31// class G4VPhysicalVolume
32//
33// Class description:
34//
35// This is an Abstract Base class for the representation of positioned volume.
36// The volume is placed within a mother volume, relative to its coordinate
37// system. Either a single positioned volume or many positioned volume can
38// be represented by a particular G4VPhysicalVolume.
39
40// History:
41// 09.11.99 J.Apostolakis Added GetObjectRotationValue() method & redid comments.
42// 28.08.96 P.Kent Replaced transform by rotmat + vector
43// 25.07.96 P.Kent Modified interface for new `Replica' capable geometry
44// 24.07.95 P.Kent First non-stub version
