Class Description

 A TLeaf describes individual elements of a TBranch                   
       See TBranch structure in TTree.                                

TLeaf(): TNamed()
*-*-*-*-*-*Default constructor for Leaf*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*        ============================

TLeaf(const char *name, const char *) :TNamed(name,name)
*-*-*-*-*-*-*-*-*-*-*-*-*Create a Leaf*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      =============

     See the TTree and TBranch constructors for explanation of parameters.

*-*-*-*-*-*Default destructor for a Leaf*-*-*-*-*-*-*-*-*-*-*-*
*-*        ===============================

void Browse(TBrowser *b)

void FillBasket(TBuffer &)
*-*-*-*-*-*-*-*-*-*-*Pack leaf elements in Basket output buffer*-*-*-*-*-*-*
*-*                  =========================================

TLeaf* GetLeafCounter(Int_t &countval) const
*-*-*-*-*-*-*Return Pointer to counter of referenced Leaf*-*-*-*-*-*-*-*
*-*          ============================================

  If leaf name has the forme var[nelem], where nelem is alphanumeric, then
     If nelem is a leaf name, return countval = 1 and the pointer to
     the leaf named nelem.
  If leaf name has the forme var[nelem], where nelem is a digit, then
     return countval = nelem and a null pointer.
  Otherwise return countval=0 and a null pointer.

Int_t GetLen() const
*-*-*-*-*-*-*-*-*Return the number of effective elements of this leaf*-*-*-*
*-*              ====================================================

Int_t ResetAddress(void *add, Bool_t destructor)
*-*-*-*-*-*-*-*-*-*-*Set leaf buffer data address*-*-*-*-*-*
*-*                  ============================

  This function is called by all TLeafX::SetAddress

void SetLeafCount(TLeaf *leaf)

void Streamer(TBuffer &b)
*-*-*-*-*-*-*-*-*Stream a class object*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*              =========================================
