30 //
31 // Class description:
32 //
33 // Container for all FieldManagers, with functionality derived from
34 // std::vector<T>. The class is a `singleton', in that only
35 // one can exist, and access is provided via the static function
36 // G4FieldManagerStore::GetInstance()
37 //
38 // All FieldManagers should be registered with G4FieldManagerStore,
39 // and removed on their destruction.
40 // Intended principally to enable resetting of 'state' at start of event.
41 // The underlying container initially has a capacity of 100.
42 //
43 // Member data:
44 //
45 // static G4FieldManagerStore* fgInstance
46 // - Ptr to the single G4FieldManagerStore.
