0027 //
0028 // Class description:
0029 //
0030 // Container for all solids, with functionality derived from
0031 // std::vector<T>. The class is a 'singleton', in that only
0032 // one can exist, and access is provided via the static method
0033 // G4SolidStore::GetInstance().
0034 //
0035 // All solids should be registered with G4SolidStore, and removed on their
0036 // destruction. The underlying container initially has a capacity of 100.
0037 // A map indexed by solid names is also recorded for fast search;
0038 // pointers to solids with same name are stored in buckets.
0039 //
0040 // If much additional functionality is added, should consider containment
0041 // instead of inheritance for std::vector<T>.
