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.

Function documentation

Int_t CountMeAndAllDaughters( void )

recursively go through the part of the tree below this node and count all daughters

Bool_t GoesLeft(const TMVA::Event& ) const

 test event if it is equal to the event that "makes the node" (just for the "search tree"

Node* GetLeft()

 return pointer to the left daughter node

{ return fLeft; }

Node* GetRight()

 return pointer to the parent node

{ return fRight; }

void SetLeft(TMVA::Node* l)

 set pointer to the left daughter node

{ fLeft = l;}

void SetRight(TMVA::Node* r)

 set pointer to the parent node

{ fRight = r;}

void SetDepth(UInt_t d)

 Set depth, layer of the where the node is within the tree, seen from the top (root)

{fDepth=d;}

UInt_t GetDepth()

 Return depth, layer of the where the node is within the tree, seen from the top (root)

{return fDepth;}

void SetPos(char s)

 set node position, i.e, the node is a left (l) or right (r) daugther

{fPos=s;}

char GetPos()

 Return the node position, i.e, the node is a left (l) or right (r) daugther

{return fPos;}

TMVA::BinaryTree* GetParentTree()

 Return the pointer to the Parent tree to which the Node belongs

{return fParentTree;}

void SetParentTree(TMVA::BinaryTree* t)

 set the pointer to the Parent Tree to which the Node belongs

{fParentTree = t;}
