class RooRefCountList: public RooLinkedList

A RooRefCountList is a RooLinkedList that keeps a reference counter with each added node. Multiple Add()s of the same object will increase the counter instead of adding multiple copies. Remove() decrements the reference count until zero, when the object is actually removed.

Function documentation

RooRefCountList()

 Default constructor construct lists with initial hash table size of 17

void Add(TObject* obj, Int_t count)

 Add object to list with given reference count increment
 List takes ownership of object.

Bool_t Remove(TObject* obj)

 Remove object from list and if reference count
 reaches zero delete object itself as well.

Bool_t RemoveAll(TObject* obj)

 Remove object from list and delete object itself
 regardless of reference count

Int_t refCount(TObject* obj)

 Return reference count associated with 'obj'

RooRefCountList()

virtual ~RooRefCountList()

{}

void Add(TObject* arg)

{ Add(arg,1) ; }
