Variant CPP

-----------

A flexible C++ data structure, which can contain any type

Just for fun. But I will continue to improve it. :P

*Note: This library is written in C++11 standard*

Usage

=====

.. code:: cpp

    #include "VariantList.hpp"

    #include 

    #include 

    using namespace std;

    int main(int argc, char *argv[]) {

        VariantList variant_list;

        variant_list.push_back(1); // int

        variant_list.push_back(1.2); // double

        variant_list.push_back("Hello"); // string

        VariantList another_list;

        another_list.push_back(10);

        another_list.push_back(10.1f);

        variant_list.push_back(another_list); // !!

        variant_list.push_back(variant_list); // !!

        cout << variant_list << endl;

        auto itr = variant_list.begin();

        cout << "First: " << itr->get() << endl;

        ++ itr;

        cout << "Second: " << itr->get() << endl;

        ++ itr;

        cout << "Third: " << itr->get() << endl;

        *itr = make_variant(10.2); // Change element 3 "Hello" (std::string) to 10.2 (Double)

        cout << "Third: " << itr->get() << endl;

        cout << variant_list << endl;

        return 0;

    }

Run the previous code section will print

.. code::

    [1, 1.2, Hello, [10, 10.1], [1, 1.2, Hello, [10, 10.1]]]

    First: 1

    Second: 1.2

    Third: Hello

    Third: 10.2

    [1, 1.2, 10.2, [10, 10.1], [1, 1.2, Hello, [10, 10.1]]]

TODO

====

* Improve usability

* Implement other kind of variant data structure
