class	G4Volume
	Convenience container holding a Geant4 solid, logical, and physical volume. More...

Detailed Description

g4system factories progressively build Geant4 geometry in three stages:

1. create a G4VSolid
2. wrap it into a G4LogicalVolume (material + visualization)
3. place it into the geometry tree as a G4VPhysicalVolume

This class caches the three pointers so that different build steps can share the same already-created objects without having to re-query Geant4 stores.

Note

This wrapper does not own any Geant4 object. Pointer lifetimes are managed by Geant4 stores and by the code that registers volumes into those stores.
