# NSTreeNode

A node in a tree of nodes.

## Declaration

```swift
class NSTreeNode
```

## Overview

Overview NSTreeNode simplifies the creation and management of trees of objects. Each tree node represents a model object. A tree node with nil as its parent node is considered the root of the tree.

## Topics
