std::vector< int >	getElementLabels (DetectorLevelElement element) override
	Rigid body labels.
template<class LowestLevelDBObject >
GlobalDerivativeSet	getGlobalDerivatives (unsigned short sensor, const genfit::StateOnPlane *sop)
	Get globals for given db object (and the rest of hierarchy) and its element at StateOnPlane.

	Insert hierarchy relation.

	Insert hierarchy relation.

	Conversion from G4Transform3D to 6D rigid body transformation parametrization.
TMatrixD	convertTGeoToRigidBodyTransformation (TGeoHMatrix tgeo)
	Conversion from G4Transform3D to 6D rigid body transformation parametrization.
void	buildConstraints (Constraints &constraints)
	Adds constraints from current hierarchy to a constraints vector.
GlobalDerivativeSet	buildGlobalDerivativesHierarchy (TMatrixD matrixChain, DetectorLevelElement child)
	Recursive function which adds labels and derivatives until top element in hierarchy is found.
template<class ChildDBObjectType , class MotherDBObjectType >
void	insert (unsigned short child, unsigned short mother, TMatrixD childToMotherParamTransform)
	Template function to add relation between two elements (possibly in different objects with constants) First object is the child object, second its hierarchy parent. More...
void	printHierarchy ()
	print the lookup map
const std::set< unsigned short > &	getUsedDBObjUniqueIDs ()
	Get the global unique ids of DB objects used to construct hierarchy Usefull to update hierarchy only when those changed.

Static Public Member Functions
static void	mergeGlobals (GlobalDerivativeSet &main, GlobalDerivativeSet additional)
	Merge additional set into main set of global labels and derivatives TODO: move to some utilities.

Private Member Functions
std::pair< DetectorLevelElement, TMatrixD >	getChildToMotherTransform (DetectorLevelElement child)
	Find the transformation in the lookup.

Private Attributes
std::map< DetectorLevelElement, std::pair< DetectorLevelElement, TMatrixD > >	m_lookup
	Map with all the parameter data (child -> (mother, transform_child2mother))
std::map< DetectorLevelElement, std::vector< DetectorLevelElement > >	m_hierarchy
	Map of hierarchy relations mother-> child.
std::set< unsigned short >	m_usedUniqueIDs {}
	The set of unique id of each DB object used for construction For more efficient updates of hierarchy only when used objects change.

Member Function Documentation

insert()

void insert ( unsigned short  child, unsigned short  mother, TMatrixD  childToMotherParamTransform  )

inlineinherited

Template function to add relation between two elements (possibly in different objects with constants) First object is the child object, second its hierarchy parent.

Parameters

child	is the lement numeric id in child obj
mother	is the parent object
childToMotherParamTransform	is the transformation matrix (placement from geometry of the detector)
