ROOT 6.14/05 Reference Guide |
RooLinkedList is an collection class for internal use, storing a collection of RooAbsArg pointers in a doubly linked list.
It can optionally add a hash table to speed up random access in large collections Use RooAbsCollection derived objects for public use (e.g. RooArgSet or RooArgList)

Make a clone of an object using the Streamer facility.
If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.
If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.
