|
// Class description:
|
|
//
|
|
// Container for all assemblies, with functionality derived from
|
|
// std::vector<T>. The class is a `singleton', in that only
|
|
// one can exist, and access is provided via the static method
|
|
// G4AssemblyStore::GetInstance().
|
|
//
|
|
// All assemblies should be registered with G4AssemblyStore, and removed on
|
|
// their destruction. The underlying container initially has a capacity of 20.
|
|
//
|
|
// If much additional functionality is added, should consider containment
|
|
// instead of inheritance for std::vector<T>.
