Constructor & Destructor Documentation

DTLayerId::DTLayerId

(

)

Default constructor. Fills the common part in the base and leaves 0 in all other fields

DTLayerId::DTLayerId ( uint32_t  id )

explicit

Construct from a packed id. It is required that the packed id represents a valid DT DetId (proper Detector and SubDet fields), otherwise an exception is thrown. Any bits outside the DTLayerId fields are zeroed; apart for this, no check is done on the vaildity of the values.

DTLayerId::DTLayerId	(	int	wheel,

Construct from indexes. Input values are required to be within legal ranges, otherwise an exception is thrown.
