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)
