Detailed Description

A holder for all the Geant4 field related objects.

These are the objects that are required for a magnetic field other than the magnetic field itself. If owns all objects apart from the G4MagneticField. This is used purely to construct the other objects or as a reference to which field they're based on.

Constructor & Destructor Documentation

◆ BDSFieldObjects() [1/4]

BDSFieldObjects::BDSFieldObjects ( const BDSFieldObjects & other )

delete

Avoid shallow pointer copy and possible double deletion. Could possibly implement this with the info and the field factory.

◆ BDSFieldObjects() [2/4]

BDSFieldObjects::BDSFieldObjects	(	const BDSFieldInfo *	infoIn,
		G4Field *	fieldIn,
		G4EquationOfMotion *	equationOfMotionIn,
		G4MagIntegratorStepper *	magIntegratorStepperIn,
		G4ChordFinder *	chordFinderIn,
		G4FieldManager *	fieldManagerIn
	)

A field is required to build the required objects to manage and use it.

Definition at line 36 of file BDSFieldObjects.cc.

◆ BDSFieldObjects() [3/4]

BDSFieldObjects::BDSFieldObjects	(	const BDSFieldInfo *	infoIn,
		G4ElectroMagneticField *	fieldIn,
		G4EquationOfMotion *	equationOfMotionIn,
		G4MagIntegratorStepper *	magIntegratorStepperIn
	)

Alternative constructor for the special case of an electro-magnetic field which doesn't follow the same hierarchy of classes as magnetic fields. This can also be used for a second argument of G4MagneticField as this inherits G4ElectroMagneticField.

◆ BDSFieldObjects() [4/4]

BDSFieldObjects::BDSFieldObjects	(	const BDSFieldInfo *	infoIn,
		G4MagneticField *	fieldIn,
		G4EquationOfMotion *	equationOfMotionIn,
		G4MagIntegratorStepper *	magIntegratorStepperIn
	)

In Geant4.10.5.b01, the field class inheritance has changed and G4MagneticField no longer inherits G4ElectroMagneticField.

◆ ~BDSFieldObjects()

BDSFieldObjects::~BDSFieldObjects ( )

Destructor deletes all objects apart from the magnetic field.

◆ AttachToVolume() [1/2]

void BDSFieldObjects::AttachToVolume	(	const std::vector< G4LogicalVolume * > &	volumes,
		G4bool	penetrateToDaughterVolumes = `true`
	)		const

Interface to easily attach to logical volumes.

◆ AttachToVolume() [2/2]

void BDSFieldObjects::AttachToVolume	(	G4LogicalVolume *	volume,
		G4bool	penetrateToDaughterVolumes = `true`
	)		const

Interface to easily attach to logical volume.

Here is the caller graph for this function:

◆ AttachUserLimitsToVolume()

void BDSFieldObjects::AttachUserLimitsToVolume	(	G4LogicalVolume *	volume,
		G4UserLimits *	userLimits,
		G4bool	penetrateToDaughterVolumes = `true`
	)		const

Attach user limits to a volume and optionally recurse to daughters. Note this will override any existing G4UserLimits on the volume or daughters. We rely on BDSFieldInfo::defaultUL coming from BDSGlobalConstants which will pick up kinetic energy limits.
