Constructor & Destructor Documentation

Ex03dCalorimeterSD() [1/3]

Ex03dCalorimeterSD::Ex03dCalorimeterSD	(	const char *	name,
		Ex03DetectorConstruction *	detector )

Standard constructor. Create hits collection and an empty hit for each layer As the copy numbers may start from 0 or 1 (depending on geometry model, we create one more layer for this case.)

Parameters

name	The calorimeter hits collection name
detector	The detector construction

Definition at line 37 of file Ex03dCalorimeterSD.cxx.
