template &lt;
        class TokenizerFunc = char_delimiters_separator&lt;char&gt;,

  <p>The token iterator serves to provide an iterator view of the tokens in a
  parsed sequence.</p>

  <h2>Example</h2>
  <pre>
/// simple_example_5.cpp
#include&lt;iostream&gt;
#include&lt;boost/token_iterator.hpp&gt;
#include&lt;string&gt;

int main(){
   using namespace std;
   using namespace boost;
   string s = "12252001";
   int offsets[] = {2,2,4};
   offset_separator f(offsets, offsets+3);
   typedef token_iterator_generator&lt;offset_separator&gt;::type Iter;
   Iter beg = make_token_iterator&lt;string&gt;(s.begin(),s.end(),f);
   Iter end = make_token_iterator&lt;string&gt;(s.end(),s.end(),f); 
   // The above statement could also have been what is below
   // Iter end;
   for(;beg!=end;++beg){
     cout &lt;&lt; *beg &lt;&lt; "\n";
