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

TTreeFormulaManager()

-*Tree FormulaManger default constructor
*-*                  ======================================

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; }
