Public Types

typedef std::pair< G4LogicalVolume *, G4Transform3D > Placement
 Placement of a logical volume consists of the Volume and ins transformation.
 

Public Member Functions

void place (G4LogicalVolume *mother, const G4Transform3D &transform)
 Place all the volumes already added to the assembly in the given mother.
 
void add (G4LogicalVolume *volume, const G4Transform3D &transform=G4Transform3D())
 Add a volume to the assembly.
 
void add (const GeoVXDAssembly &assembly, const G4Transform3D &transform=G4Transform3D())
 Add a assembly to the assembly.
 

Private Attributes

std::vector< Placement > m_volumes
 Array of all volumes and their placements in the assembly.
 

Detailed Description

Class to group some Geant4 volumes and place them all at once with a given transformation matrix.

This is similar to the G4VolumeAssembly but is much simpler and with less options
