Detailed Description

The basic facility to convert data to a string is the formatter<T> template. It can be accessed by including formatter.hpp in the source code. Its usage is fairly simple, for a scalar type use

#include <iostream>
#include <pni/core/types.hpp>
#include <pni/io/formatter.hpp>

using namespace pni::core;
using namespace pni::io;

typedef pni::io::formatter<float64> float_fmt_type;

int main(int argc,char **argv)
{
    float_fmt_type float_formatter; 
    float64 data=4.3902e+2;

    std::cout<<float_formatter(data)<<std::endl;

    return 0;
}

Also container types can be handled by using the container_io_config type. To convert the data stored in a std::vector to a string use something like this

#include <iostream>
#include <vector>
#include <pni/core/types.hpp>
#include <pni/io/formatter.hpp>

using namespace pni::core;
using namespace pni::io;

typedef std::vector<uint32> mca_type; 
typedef formatter<mca_type> mca_fmt_type; 

int main(int,char **)
{
    mca_fmt_type mca_fmt(container_io_config('[',']',';')); 
    mca_type mca{1,20,84,11};
    container_io_config mca_cfg;

    std::cout<<mca_fmt(mca)<<std::endl;
//    //  will output
//    //  [1;20;84;11]

    return 0;
}
