stringstream set delimeter

[Christopher Pisz]

Is there a way to set the delimeter for an istringstream when using the
'>> operator'?

I prefer to not use getline if possible.

You could do it similarly to the example here

Copy-paste of accepted answer from

http://stackoverflow.com/questions/10376199/how-can-i-use-non-default-delimiters-when-reading-a-text-file-with-stdfstream

It looks fine.

#include <locale>
#include <iostream>
#include <algorithm>
#include <iterator>
#include <vector>
#include <sstream>

class my_ctype
: public std::ctype<char>
{
mask my_table[table_size];
public:
my_ctype(size_t refs = 0)
: std::ctype<char>(&my_table[0], false, refs)
{
std::copy_n(classic_table(), table_size, my_table);
my_table['-'] = (mask)space;
my_table['\''] = (mask)space;
}
};

// test
int main()
{
std::istringstream input("This is some input from McDonald's and Burger-King.");
std::locale x(std::locale::classic(), new my_ctype);
input.imbue(x);

std::copy(std::istream_iterator<std::string>(input),
std::istream_iterator<std::string>(),
std::ostream_iterator<std::string>(std::cout, "\n"));

return 0;
}

Output:

This
is
some
input
from
McDonald
s
and
Burger
King.
