class TMVA::Node


  Node for the BinarySearch or Decision Trees.

  For the binary search tree, it basically consists of the EVENT, and
  pointers to the parent and daughters

  In case of the Decision Tree, it specifies parent and daughters, as
  well as "which variable is used" in the selection of this node,
  including the respective cut value.

Node()
 default constructor
Node(TMVA::Node* p, char pos)
 constructor of a daughter node as a daughter of 'p'
Node(const TMVA::Node& n)
 copy constructor, make sure you don't just copy the poiter to the node, but
 that the parents/daugthers are initialized to 0 (and set by the copy
 constructors of the derived classes
~Node()
 node destructor
int GetCount()
 retuns the global number of instantiated nodes
Int_t CountMeAndAllDaughters() const
recursively go through the part of the tree below this node and count all daughters
void* AddXMLTo(void* parent) const
 add attributes to XML
void ReadXML(void* node, UInt_t tmva_Version_Code = 262657)
 read attributes from XML
Node* CreateNode() const
Bool_t GoesRight(const TMVA::Event& ) const
 test event if i{ decends the tree at this node to the right
Bool_t GoesLeft(const TMVA::Event& ) const
 test event if it decends the tree at this node to the left
Node* GetLeft() const
 test event if it is equal to the event that "makes the node" (just for the "search tree"
 return pointer to the left/right daughter or parent node
{ return fLeft; }
Node* GetRight() const
