31 // Class Description:
32 // G4Mesh encapsulates and validates a nested parameterisation, which we
33 // call a "mesh". If a valid mesh cannot be created out of this
34 // G4VPhysicalVolume* (which will probably be most common), it will
35 // have a type "invalid". Then, usually, it may simply be destroyed.
36 // The overhead of an invalid attempt is expected to be small.
