Function documentation

TLeaf(const TLeaf& )
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& )
assignement operator
~TLeaf()
 -- 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.
  If leaf name has the form 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()
 -- 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& b)
 -- Stream a class object.
