// The RefCoreStreamer uses the interface defined here to find the

// EDProductGetter corresponding to the current event and the
7
// ProductID. A pointer to the EDProductGetter is then written into
8
// the RefCore and will get used the first time the Ptr containing the
9
// RefCore is dereferenced. This base class breaks the dependence of
10
// the RefCoreStreamer on the classes that derive from this class. In
11
// the full framework this will be a base class for the
12
// art::EventPrincipal and in gallery this will be a base class for
13
