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(const TTreeFormulaManager& )
-*Tree FormulaManger default constructor
*-*                  ======================================
~TTreeFormulaManager()
-*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()
{return fMultiplicity;}
Bool_t Notify()
{ UpdateFormulaLeaves(); return kTRUE; }
