template<class T>
class RooSTLRefCountList< T >

The RooSTLRefCountList is a simple collection of pointers to the template objects with reference counters.

The pointees are not owned, hence not deleted when removed from the collection. Objects can be searched for either by pointer or by name (confusion possible when objects with same name are present). This replicates the behaviour of the RooRefCountList.
