Heterogeneous tree header only library. Such tree can store node with diffrent data types.

• CMake > 3.16
• Boost > 1.65
• C++17 compatible compiler

1. Clone repository

git clone <url>

2. Enter project directory

cd heterogeneous-tree

3. Run CMake

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=RELEASE

4. Build

cmake --build build

build folder now contains tree_demo executable - demo application for library

Demo application accepts path to file with serialized heterogeneous tree and path to output file, then reads tree from input, prints it to console and saves to output

Program options:

• i,input - path to input file
• o,output - path to output file

samples folder contains example files for demo application:

• sample_input.txt - example of program input
• sample_output.txt - example of program output

1. Define types that tree will store e.g. int, double and std::string
2. Create tree

#include <string>
#include "tree_lib/tree.hpp"

using TreeType = tree_lib::Tree<int, double, std::string>;

TreeType tree;

3. Create nodes and connect them

using TreeNodeType = TreeType::NodeType;

TreeNodeType root = 1;
TreeNodeType leftChild = 2.0;
TreeNodeType rightChild = "str";

root.AddChild(std::move(leftChild));
root.AddChild(std::move(rightChild));

tree.SetRoot(std::move(root));

4. Print tree

#include <iostream>

tree.Print(std::cout);

5. Save and load tree

#include <fstream>

std::ofstream out("..");
tree.Dump(out);

tree.Clear();
std::ifstream in("..");
tree.Load(in);
