## Detailed Description

The class represents a decision tree node.

## Constructor & Destructor Documentation

## § Node()

cv::ml::DTrees::Node::Node | ( |  | ) |

## Member Data Documentation

## § classIdx

int cv::ml::DTrees::Node::classIdx

Class index normalized to 0..class_count-1 range and assigned to the node. It is used internally in classification trees and tree ensembles.

## § defaultDir

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

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

## § left

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

Index of the left child node.

## § parent

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

Index of the parent node.

## § right

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

Index of right child node.

## § split

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

Index of the first split.

## § value

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.
