RooFIter fwdIterator() const
Create a one-time-use forward iterator for this list.
A RooRefCountList is a RooLinkedList that keeps a reference counter with each added node.
Int_t refCount(TObject *obj) const
Return reference count associated with 'obj'.
void Add(T *obj, std::size_t initialCount=1)
Add an object or increase refCount if it is already present.

RooSTLRefCountList< RooAbsArg > convert(const RooRefCountList &old)
Converter from the old RooRefCountList to RooSTLRefCountList.
The namespace RooFit contains mostly switches that change the behaviour of functions of PDFs (or othe...
