Function documentation

TLeaf(TBranch* parent, const char* name, const char* type)
 Create a Leaf.

 See the TTree and TBranch constructors for explanation of parameters.
TLeaf(const TLeaf& )
copy constructor
TLeaf& operator=(const TLeaf& )
assignment operator
 -- Destructor.
void Browse(TBrowser* b)
 Browse the content of this leaf.
void FillBasket(TBuffer& b)
 -- Pack leaf elements in Basket output buffer.
TLeaf* GetLeafCounter(Int_t& countval) const
 -- Return a pointer to the counter of this leaf.

  If leaf name has the form var[nelem], where nelem is alphanumeric, then
     if nelem is a leaf name, return countval = 1 and the pointer to
          the leaf named nelem, otherwise return 0.
  If leaf name has the form var[nelem], where nelem is a non-negative integer, then
     return countval = nelem and a null pointer.
  If leaf name has the form of a multi-dimensional array (e.g. var[nelem][nelem2]
     where nelem and nelem2 are non-negative integers) then
     return countval = product of all dimension sizes and a null pointer.
  If leaf name has the form var[... (and does not match the previous 2
     cases) return countval = -1 and null pointer;
  Otherwise return countval = 1 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 = kFALSE)
 -- Helper routine for TLeafX::SetAddress.

 The return value is non-zero if we owned the old
 value buffer and must delete it now.  The size
 of the value buffer is recalculated and stored,
 and a decision is made whether or not we own the
 new value buffer.

void SetLeafCount(TLeaf* leaf)
 -- Set the leaf count of this leaf.
void Streamer(TBuffer& )
 -- Stream a class object.
