node. It is used internally in classification trees and tree ensembles.

int cv::ml::DTrees::Node::defaultDir

 Default direction where to go (-1: left or +1: right). It helps in the

case of missing values.

int cv::ml::DTrees::Node::left

Index of the left child node.

int cv::ml::DTrees::Node::parent

Index of the parent node.

int cv::ml::DTrees::Node::right

Index of right child node.

int cv::ml::DTrees::Node::split

Index of the first split.

double cv::ml::DTrees::Node::value

 Value at the node: a class label in case of classification or estimated

function value in case of regression.
