Member Enumeration Documentation

EGeoComponent

enum o2::fv0::Geometry::EGeoComponent

Geometry components possible to be enabled/disabled. Only enabled components will be created.

Enumerator
eScintillator
ePlastics
ePmts
eFibers
eScrews
eRods
eContainer

Definition at line 67 of file Geometry.h.

EGeoType

enum o2::fv0::Geometry::EGeoType

Geometry type options possible to be initialized. The type of the geometry will specify which components are created. Geometry types -> eUnitialized => no parts -> eOnlySensitive => only sensitive detector parts -> eRough => sensitive parts and rough structural elements -> eFull => complete, detailed geometry (including screws, etc.)

Enumerator
eUninitialized
eOnlySensitive
eRough
eFull

Constructor & Destructor Documentation

Geometry() [1/2]

o2::fv0::Geometry::Geometry ( )

inline

Default constructor. It must be kept public for root persistency purposes, but should never be called by the outside world

Definition at line 80 of file Geometry.h.

Geometry() [2/2]

Geometry::Geometry

(

const Geometry &

geometry

)

Copy constructor.

Definition at line 46 of file Geometry.cxx.

~Geometry()

Geometry::~Geometry

(

)

Definition at line 51 of file Geometry.cxx.

Member Function Documentation

buildGeometry()

void Geometry::buildGeometry

(

)

const

Build the geometry.

Definition at line 95 of file Geometry.cxx.

enableComponent()

bool Geometry::enableComponent	(	EGeoComponent	component,
		bool	enable = true
	)

Enable or disable a geometry component. To be called before the geometry is built. A disabled component will not be added to the geometry. The enabled components are by default specified by the geometry type.

Parameters

component	The geometry component to be enabled/disabled.
enable	Setting the enabled state. Default is true.

Returns

The enabled state of the geometry component.

Definition at line 85 of file Geometry.cxx.

getCellCenter()

Point3Dsimple & Geometry::getCellCenter

(

UInt_t

cellId

)

Definition at line 125 of file Geometry.cxx.

getCurrentCellId()

int Geometry::getCurrentCellId

(

const TVirtualMC *

fMC

)

const

Get the unique ID of the current scintillator cell during simulation. The ID is a number starting from 0 at the first cell right of the y-axis and continues clockwise one ring at a time.

Parameters

fMC	The virtual Monte Carlo interface.

Returns

The ID of the current scintillator cell during simulation.

Definition at line 61 of file Geometry.cxx.

inlinestatic

Definition at line 136 of file Geometry.h.

getDetID()

static constexpr o2::detectors::DetID::ID o2::fv0::Geometry::getDetID ( )

inlinestaticconstexpr

Definition at line 128 of file Geometry.h.

getGlobalPosition()

void Geometry::getGlobalPosition	(	float &	x,
		float &	y,
		float &	z
	)

Utility functions to be accessed externally.

Sets the input parameters to the position of the geometrical center of sensitive detector

Parameters

x	x [cm].
y	y [cm].
z	z [cm].

Definition at line 118 of file Geometry.cxx.

inlinestaticconstexpr

Definition at line 121 of file Geometry.h.

getPmtDensity()

static constexpr float o2::fv0::Geometry::getPmtDensity ( )

inlinestaticconstexpr

Get the density of the PMTs.

Definition at line 147 of file Geometry.h.

getPNEntry()

TGeoPNEntry * o2::fv0::Geometry::getPNEntry ( int  index ) const

inline

Get a pointer to the TGeoPNEntry of a chip identified by 'index' Returns NULL in case of invalid index, missing TGeoManager or invalid symbolic name

Definition at line 129 of file Geometry.h.

getReadoutCenter()

Point3Dsimple & Geometry::getReadoutCenter

(

UInt_t

cellId

)

Definition at line 130 of file Geometry.cxx.

getSensitiveVolumeNames()

const std::vector< std::string > & o2::fv0::Geometry::getSensitiveVolumeNames ( ) const

inline

Get the names of all the sensitive volumes of the geometry.

Returns

The names of all the sensitive volumes of the geometry.

Definition at line 100 of file Geometry.h.

instance()

Geometry * Geometry::instance ( EGeoType  initType = eUninitialized )

static

Access to geometry instance

Parameters

initType

The geometry type to be initialized - if the geometry already exists this parameter is ignored

Definition at line 1346 of file Geometry.cxx.

isRing5()

bool Geometry::isRing5

(

UInt_t

cellId

)

Helper function to check if the cellId belongs to ring 5.

Parameters

cellId
