// class G4LogicalVolumeStore
//
// Class description:
//
// Container for all LogicalVolumes, 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 function
// G4LogicalVolumeStore::GetInstance()
//
// All LogicalVolumes should be registered with G4LogicalVolumeStore,
// and removed on their destruction. Intended principally for UI browser.
// The underlying container initially has a capacity of 100.
//
// If much additional functionality is added, should consider containment
// instead of inheritance for std::vector<T>.
//
// Member data:
//
// static G4LogicalVolumeStore* fgInstance
//   - Ptr to the single G4LogicalVolumeStore.

// History:
// 18.04.01 G.Cosmo Migrated to STL vector
// 10.07.95 P.Kent  Initial version
// --------------------------------------------------------------------
