/** @brief Joins a list of tokens into a output stream using a delimiter.
36
A list of tokens read from a range is printed to a out stream. The tokens
37
are separated by a token.
39
Example (prints "4, 17, 12"):
41
std::vector<unsigned> v;
45
join(v.begin(), v.end(), ", ", std::cout);
48
template <typename inputIterator, typename separatorType, typename characterType>
49
void join(inputIterator b, inputIterator e, const separatorType& sep, std::basic_ostream<characterType>& out)
52
for (inputIterator it = b; it != e; ++it)
62
/** @brief Joins a list of tokens into a std::string using a delimiter.
64
This function is just like the other join function, but returns the
65
result as a std::string.
67
Example (prints "4, 17, 12"):
69
std::vector<unsigned> v;
73
std::cout << join(v.begin(), v.end(), ", ");
76
template <typename inputIterator, typename separatorType>
77
std::string join(inputIterator b, inputIterator e, const separatorType& sep)
79
std::ostringstream ret;
