st_tree: A fast and flexible c++ template class for tree data structures

Build Status

Introduction

The st_tree library implements a C++ template tree container class for storing data in arbitrary tree structures. st_tree is short for “standard template tree,” and supports STL-compatible interfaces including iterators, allocators and standard STL container methods.

The st_tree library allows the programmer to easily declare and manipulate data in a tree:

// declare a tree of integers, where children are stored using a vector storage model
tree<int> t1;  

// declare a tree of strings, where node children are maintained in sorted order
tree<string, ordered<> > t2;

// declare a tree of floating point, where children are indexed by a string label
tree<float, keyed<string> > t3;

Features

The st_tree template container class provides the following features

Install

The st_tree project home is here: https://github.com/erikerlandson/st_tree

Instructions for download and install are here: https://github.com/erikerlandson/st_tree/wiki/st_tree-installation-and-building

Quick start:

# generate makefiles from cmake
$ cd /path/to/st_tree
$ cmake .

# generate makefiles to build examples from cmake
$ cd /path/to/st_tree
$ cmake . -DBUILD_EXAMPLES=ON

# make examples and tests:
$ make

# run unit tests
$ ./tests/unit_tests

# installs header files and cmake integrations to /usr/local
$ make install

To build st_tree with a particular c++ standard (e.g. c++ 11, 14, 17, etc):

$ cmake -D CMAKE_CXX_STANDARD=14 .
