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