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...

inlinestatic

get the pointer to the instance to get/set any of options stored in RaveSetup

Definition at line 43 of file RaveSetup.h.

        RaveSetup* instance = getRawInstance();
        if (!instance->m_initialized) {

getRawInstance()

RaveSetup * getRawInstance ( )

staticprotected

Same as getInstance(), but no check if the instance is initialised.

Definition at line 29 of file RaveSetup.cc.

{
  static RaveSetup instance;
  return &instance;
}

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 35 of file RaveSetup.cc.

{
  if (getRawInstance()->m_initialized)
    getRawInstance()->reset();
  //now setup everything for the use of GFRave

}

Print()

void Print ( )

static

Print() writes all RaveSetup member variables to the terminal.

Definition at line 89 of file RaveSetup.cc.

    if (getRawInstance()->m_useBeamSpot == false) {
      B2INFO("use beam spot is false");

  } else {
    B2INFO("RaveSetup::initialize was not called. There is nothing to Print.");
  }
}

reset()

void reset

(

)

frees memory allocated by initialize().

Beam spot is not modified.

Definition at line 60 of file RaveSetup.cc.

setBeamSpot()

void setBeamSpot	(	const ROOT::Math::XYZVector &	beamSpot,
