class TMVA::PDEFoamDensityBase: public TObject


 This is an abstract class, which provides an interface for a
 PDEFoam density estimator.  Derived classes have to implement the
 Density(...) function, which returns the density of a certain
 quantity at a given phase-space point during the foam build-up.

 Variants of PDEFoamDensityBase are:

   - PDEFoamEventDensity
   - PDEFoamDiscriminantDensity
   - PDEFoamTargetDensity
   - PDEFoamDecisionTreeDensity


 The user has to instantiate a child class of PDEFoamDensityBase and
 set the pointer to the owner, which is a PDEFoam object:

   PDEFoamDensityBase *dens = new MyDensity();

 Afterwards the binary search tree should be filled with TMVA
 events, by either using

Function documentation

PDEFoamDensityBase(vector<Double_t> box)
 User constructor

 - box - range-searching box, where box.size() == dimension of
         the PDEFoam == periode of the binary search tree
PDEFoamDensityBase(const TMVA::PDEFoamDensityBase& )
 Copy constructor

 Creates a deep copy, using the copy constructor of
void FillBinarySearchTree(const TMVA::Event* ev)
 This method inserts the given event 'ev' it into the binary
 search tree.
Double_t GetBoxVolume()
 Returns the volume of range searching box fBox.

 If the range searching box 'fBox' has changed (fBoxHasChanged is
 kTRUE), recalculate the box volume and set fBoxHasChanged to
void SetBox(vector<Double_t> box)
 set the range-searching box
{ fBox = box; fBoxHasChanged = kTRUE; }
const std::vector<Double_t>& GetBox() const
 get the range-searching box
{ return fBox; }
Double_t Density(vector<Double_t>& Xarg, Double_t& event_density)
 main function used by PDEFoam
 returns density at a given point by range searching in BST
