<h1 align="center">Tokenizer Class</h1>
<pre>
template <
class TokenizerFunc = char_delimiters_separator<char>,
class Iterator = std::string::const_iterator,
class Type = std::string
>
class tokenizer
</pre>
<p>The tokenizer class provides a container view of a series of tokens
contained in a sequence. You set the sequence to parse and the
TokenizerFunction to use to parse the sequence either upon construction or
using the assign member function. Note: No parsing is actually done upon
construction. Parsing is done on demand as the tokens are accessed via the
iterator provided by begin.</p>
<h2>Example</h2>
<pre>
// simple_example_1.cpp
#include<iostream>
#include<boost/tokenizer.hpp>
#include<string>
int main(){
using namespace std;
using namespace boost;
string s = "This is, a test";
tokenizer<> tok(s);
for(tokenizer<>::iterator beg=tok.begin(); beg!=tok.end();++beg){
cout << *beg << "\n";
}
}
</pre>
<p> </p>
<h3>Template Parameters</h3>

<tr>
<td><tt>TokenizerFunc</tt></td>
<td>The TokenizerFunction used to parse the sequence.</td>
</tr>
<tr>
<td><tt>Iterator</tt></td>
<td>The type of the iterator the specifies the sequence.</td>

will be at most ForwardIterator. It will be InputIterator if the
Iterator template parameter is an InputIterator. For any other
category, it will be ForwardIterator.</td>

parse the sequence.</td>
