MEOS C++ example

This project shows a minimal example for how MEOS can be used in C++ projects.

Code Snippet

#include <iostream>
#include <meos/types/temporal/TSequence.hpp>
#include "time_utils.cpp"

using namespace std;
using namespace meos;


int main() {
    set<TInstant<int>> instants = {
        TInstant<int>(2, unix_time_point(2012, 1, 1)),
        TInstant<int>(1, unix_time_point(2012, 1, 2)),
        TInstant<int>(4, unix_time_point(2012, 1, 3)),
        TInstant<int>(3, unix_time_point(2012, 1, 4)),
    };
    TSequence<int> tseq(instants);
    cout << tseq << endl;
    return 0;
}

Building

cmake -B build -S .
cmake --build build

Note: It is assumed you have libgeos-dev installed on your system.

Running

./build/app

If you see the following output, you have succesfully ran the example application! :)

[2@2012-01-01T00:00:00+0000, 1@2012-01-02T00:00:00+0000, 4@2012-01-03T00:00:00+0000, 3@2012-01-04T00:00:00+0000)

How it works

In CMakeLists.txt file you can see that MEOS is included and linked using CPM

include(cmake/CPM.cmake)

CPMAddPackage(
  NAME MEOS
  GITHUB_REPOSITORY adonmo/meos
  GIT_TAG 0.1
)

When you run cmake build, specified version of the library is fetched and linked to the application

Of course, you can build much more useful and all sorts of complex applications using MEOS. Here are some links to help you out:
