fcppt::homogenous_pair< T > Class Template Reference

Detailed Description

template<typename T>
class fcppt::homogenous_pair< T >

A pair like std::pair with both elements of the same type.

A homogenous pair of type T is like an std::pair<T,T>. A short example:

#include <fcppt/homogenous_pair.hpp>
#include <fcppt/text.hpp>
#include <fcppt/io/cout.hpp>


int main()
{

        typedef fcppt::homogenous_pair<
                int
        > int_pair;

        int_pair test1(
                5,
                10
        );

        test1.first = 42;

        fcppt::io::cout()
                << test1
                << FCPPT_TEXT('\n');
}
