28 // Class description:
29 //
30 // Container for all solids, with functionality derived from
31 // std::vector<T>. The class is a 'singleton', in that only
32 // one can exist, and access is provided via the static method
33 // G4SolidStore::GetInstance().
34 //
35 // All solids should be registered with G4SolidStore, and removed on their
36 // destruction. The underlying container initially has a capacity of 100.
37 // A map indexed by solid names is also recorded for fast search;
38 // pointers to solids with same name are stored in buckets.
39 //
40 // If much additional functionality is added, should consider containment
41 // instead of inheritance for std::vector<T>.
