Provided methods

pub fn value(&self) -> f64[src]

Value at the node: a class label in case of classification or estimated function value in case of regression.

pub fn set_value(&mut self, val: f64)[src]

Value at the node: a class label in case of classification or estimated function value in case of regression.

pub fn class_idx(&self) -> i32[src]

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

pub fn set_class_idx(&mut self, val: i32)[src]

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

pub fn parent(&self) -> i32[src]

Index of the parent node

pub fn set_parent(&mut self, val: i32)[src]

Index of the parent node

pub fn left(&self) -> i32[src]

Index of the left child node

pub fn set_left(&mut self, val: i32)[src]

Index of the left child node

pub fn right(&self) -> i32[src]

Index of right child node

pub fn set_right(&mut self, val: i32)[src]

Index of right child node

pub fn default_dir(&self) -> i32[src]

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

pub fn set_default_dir(&mut self, val: i32)[src]

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

pub fn split(&self) -> i32[src]

Index of the first split

pub fn set_split(&mut self, val: i32)[src]

Index of the first split
