Detailed Description

Single entry point to the tracker and muon geometries. The main purpose is to provide the methods idToDetUnit(DetId) and idToDet(DetId) that allow to get an element of the geometry given its DetId, regardless of wich subdetector it belongs.

The slave geometries (TrackerGeometry, DTGeometry, CSCGeometry, RPCGeometry) are accessible with the method slaveGeometry(DetId).
