Class Description


     A TreeFormulaManager is used to coordinate one or more TTreeFormula objecs

  In particular it makes sure that the dimensions and size of all the formulas
  is properly coordinated.
TTreeFormulaManager()
*-*-*-*-*-*-*-*-*-*-*Tree FormulaManger default constructor*-*-*-*-*-*-*-*-*-*
*-*                  ======================================
~TTreeFormulaManager()
*-*-*-*-*-*-*-*-*-*-*Tree FormulaManager default destructor*-*-*-*-*-*-*-*-*-*
*-*                  ======================================
void Remove(TTreeFormula* adding)
 Remove a formula from this manager
void Add(TTreeFormula* adding)
 Add a new formula to the list of formulas managed
 The manager of the formula will be changed and the old one will be deleted
 if it is empty.
void AddVarDims(Int_t virt_dim)
 Add a variable dimension
void CancelDimension(Int_t virt_dim)
 Cancel a dimension.  This is usually called when an out-of-bounds index
 is used.
void EnableMultiVarDims()
 Set the manager as handling a formula with multiple variable dimensions
Int_t GetNdata(Bool_t forceLoadDim)
*-*-*-*-*-*-*-*Return number of available instances in the formulas*-*-*-*-*-*
*-*            ====================================================
Bool_t Sync()
 Synchronize all the formulae.
void UpdateFormulaLeaves()
 this function could be called TTreePlayer::UpdateFormulaLeaves, itself
 called by TChain::LoadTree when a new Tree is loaded.
 Because Trees in a TChain may have a different list of leaves, one
 must update the leaves numbers in the TTreeFormula used by the TreePlayer.
void UpdateUsedSize(Int_t &virt_dim, Int_t vsize)
 Reload the array sizes
TTreeFormulaManager(const TTreeFormulaManager&)
 Not implemented yet
TTreeFormulaManager& operator=(const TTreeFormulaManager&)
Int_t GetMultiplicity()
{return fMultiplicity;}
Bool_t Notify()
{ UpdateFormulaLeaves(); return kTRUE; }
