class TTreeFormulaManager: public TObject

     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.

Function documentation

-*Tree FormulaManger default constructor
*-*                  ======================================
-*Tree FormulaManager default destructor
*-*                  ======================================
void Remove(TTreeFormula* )
 Remove a formula from this manager
void Add(TTreeFormula* )
 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 = kFALSE)
-*-*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() const
{return fMultiplicity;}
Bool_t Notify()
{ UpdateFormulaLeaves(); return kTRUE; }
