m_initialized
	Has initialize() been called? unusable otherwise.

Member Function Documentation

initialize()

void initialize ( int  verbosity = 1, double  MagneticField = 1.5  )

static

Set everything up so everything needed for vertex fitting is there.

Must be called before RaveVertexFitter can be used

Definition at line 33 of file RaveSetup.cc.

{
  if (getRawInstance()->m_initialized)
    getRawInstance()->reset();
  //now setup everything for the use of GFRave
//  getRawInstance()->m_GFRaveVertexFactory = new GFRaveVertexFactory(verbosity, true);
 
 
  getRawInstance()->m_raveVertexFactory = new rave::VertexFactory(rave::ConstantMagneticField(0, 0, magneticField),
      rave::VacuumPropagator(), "kalman", verbosity);
  getRawInstance()->m_raveKinematicTreeFactory = new rave::KinematicTreeFactory(rave::ConstantMagneticField(0, 0, magneticField),
      rave::VacuumPropagator(), verbosity);
  getRawInstance()->m_initialized = true;
}

reset()

void reset

(

)

frees memory allocated by initialize().

Beam spot is not modified.
