I would like to split a string along whitespaces, and I know that the tokens represent valid integers. I would like to transform the tokens into integers and populate a vector with them.
I could use boost::split, make a vector of token strings, then use std::transform.
What is your solution? Using boost is acceptable.

There is no built-in split() function in C++ for splitting strings, but there are numerous ways to accomplish the same task, such as using the getline() function, strtok() function, find() and erase() functions, and so on. This article has explained how to use these functions to split strings in C++.
You can use the std::string::find() function to find the position of your string delimiter, then use std::string::substr() to get a token. The find(const string& str, size_t pos = 0) function returns the position of the first occurrence of str in the string, or npos if the string is not found.
Something like this:
std::istringstream iss("42 4711 ");
std::vector<int> results( std::istream_iterator<int>(iss)
, std::istream_iterator<int>() );
?
