ROOT 6.10/09 Reference Guide |
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.
