// Class description:
//
// This is a template class of digi collection and parametrised by
// The concrete class of G4VDigi. This is a uniform collection for
// a particular concrete digi class objects.
// An intermediate layer class G4DigiCollection appeared in this
// header file is used just for G4Allocator, because G4Allocator
// cannot be instantiated with a template class. Thus G4DigiCollection
// class MUST NOT be directly used by the user.
