CaloSuperCellUtils.h File Reference

This is a collection of helper functions for building Calo Super Cell detector manager, and for updating it with alignment corrections. The functions previously existed in two packages: CaloDetMgrDetDescrCnv (now obsolete) and CaloDetDescr. They have been moved over to the CaloDetDescrUtils so that now they can also be used by the CaloSuperCellAlignCondAlg. More...
