ccntreenode

Welcome to the documentation for the ccntreenode framework. This framework provides a reliable and efficient way to work with trees in your iOS or macOS applications. Whether you are building a navigation menu, a file system structure, or any other hierarchical data, ccntreenode is designed to simplify the implementation process.

Installation

To install ccntreenode in your project, you have several options:

  1. Using CocoaPods:

    2. pod 'ccntreenode'

  2. Manual installation:
    • Download the latest release from the GitHub repository.
    • Add the ccntreenode files to your Xcode project.

Usage

Creating a Tree

To create a tree, start by importing the ccntreenode framework:

import ccntreenode

Then, create a new instance of a TreeNode:

let rootNode = TreeNode(value: "Root")

You can add child nodes to the root node:

rootNode.addChild(TreeNode(value: "Child 1"))
rootNode.addChild(TreeNode(value: "Child 2"))
rootNode.addChild(TreeNode(value: "Child 3"))

Traversing the Tree

To traverse the tree and access its nodes, you can use various methods:

  • parentNode.children – returns an array of child nodes for a given parent node.
  • treeNode.parent – returns the parent node of a given node.
  • treeNode.depth – returns the depth of a node within the tree.
  • treeNode.isLeaf – returns a boolean value indicating whether a node is a leaf node.

Updating and Modifying the Tree

You can update and modify the tree in various ways:

  • treeNode.addChild(newChild) – adds a child node to a given parent node.
  • treeNode.remove() – removes a node from the tree.
  • treeNode.updateValue(newValue) – updates the value of a node.

Examples

Example 1: Creating a tree and accessing child nodes

// Create a root node
let rootNode = TreeNode(value: "Root")

// Add child nodes
rootNode.addChild(TreeNode(value: "Child 1"))
rootNode.addChild(TreeNode(value: "Child 2"))
rootNode.addChild(TreeNode(value: "Child 3"))

// Accessing child nodes
let childNodes = rootNode.children
for childNode in childNodes {
print(childNode.value)
}

Example 2: Updating the tree

// Updating a node's value
let rootNode = TreeNode(value: "Root")
let childNode = TreeNode(value: "Child")
rootNode.addChild(childNode)

childNode.updateValue("Modified Child")
print(childNode.value)

// Removing a node
childNode.remove()

// Checking the tree's structure
let isTreeEmpty = rootNode.isLeaf

Conclusion

The ccntreenode framework provides a straightforward approach to working with trees in iOS and macOS applications. Whether you are creating complex hierarchical structures or simple navigation menus, ccntreenode simplifies the process and allows for efficient management of tree data.
