std::experimental::make_ostream_joiner

Defined in header <experimental/iterator>
template< class CharT, class Traits, class DelimT >

std::experimental::ostream_joiner<std::decay_t<DelimT>, CharT, Traits>
    make_ostream_joiner( std::basic_ostream<CharT, Traits>& os,

                         DelimT&& delimiter );
 (library fundamentals TS v2)

Creates an ostream_joiner object, deducing the template arguments from the types of the function arguments.

Parameters

os - the basic_ostream object that the iterator is to be associated to
delimiter - the delimiter

Return value

An ostream_joiner object, created as if by std::experimental::ostream_joiner<std::decay_t<DelimT>, CharT, Traits>(os, std::forward<DelimT>(delimiter))

Example

#include <experimental/iterator>
#include <iostream>
#include <vector>
 
int main()
{
    std::vector<int> x{1, 2, 3, 4};
    std::copy(x.begin(), x.end(),
              std::experimental::make_ostream_joiner(std::cout, ", "));
}

Output:

1, 2, 3, 4
